Also at that time, my father's business had launched many technological changes that led to the automation of its production line. These improvements had saved his company from bankruptcy. Visiting him and seeing how the new system had increased his profits heightened my interest in essay on chronic disease IT. I now live in fruits of sorrow essay Canada, where computers continue to play a large role in American my daily affairs. I use electronic mail and Internet chats to fruits of sorrow essay communicate with both parents, and have chosen management information systems as my course of study. Information technology fascinates me not only because it makes companies more competitive, but also because it can bridge great distances to essay discussed the tendency bring people together. I have much respect for and interest in the IT industry. Personal satisfaction also plays a key role in my career decision. While monetary rewards are of practical importance, true job satisfaction springs from the opportunity to grow and learn within an industry. I enjoy acquiring new skills and information, which help me to adapt to the fast-changing world, as well as pique my interest in of sorrow innovation.
In addition, a career with open prospects would give me constant incentive to help improve myself and to gain more knowledge. I currently volunteer for an on-campus organization, Job Web, in which I am responsible for fruits essay, posting employment opportunities on the World Wide Web, answering questions and essay on the preparing informative handouts. This position has broadened my computing abilities and has improved my interpersonal skills, which are crucial to any business endeavor. I enjoy the sense of productivity and usefulness I gain from the work, and feel it is a valuable experience for future employment. Given the confluence of my personal and professional interests, my goal is to obtain a master's degree and then to work in an IT-related industry, either with a consulting firm or as a systems analyst with a financial institution. In addition to this, I plan to fruits of sorrow use my private time to attend computer programming courses in order to maintain a competitive knowledge of technology. When I have gathered enough experience and skills, I plan to launch a consulting company of literary school, my own. Attending a Master's of fruits, Science program will smooth the obstructive pulmonary disease, path to fruits these goals.
Such a program will deepen my expertise and malthus's essay broaden my perspectives. Moreover, the MIS option will help me to hone my skills in IT areas that I have not yet encountered. As I have attended the University of of sorrow essay, Toronto for four years, I am familiar with and have confidence in the faculty professors whom I believe can help me become an IT professional. Essay 2: Describe two events in of tango your life to date that demonstrate your ability to do well in business. My classmates called me the alien, and they avoided me like the plague. As a young boy, I suffered from fruits, severe dermatitis, which filled my limbs with ulcers and scars. The true pain of my condition, however, was social; I was alienated from my classmates and lived a life of loneliness and isolation.
Doctors predicted that I would never fully recover, but my parents refused to accept this. They encouraged me to hope for the future, teaching me that any obstacle could be overcome. I therefore took an active role in my health, trying many medications and herbs. Approaching my loneliness with bravery, I came to view it as a challenge to be overcome. History Of Tango? The summer after I graduated from primary school, my disease improved dramatically. Fruits Of Sorrow? Although my body remained riddled with scars, the ulcers vanished. The self-confidence I regained was profound; I realized that my personal will had led to this improvement. Essay History Of Tango? I began to seek out friendships at school, and I took part in activities like volleyball, Girl Guide, and Art Club. Through it all, my attitude toward challenges remained the same. In every examination or competition, I told myself that I could easily excel since nothing could be more difficult than what I had already overcome.
By the of sorrow, time I moved to Canada, I had fully recovered both socially and physically. Moreover, I had learned to be confident and never to fear failure. This credo echoes through my personal life and topics in law gives me the of sorrow essay, inner resolve to succeed at essay history of tango, any endeavor, including my professional pursuits. Like my personal battle with dermatitis, I learned a great deal about leadership by overcoming adversity. While enrolled in an ESL program in Canada, I joined the of sorrow, Culture Club as a Special Event Director.
I managed a group of dissertation topics in law, six individuals in organizing various functions. I was the most advanced ESL student among the group, and I therefore assumed myself to be the most capable. Fruits Of Sorrow? I quickly learned my mistake. While preparing our first function, I was strict with my team members and often rejected their ideas in favor of my own. I performed most of their tasks myself, allowing them to assist me only in minor details. As a result, the function was not very successful.
Few people attended, and we had problems with decorations and presentation. The setback disheartened me, and I spoke of it to the club's supervisor. She responded that she trusted my ability to succeed in the future. This comment filled me with surprise, for I realized that I had never trusted my own team members. Although they were weak in English, they had many valuable talents. Help Me Write A Personal? I immediately changed my policy, allowing team members to choose the tasks they desired and to essay complete them on their own. Meetings evolved into group brainstorming sessions, which yielded many good ideas. Most importantly, the topics in law, atmosphere among us improved dramatically. We were happier and more eager to devote time to the program. I learned what true leadership is, and the experience undoubtedly improved my ability to handle challenging business situations.

Essay Rubric Middle School? Click Here for the Edited Version. This is a strong pair of essays that puts a very human face on your application. You come across as an engaging and fruits of sorrow essay likeable IT professional, and the details you provide about malthus's essay principle of humans your personal life are both interesting and informative.
However, there were ways in fruits essay which these essays could be improved. The major problem I noticed with these essays was the topics in law, length of essay, your paragraphs. It is necessary to literary essay rubric middle school break your discussions into easily digestible segments so that the fruits essay, reader is not overwhelmed by the breadth of obstructive pulmonary disease, your observations. I have substantially reworked the structure of these essays to fruits make them more accessible to South American Map the reader. Throughout each essay, I took liberties to correct stylistic and grammatical problems. My changes largely took the form of making sentence transitions smoother and more compelling, varying sentence structure to keep the reader interested, and fruits of sorrow essay pruning unnecessary words to increase sentence comprehension and coherence. I consciously tried to leave your own voice and ideas intact. Here are my specific notes on each original paragraph of the text: The first few sentences of your original draft seemed too self-pitying. South American Map? It is essential to begin your essay with something that captures the fruits of sorrow, reader's interest. I have provided a new introduction that illustrates the unique role that the Internet played in your family dynamic.
In addition, it is useful to separate the introduction proper from the rest of the first paragraph. I have provided a strong transition that illustrates the pulmonary, relevance of your volunteer IT experience. Finally, the new second paragraph that I have adapted from your original text incorporates extensive sentence-level adjustments to improve your diction. When I visited him, the of sorrow essay, new automated production line and the whole computerized firm amused me. It is best to help me write a personal omit this detail since it suggests that you failed to appreciate the difficulty of your father's work. See the alternative treatment of this idea I have proposed in the revised essay.
I provided a stronger transition to this sentence, which encapsulates your main motivation for pursuing a career in fruits of sorrow essay IT. Malthus's Principle Of Population Discussed Of Humans? Your original paragraph was a bit too general, so I anchored your assertions in concrete fact to make them more compelling. Although monetary reward is practically important in reality. This is redundant. Of Sorrow? I suggest the following: While monetary rewards are of practical importance. I like learning new skills and acquiring up-dated information, because they can help me adapt the fast-changing world, enrich my experiences, explore my interest, and give me higher self-esteem as I am a valuable person. This is too effusive. I have provided a shorter version of this idea below. I have improved the diction of this paragraph to make it more compelling.
I will attend a computer-programming course in malthus's the tendency of humans order to continuously update myself and become more competitive. This construction is slightly awkward. You can rephrase this idea as follows: I plan to use my private time to attend computer programming courses in order to maintain a competitive knowledge of of sorrow, technology. I have adjusted the tone of dissertation topics, this paragraph to use a more confident voice. For instance, I replaced the phrase, the program can deepen expertise, with, such a program will deepen my expertise.
This adjustment is fruits essay, subtle, but it makes a big difference. Your original introduction failed to introduce your subject to the reader in an adequate fashion or to engage his attention. Help? Rather than summarizing your arguments in an essay this short, it is better to provide a hook that draws your reader into the piece. See my suggestion in the text. This paragraph was too wordy, and many of your arguments were redundant. I have streamlined your discussion to of sorrow essay make it more direct, and I have separated this paragraph into South Map, two parts to make it more readable. In addition, it was necessary to reduce the graphic description of your physical ailment. Fruits Of Sorrow? It is better to focus on malthus's on the of population discussed how you overcame adversity rather than to dwell on how you suffered as a child. . full of ulcers, sores, bandages and scars. I always felt itchy and fruits painful, and I dared not play with others. Moreover, my hairs had never been longer that two inches.
These are distracting details that fail to illustrate how you overcame adversity. I suggest reducing these descriptions to middle school a minimum. During every examination and competition, I told myself that I was able to do the of sorrow essay, best because nothing was tougher than the time when I was in the primary school. This is a very powerful argument that does a great job of pulmonary disease, illustrating your resolve. I have highlighted and expanded upon this idea in fruits of sorrow essay the revised essay. This paragraph is also best divided into two separate parts. To ensure that your essay reads smoothly, I have provided new transition sentences to each paragraph.
However, I quickly found that I was wrong after we completed our first function. This is a good place to essay rubric school vary sentence length for dramatic effect. I propose the following: I quickly learned my mistake. I followed up my members' tasks very strictly and did not accept their idea very often. While it is important to be honest, you should cast this detail in the most favorable light possible.
I propose the following: I was strict with my team members and fruits essay often rejected their ideas in help me write statement favor of my own. With all the changes I have proposed, you will have to fruits of sorrow use your judgment and accept only those which you think are best. Overall, these essays now do a very good job of putting a human face on your application. I wish you the best of luck in the application process.

DEES Graduate Student Dissertation Topic List. Date Orals Passed: 5/15. Advisory Committee: Gaherty, Shillington, Ekstrom. Investigation of the Role of Segmentation and Magmatism in Continental Rifting Exploiting Diverse Seismic Datasets from the East African Rift System. For many years it has been accepted that continental breakup occurs by fruits of sorrow essay extension and ultimately rupture of the lithosphere. However, the emergence and early evolution of two fundamental characteristics of divergent plate boundaries, segmentation and magmatism, are not well understood because most studies focus on mature or successfully rifted margins. Additionally, there are few existing datasets that can be integrated to provide 3D constraints on rift architecture throughout the lithosphere, which are required to address these questions. My research focuses on investigations of the crust and uppermost mantle structure beneath two unique end-member study locations within the East African Rift System (EARS). The first component of my dissertation concerns the mature Main Ethiopian Rift and Afar Depression.
I used earthquake and continuous data from 100+ temporary seismic stations located in the region to investigate the shear velocity and radially anisotropic structure of the uppermost mantle. This investigation produced estimates of mantle temperature and melt content within the rift and also highlighted the potential location of melt segregation along a steeply dipping lithosphere-asthenosphere boundary. The second component of my dissertation focuses on the relatively immature Malawi Rift located at the southernmost tip of the EARS. Of Tango? For this study I am using the recently acquired SEGMeNT active and passive source seismic dataset that comprises a 3D array of of sorrow essay, on-land and a personal, lake-bottom broadband and short period seismometers. With this data I plan to investigate the shear velocity structure of the uppermost mantle beneath the region using teleseismic and ambient noise seismic processing. The 3D active source dataset acquired by short period lake-bottom seismometers within Lake Malawi will provide high-resolution images of shallow crustal velocity structure. Together these diverse datasets will yield novel constraints on the state of the Malawi Rift and the role of segmentation and magmatism in an immature continental rift setting.

Dissertation Topics? The emphasis of my work is on sedimentary and stratigraphic observations that I use to interpret lake level fluctuations--a proxy for fruits changes in the basin's precipitation minus evaporation balance. I hope that this, along with a chronology based on uranium series and essay school, radiocarbon data, can yield an accurate and precise record, which can be used by climate modelers to understand the hydrosphere's dynamics.

My graduate research at the interface of of sorrow essay, marine biology and chemical oceanography addresses the impacts of regional climate change on microorganisms in coastal marine ecosystems. Much of topics in law, my research focuses on the effects of multiple stressors on the growth and physiology of planktonic microorganisms, which form the base of the marine food web and serve as some of the first bioindicators of change in marine ecosystems. Of Sorrow Essay? Although the essay history of tango, effects of ocean acidification are known for some marine plankton, the interactive effects of ocean acidification and other chemical stressors (e.g., hypoxia, toxic trace metals delivered from suspended sediments, antibiotics) are not well understood.
Using integrated laboratory experiments and field studies, I examine the interactive impacts of ocean acidification with other chemical stressors on harmful algal bloom (HAB) phytoplankton species including Cochlodinium polykrikoides and Amphidinium carterae , as well as shelled molluscs including Limacina helicina . In addition, some of my research focuses on the supply of dust – a major source of iron for phytoplankton – in fruits essay, surface waters of the Map, Indian Ocean. Using trace metal clean laboratory techniques, I measure thorium isotopes in seawater and surface sediment samples to determine the total atmospheric dust flux to the Indian Ocean. These interdisciplinary studies address the coupled biological and chemical changes in of sorrow essay, marine ecosystems as a result of increased anthropogenic climate change.

The study is particularly focused on seismicity before and after a well-documented submarine eruption at this site, which culminated in a seismic crisis on January 22 nd , 2006. This study enables us to observe the fundamental change in the state of stress along a mid ocean ridge through a plate spreading event.
For my second and third chapter, I am looking at fruits of sorrow, the morphology, origin and evolution of Pleistocene submarine canyons at malthus's essay on the of population discussed, the New Jersey margin. Essay? For this purpose, I am using the 2D seismic reflection profiles collected on R/V Oceanus cruise 270 in 1995. Mapping the submarine canyons allows me to study their progression in morphology through space and time. For a greater understanding of the effects of sea level change on essay on the of population the tendency of humans, a stratigraphic column, a 3D seismic volume was just acquired on the New Jersey continental shelf, aboard R/V Langseth in the summer of 2015. Fruits Essay? I participated in the cruise and malthus's essay on the of population of humans, awaiting the delivery of the processed dataset early next year. I am planning to look at the evolution of Miocene clinoform fronts at this margin. In my last chapter, I am going to evaluate the ocean crustal sites at Reykjanes ridge, offshore Iceland for carbon dioxide sequestration in fruits of sorrow, layers of deep-sea basalt. This work aims to essay on chronic obstructive, look for fruits of sorrow an offshore extension of the onshore CarbFix project launched in 2007.

Advisory Committee : Winckler, Goldstein, Kaplan. The provenance of mineral dust in West Antarctica: Insights into past atmospheric circulation and continental aridity. Mineral dust lofted up into the atmosphere has both a direct and an indirect effect on topics in law, the climate system. My research focuses on understanding the fruits essay, ways that dust influences the climate system today, and South Map, how that influence has changed in the past. In particular, we can use dust as a tracer of past atmospheric circulation patterns: by comparing the radiogenic isotopic “fingerprint” of places where the dust might have come from with the signal we see in some climate archive, we know that storm systems transported that dust from that known source to our location of interest. Then, we can see how the source areas may have changed over time. My samples come from several ice cores in West Antarctica (WAIS), and of sorrow, we use Sr, Nd, and Pb isotopes to identify the changing dust sources to WAIS on glacial-interglacial and on chronic pulmonary, millennial timescales, as well as during even shorter-term events such as volcanic eruptions.

Paleoceanographic-Proxy Development in Scleractinia (Stony Corals) Throughout the Pacific Ocean: Exploring the Variable Utility of Stable Isotopes and Trace Metals in Oceanographic Reconstructions. The geochemical signature in of sorrow, the aragonite skeleton of a coral can be used to in law, decipher past climate. In particular, stable isotopes and trace metals are used to elucidate changes in sea surface temperature (SST), sea surface salinity (SSS), or coastal river discharge. My dissertation research is a compilation of projects aimed at fine-tuning and exploring the bounds of coral paleoceanographic proxies. Using stable oxygen isotopes from corals off the Pacific coast of Panama I am reconstructing decadal precipitation patterns to better understand low frequency variability in the Pacific Basin. In conjunction with the precipitation record, I am studying the viability of coral Ba/Ca as a terrestrial run off proxy in the same region to better understand the impacts of fruits, oscillating precipitation in essay obstructive disease, the Eastern Tropical Pacific.
In addition I am developing Sr/Ca- and oxygen isotope-SST calibrations for of sorrow corals in Map, the Great Barrier Reef. This calibration will be applied to fossil corals dating back to the Last Glacial Maximum to help us understand SST change in the Great Barrier reef during the most recent glacial to interglacial transition. Ultimately, my research explores the various types of coral paleo-proxies and how their applicability can vary in different oceanographic settings. My findings will underscore the need to fruits essay, consider the location of interest when choosing the most appropriate proxy to interrogate past climate change. Date Orals Passed: 4/13.

IR imagery not only provides a measure of skin temperature, but can also be used to infer surface currents. Structures and help me write, variations in the skin temperature arise from disruption of the thermal boundary layer (TBL) as a result of wind forcing at the air-water interface and/or due to turbulent eddies generated within the water column. The TBL makes up top few micro meters of the water column and of sorrow, the key intermediate between the ocean and atmosphere, which plays a crucial role in heat and gas exchanges. My studies aim to infer subsurface and bulk water column characteristics such as turbulent kinetic energy dissipation, and water depth from American non-intrusive surface measurements of the thermal boundary layer.

Understanding the fruits of sorrow, global freshwater cycle is topics in law, of tremendous importance in order to fruits of sorrow, understand and adapt to future climate change. The ocean is inherently linked to the global freshwater cycle. Positive net evaporation (evaporation - precipitation) constantly remove freshwater from the surface in the subtropics creating a local maximum in sea surface salinity while the tropics are freshened by excess rainfall. To balance the loss in freshwater in the subtropics, ocean processes need to essay on chronic obstructive pulmonary disease, mix in surrounding waters laterally and vertically. The mainly wind driven shallow overturning circulation, defined by poleward Ekman drift at the surface, subduction in the subtropics and upwelling in the equatorial regions carries the salty surface signature beneath the surface creating a subsurface salinity maximum. Recent advances in remote salinity observations and essay, a comprehensive field campaign (NASA-SPURS) enable us to study the influence of mesoscale eddies for the surface salinity maximum as well as the subsurface salinity maximum in the North Atlantic. My dissertation aims to quantify the malthus's on the of population discussed the tendency, importance of mesoscale turbulence to the surface salinity maximum in the North Atlantic and identify links to large scale climate variables using a mix of fruits essay, observational data and simplified model experiments. Further more I aim to identify key processes that influence the subsurface salinity maximum once isolated from the surface forcing, hence influence the heat/salt transports through the shallow overturning circulation. Specifically the role of essay obstructive, double diffusive processes for the salinity core layer and associated transports will be evaluated. Finally these results will be compared to the shallow overturning circulation and salinity maxima in other ocean basins and evaluated whether they can explain regional differences and fruits, account for inter annual variability.

Advisory Committee: Cane, Ting, D. On Chronic Obstructive Pulmonary? Chen. Integrated evolution of the atmosphere-ocean coupled modes. El Nino and the Southern Oscillation (ENSO), Pacific Decadal Oscillation (PDO), and Atlantic Multidecadal Oscillation (AMO) are a few significant modes of fruits of sorrow, climate variation from interannual to multidecadal time scales identified from sea surface temperature (SST). It is South, well known that ENSO dynamics involves tropical atmosphere-ocean (AO) coupling. Of Sorrow? As to American Map, the PDO and AMO, they are also viewed as the outcome of coupling, yet there is no well-accepted theory about the mechanism involved. Thus, one aim of this thesis is to explain this low frequency AO coupling and how it leads to fruits, the observed climate variation.
Based on the heat budget equation, the temperature variation or tendency is determined by the horizontal heat advection (by ocean gyre circulation), vertical heat advection (by upwelling or downwelling), and dissipation (interior ocean mixing) as well as the AO interface heat flux. In order to look into pulmonary, the ocean’s role, estimation of the relative significance of fruits essay, each term will be done using the output from coupled climate models. The time variation of each term will also be investigated using time series analysis tools and literary essay middle school, other statistical methods (linear inverse model) to assist the fruits, explaining of the mechanism. The basic assumption in this work is malthus's principle the tendency, that the coupling is not a local phenomena but on a basin wide or global scale, which is fulfilled through the oceanic and atmospheric circulation. By studying this topic, we attempt to understand the fundamental question of how heat is transported through AO coupling within the fruits essay, climate system. Further question to be addressed will be how the modes of coupling will change under the topics in law, global warming condition. Date Orals Passed: 4/12.

Urodela (salamanders) are a major group of modern amphibians (Lissamphibia), with a long evolutionary history that can be traced back to the Mezozoic dinosaur time. Of Sorrow Essay? Phylogenetic studies of salamander evolution have revealed sharp conflict between the hypotheses based on morphological data and/or molecular data. The proposed research intends to conduct combined analyses incorporating phylogenetically significant early fossil taxa, all available morphological and molecular data; a method herein termed “Fossils-Morphology-Molecular Approach” (FMM approach). Such an disease approach has the advantage in resolving or relaxing the morphology/molecular conflicts, and obviously the essay, advantage in obtaining phylogenetic hypotheses with the ultimate power of malthus's essay principle of humans, scientific explanation. Fossil discoveries from the Middle Jurassic to of sorrow essay, Early Cretaceous beds in northern China have provided the malthus's essay on the, key material for understanding the origins and early evolution of fruits, modern salamander clades.

Subglacial hydrology is one of the main controlling factors in the spatial and temporal evolution of ice flow: how the water drains underneath an ice sheet has important implications for the basal sliding condition. However, subglacial water drainage is dynamic in space and topics in law, time and varies in a complicated manner coupled to surface hydrology. Despite recent conceptual advances, relatively little is known about how the essay, surface hydrology interacts with the South American, subglacial drainage system and how it affects effective pressure and ice flow. Currently, I am working on building a 2D numerical model of subglacial drainage to investigate the coupling between drainage of surface melt water and glacier motion.

Constraining Chemical Environment and Processes in the Protoplanetary Disk: Perspective from Populations of Calcium- and Aluminum-rich Inclusions and Metal-rich Chondrules in Carbonaceous Ornans-type and Renazzo-type Chondrites Respectively? On Earth, petrologic and geochemical analyses provide insight into the Earth’s bulk composition as well as the interior and exterior processes that have been operating throughout Earth’s history as a planet. South Map? To understand the origin of the Earth and other terrestrial bodies, the chemical construct and dynamic processes operating in fruits essay, the solar nebula, a cloud of cooling gas and dust existing after sun formation, need to be constrained. Me Write A Personal? The history of the early solar system is preserved in the various components in chondritic meteorites. Chondrites have never experienced the significant planetary process of differentiation, which separates metals from silicates, and remixes chemical components. Thus, they can be considered aggregates of objects formed in the dynamic, cooling solar nebula. Fruits Essay? Ca- and Al-rich inclusions (CAI) are some of the highest temperature solids formed and dissertation topics in law, preserved in chondrites.
Chondrules are varied in mineralogy but those containing discrete metal layers record unique conditions relating to the heating and deformation history of the chondrules with which they are associated. The chemistries , textures, and mineral crystal orientations of CAIs and chondrules directly reflect the fruits essay, conditions and processes in their formation in the nebula. While many previous studies have chosen to focus on a few objects in detail, my study aims to examine many inclusions to better understand chemical, mineralogical, and textural variations and correlations. ? A majority of my research focuses on high resolution, x-ray element map analysis of individual CAIs and other objects in carbonaceous Ornans-like (CO) chondrites using custom-made image analysis software. But, to obtain a more complete understanding of complementarity, or the concept that bulk CO chondrite has a solar composition while individual components do not, I am analyzing the rare-earth element (REE) ratios in individual components. Determining the relationship between object mineralogy, texture, and REE ratio will yield insight into the occurrences of various components and their relative proportions that must combine to maintain solar composition within the bulk chondrite. This broad survey of CAIs and essay, other objects in CO chondrites will help constrain astrophysical models, refine the order in which minerals condense from the solar nebula, and further improve the formation criterion necessary to produce the fruits of sorrow, observed variation. ? Chondrule formation hypotheses are many but poorly constrained. The chondrules in carbonaceous Renazzo-type (CR) chondrites have associated metal in both the dissertation topics in law, chondrule core and near the rim. Electron backscattered diffraction (EBSD) permits determination of metal crystal orientation. Determining the relationships between the crystal orientation and chemistry of metal nodules within and among the chondrules could yield insight into chondrule formation and deformation.

Advisory Committee: Class, Goldstein, Hemming. Melt depletion and geochemical evolution of the subcontinental lithospheric mantle in the West Antarctic Rift System. The subcontinental lithospheric mantle (SCLM) undergoes compositional changes during tectonic events such as continental rifting, subduction, and orogeny, with each event leaving behind a geochemical imprint. Essay? Geochemical mapping of the lithosphere allows us to dissertation topics in law, gain a better understanding of how the fruits, continents are structured, and enables us to piece together the tectonic evolution of the continents. Here we look at the Western Ross Sea area of the essay history of tango, West Antarctic Rift System (WARS) as a case study. My thesis focuses on using these geochemical imprints to unravel the geochemical and tectonic evolution of the SCLM in the WARS: Os isotope ratios can be used to date the fruits of sorrow essay, melt depletion events in the asthenosphere that are considered to be equivalent to the stabilization age of the lithospheric mantle.
In this study, mantle xenoliths entrained in Cenozoic basanites were collected in a transection from the rift shoulder and into the rift basin in the western margin of the WARS. Literary Essay Middle School? Analyses of these samples provide a recent snapshot of the lithospheric mantle after major episodes of rifting. If we can trace the age of the lithospheric mantle across this margin, we can begin to essay, understand its behavior in response to essay obstructive disease, rifting and subsequent structure. We repeatedly observe. 1.7 Ga depletion events across the rifted margin, indicating the widespread Paleoproterozoic stabilization of the lithosphere and dynamic thinning of lithosphere across the fruits, western margin of the WARS. Trace elements provide another means to access the depletion history of the SCLM, however the malthus's essay on the of population discussed of humans, mobility and fractionation of these elements can obscure ancient depletion signatures. Nevertheless, we can exploit the fruits of sorrow essay, behavior of these trace elements. Help A Personal? For example, melt depletion is characterized by fruits of sorrow essay light rare earth element (LREE) depletions, however we observe LREE enrichments in statement, our 1.7 Ga xenoliths. Metasomatism, the chemical alteration of a rock via melt and/or fluid, can overprint the trace element composition of a rock, leaving behind diagnostic signatures of the metasomatizing agent (e.g. LREE re-enrichment by a carbonatitic melt).
Sr-Nd-Hf-Pb isotopes can be used to constrain the fruits, role of the SCLM in the formation of WARS volcanism. It has been proposed that Cenozoic basaltic volcanism in the Northern Victoria Land (NVL) region of East Antarctica originated from a SCLM source that had been metasomatized during an extensional event in the WARS during the Late Cretaceous. Additional studies demonstrate that Nd and Sr isotope ratios plot near the HIMU field, yet Pb and Hf isotope ratios plot between HIMU and DMM. This can be accounted for by varying proportions of lithospheric mantle source that has experienced Paleozoic to essay on the history of tango, Mesozoic modification due to subduction related fluids and flux melting which can incorporate fluid mobile elements such as Pb from the mantle wedge. By measuring these same isotope systems on mantle xenoliths, we can begin to address whether SCLM is a source for the widespread Cenozoic volcanism in the WARS. Date Orals Passed : 4/14.

Recent observational and modeling studies have shown that wintertime variability of the fruits essay, stratospheric circulation is dynamically coupled to on the of tango, anomalous weather regimes in the troposphere. The fundamental source of the coupling is planetary-scale waves which are primarily generated in the troposphere and couple vertically with the of sorrow essay, stratosphere when the zonal-mean winds are westerly. My research focuses on understanding the help me write a personal statement, dynamics of extreme stratospheric planetary-scale wave events and their coupling to the stratospheric and tropospheric circulations. My results show that the lifecycle of upward wave propagation/downward wave reflection events are associated with vertically deep planetary wave structures that exhibit largely equal but opposite-signed time integrated impacts: a net deceleration/acceleration of the stratospheric polar vortex and an equatorward/poleward shift of the North Atlantic tropospheric jet. Downward wave reflection events are found to play a key role in the formation of strong vortex events showing that they both represent true dynamical events with strong wave-mean flow interaction. Together with the connection between upward wave propagation and weak vortex events, the fruits of sorrow, results illustrate a clear dualism in essay on chronic obstructive disease, stratospheric wave-mean flow interaction. Planetary wave events are focused in high-latitudes and produce large amplitude tropospheric impacts and hence represent a key dynamical pathway through which Arctic variability can impact the midlatitude circulation. My current research aims to address the question of fruits essay, why stratospheric planetary wave events become extreme in high-latitudes. Several mechanisms have been proposed in the literature such as stationary-transient wave interactions, instability and resonance.

Models of seismic anisotropy in oceanic regions provide information about the geometry of strain and of sorrow essay, flow in the mantle, the specific nature of the lithosphere-asthenosphere boundary, and the possible presence of partial melt in the asthenosphere.
In order to investigate these and other questions, my research is focused on developing a three-dimensional model of the essay on the history of tango, anisotropy velocity structure of the Pacific upper mantle. Fruits? Using measurements of fundamental mode surface waves, we invert for variations in seismic velocity laterally and with depth in the upper mantle of the Pacific basin. In addition to variations in on the of humans, isotropic velocities, we include in the inversion the elastic parameters describing both radial and azimuthal anisotropy.

My first major research project focused on the Woodlark Rift in southeastern Papua New Guinea.
This is one of the youngest and fruits essay, most rapidly extending continental rifts in the world, and is an intriguing locality for investigating how continents break apart. The D'Entrecasteaux Islands, at the heart of this rift, comprise metamorphic core complexes that contain the world's youngest ultra-high pressure coesite eclogite, exhumed from American 100 km depth in just 5 Ma. I have applied a variety of seismological techniques to investigate this region, using data from a temporary array of broadband seismometers installed by members of the LDEO seismology dept. Of Sorrow Essay? that ran from 2010-2011.? My analysis of shear-wave splitting, using core-traversing teleseisms, shows strong anisotropy beneath this rift, attributed to crystallographic fabric in the shallow mantle caused by the rate and extent of obstructive, continental rifting. I have related anisotropy and shear strain in the shallow convecting mantle to predict shear-wave splitting times that are very close to the splitting times I observe, bolstering our hypothesis that the anisotropy arises from mantle fabric related to rifting. These findings shed light on how mantle flow transitions as a rift matures from fruits essay a small-scale extensional regime to a large-scale divergent boundary.? We conducted a body-wave tomography study in the same region, using teleseismic P- and S- wave arrivals, and taking a finite-frequency approach to relate differential travel times to 3D velocity heterogeneities. The isotropic velocity model reveals a localised rift structure evident to ?180 km depth, as well as an apparent slab remnant that contains the essay principle of humans, first intermediate depth seismicity observed in this region, discovered last year by members of our research group.
Building upon this work, I developed a new method to jointly invert for anisotropy and velocity variations in this rift by simplifying the geometry of the anisotropic fabric based on the rift geometry and the SK(K)S splitting results. Fruits? This work revealed that the rift axis contains anisotropic material with spreading-parallel fast axis, that is breaking upwards through lithosphere that has spreading-perpendicular fast axis (aligned with the trend of recent orogenies).

Ice core records of atmospheric carbon dioxide (CO2) support a tight linkage between CO2 concentrations and South Map, climate over Quaternary glacial-interglacial cycles. On millennial timescales, atmospheric CO2 concentrations are driven by the deep ocean, which holds the largest reservoir of exchangeable carbon.
The nature and phasing of fruits essay, relationships between deep ocean circulation, the oceanic carbon cycle, atmospheric CO2 and climate remain enigmatic, and are all the more important considering recent anthropogenic perturbation of the global carbon cycle.

My thesis will include at least three chapters: The first chapter is focused toward gaining an understanding of surface processes, fluid flow, faulting/compaction, and sediment physical properties outboard of the deformation front at the Cascadia Subduction Zone.
To obtain this goal, I am using 2D multi-channel seismic (MCS) and multi-beam sonar (MB) data collected offshore Oregon and Washington during the fruits essay, Cascadia Ridge to Trench survey in 2012. I first performed detailed p-wave velocity analysis to achieve. sub-surface perspective on seafloor surface related fluid flow features (e.g. pockmarks).

As an additional project, I mapped large-scale scour marks on the distal Astoria Fan and. then inverted for the source process azimuth. Malthus's Principle Discussed? The azimuths all point toward the Astoria canyon, which is the extension of the Columbia River, and therefore, may be indicators of seafloor erosion due to late Pleistocene outburst flooding events. The second chapter involves mapping amplitude variations along with specific surface seismic attributes across sub-surface paleo-channels and related rift-block bound basin unconformities within the Galicia 3D MCS dataset collected offshore Spain in fruits essay, the summer of 2013. The 3D volume is. 20km x 67km and has been processed to help statement, pre-stack time migration.

Abrupt climate change has been shown to fruits of sorrow, occur synchronously with changes in the vigor of the me write a personal statement, oceans’ circulation. As oceans redistribute massive quantities of heat across the Earth’s surface, changes in their circulation are often invoked as playing an important or perhaps driving role in these past climate changes. Many high-resolution climate records, generated over the past two decades, have provided glimpses into fruits, these past climate events; however, the equivalent, detailed record for changes in the oceans overturning circulation remains elusive. My thesis research focuses on essay middle school, refining, Pa/Th, a proxy that will help us generate a more detailed understanding of the relationship between climate and changes in ocean overturning.

The Cascadia subduction zone, where the Juan de Fuca plate subducts beneath the North American plate, has historically produced large, approximately M9, megathrust earthquakes. Improved knowledge of the structure of the dissertation topics in law, subducting crust and mantle can help us better understand the processes that control subduction, including those related to megathrust earthquakes. We use three seismic datasets to fruits essay, image different properties of the region at different scales.

An approximately 35 km long region of high amplitude reflections has been observed perpendicular to me write, strike spanning the coastline. These may be explained by differences in physical properties, ray geometry or a combination thereof.

Current seismic behavior and variation of seismic reflectivity signature for megathrust in the Alaska/Aleutian Subduction zone.
Great earthquakes occur in the seismogenic portion of fruits, subduction zone megathrusts. Although most subduction zones show small to moderate interplate thrust earthquakes during the intervals between great earthquakes, a few show only South American, seismicity within the fruits of sorrow essay, downgoing slab, not on me write, the plate interface, even at megathrust depths. The different patterns of seismic behavior could reflect different levels of material heterogeneity on megathrust. Downdip of the fruits of sorrow essay, seismogenic zone, the megathrust changes from stick-slip behavior to stable sliding. Competing models suggest that the American, transition is controlled by temperature or the intersection of the megathrust with the serpentinized forearc mantle wedge.
In some subduction zones, changes in fruits, behavior appear to be accompanied by changes in seismic reflection signature. The Alaska/Aleutian subduction zone is one of the best places to study the dissertation, relation between megathrust property and seismic hazard. During the 20th century, virtually the entire Alaska-Aleutian subduction interface has ruptured in large to great earthquakes. The 1964 Mw 9.2 Earthquake ruptured some onshore area, allowing us to deploy a broadband seismic network (MOOS array) to study the details of the current seismic behavior. Further west, the rupture zone of 1938 Mw 8.2 Earthquake lies completely offshore and is fully accessible to marine profiling. The megathrust of the Alaska/Aleution subdction zone also exhibits large variations from locking to freely sliding along strike from recent GPS study. My thesis focuses on the seismic behavior and reflectivity of the megathrust in the Alaska/Aleutian subduction zone and consists of: 1. A detailed study of seismicity recorded by the MOOS array. We generated a seismic catalog with 8,308 earthquakes down to magnitude 1.0 with high precision and calculated 117 focal mechanisms from the of sorrow, data recorded by MOOS array. Most microearthquakes are showing normal faulting mechanisms, and the direction of the T axes generally follows the dipping direction of the dissertation, slab, indicating that they lie inside the subducting slab under down-dip extension or result from of sorrow plate bending.

Anthropogenic aerosols remain one of the largest sources of uncertainty in our understanding of and ability to of tango, project present and future climate. I examine the effects of anthropogenic aerosols on regional climate in the United States, with a focus on extreme events and the southeast U.S. “warming hole”. I examine changes in frequency, magnitude, and duration of extreme temperature, precipitation and stagnation events. Extreme atmospheric stagnation events, characterized by persistent weak winds and lack of precipitation, are of particular concern for air quality and human health. The lack of ventilation and fruits of sorrow essay, scavenging by precipitation allows pollutants to South American, build up to dangerous levels in the boundary layer. This creates a potential feedback between air pollutants (atmospheric aerosols) and the meteorological conditions that contribute to extreme pollution events. Using the fruits, GFDL-CM3 chemistry-climate model, I find that aerosols have reduced the frequency and topics in law, magnitude of high temperature extremes over the U.S. between 1860 and 2005, while decreasing the frequency and magnitude of extreme precipitation, particularly in the eastern U.S.
As a result, aerosols have largely cancelled out the of sorrow, effects of greenhouse gases over on the discussed the historical period. However, emissions of anthropogenic aerosols are projected to decrease in the future, unmasking the of sorrow, impacts of greenhouse gases during the Map, next few decades.? The modeled spatial response pattern of extreme temperatures to both aerosols and greenhouse gases is characterized by a strong response in the western U.S., moderate responses in the central and northeast U.S., and a weak or absent response in the southeast U.S., collocated with the observed “warming hole”, one of the fruits of sorrow, few regions across the globe which has not warmed significantly over the twentieth century. I find that the weak temperature response in this region is tied to changes in the moisture budget, driven by changes in essay on the of population, regional circulation patterns and the westward extent of the Bermuda High. I will use results from fruits of sorrow multiple global climate models to evaluate how the frequency, intensity, duration, and spatial extent of U.S. stagnation events change in response to forcing from essay obstructive pulmonary disease anthropogenic aerosols. I will use observations of essay, U.S. air stagnation from NCDC in conjunction with GFDL-CM3 to examine specific large-scale stagnation events (such as summer 2012) and identify key atmospheric drivers (such as changes in the Bermuda High).

The west Antarctic Peninsula (WAP) is rubric middle, bordered by the Antarctic circumpolar current (ACC), which flows adjacent to of sorrow essay, the continental shelf.
Below the permanent pycnocline, the ACC advects upper circumpolar deep water (UCDW), characterized by essay on chronic pulmonary temperature and fruits of sorrow, nutrient maxima. Understanding the transport of UCDW onto the WAP shelf is important for two main reasons. Firstly, the available heat of circumpolar deep water is believed to be partly responsible for on the of tango recent increased melt of marine glaciers. Fruits Of Sorrow Essay? Secondly, as a nutrient-maximum (macro, but more importantly, micro), the essay obstructive pulmonary, transport of UCDW onto the WAP shelf influences the local ecosystem. One of the essay, primary goals of my research is to understand the processes of shelf-slope exchange along the rubric middle, WAP margins. To date, I have identified that intrusions of UCDW to the WAP shelf are episodic with a frequency of about 3-4 per month and a size on fruits of sorrow essay, the order of the first baroclinic Rossby radius. There is a mesoscale structure to the UCDW boluses which is shown to originate in the baroclinic instability of the shelf-break current upstream. Essay On The History Of Tango? The advective component of the intruding current is coherent with the along-slope wind stress in the weather-band and of sorrow essay, intrusion sites are tied to bathymetry at the shelf break (both cross-cutting canyons and seaward-veering isobaths). I am now testing the hypothesis that nonlinearity of the literary rubric school, weakly stratified flow induced by wind bursts facilitates the essay, crossing of of population the tendency, linear potential-vorticity conserving contours and allows episodic penetration at these topographically-determined sites.
The hope is to isolate essential dynamics so as to extend these findings to regions of similar shelf-break and fruits, current configuration around the Antarctic continent. Topographically-independent exchange of a yet-unquantified amount may occur as well via interleaving. A parallel goal of my research is to quantify the modification (by vertical and school, lateral mixing) of the intruding water mass. Since there are no microstructure observations on the WAP shelf, this largely involves parameterizations (Richardson number-based and internal wave shear/strain-based) and inversion methods applied to budgets of conserved properties.

Magmatism at of population discussed the tendency of humans, the southern end of the East African Rift System - origin and role during early stage rifting.
The process of fruits, continental rifting is fundamental to modern tectonic theory, yet details of the emergence and early evolution of literary rubric middle school, continental rifts are still poorly known. I use geochemical tools to reconstruct the sources and fruits of sorrow, timing of rift magmas as part of an integrated study that examines magmatism segmentation - two fundamental features of nascent divergent plate boundaries. The southern East African Rift exhibits pronounced segmentation and crustal thinning despite being nearly devoid of magmatic activity. The Rungwe Volcanic Province in Tanzania is the only volcanic region in dissertation, the southern 1000 km of the rift. Physical models require magmatism at the onset of of sorrow essay, continental extension, but Rungwe is too small volume and located in the wrong place to serve this purpose. A detailed investigation of the timing and pulmonary, chemistry of Rungwe eruptions could shed light on the role of these volcanoes in initiating and sustaining regional extension. A number of geochemical approaches are employed to fruits, better understand how existing volcanoes developed at South, Rungwe. Eruption ages, obtained using Ar-Ar isotopic ratios in the rocks, help track the initiation and frequency of eruptive activity in the context of regional tectonic extension. Of Sorrow Essay? Isotopic fingerprints of these lavas give context of topics in law, how the mantle source here relates to sources around the globe. Of Sorrow Essay?

Access to fruits of sorrow essay, safe water is a personal statement, a fundamental human need and therefore a basic human right –Kofi Annan, the UN Secretary General rightly pointed out our rights to water and sanitation. Fulfillment of such a basic need is a challenge in many parts of the fruits essay, world because of essay history, either limited water supply or contamination of the available water. My research tries to answer questions about the fate and transport of arsenic (As), a metalloid naturally present in of sorrow essay, groundwater around the world that threatens the help a personal statement, lives of tens of millions of people drinking untreated well water, particularly in South and Southeast Asia. My study assesses long-term temporal variability of of sorrow essay, shallow (30 m) groundwater arsenic concentrations across a 25-km 2 area of malthus's essay the tendency, Araihazar, Bangladesh, where a team of health and earth scientists have been conducting research since 2000. Comparisons of test results spanning more than a decade indicate significant changes. The observed trend shows that As concentrations in areas with initially high levels have declined whereas concentrations in of sorrow, areas with initially low levels have increased.

Cross-timescale Interference and American Map, Climate Predictability of Rainfall Extreme Events in fruits, South East South America. My research focuses on the physical mechanisms and potential predictability associated with climate extreme rainfall events in South East South America (SESA), at multiple temporal scales (sub-seasonal to seasonal). Dissertation Topics In Law? I use an approach known as weather-within-climate that identifies persistent weather types through cluster analysis to describe climate events with particular characteristics. I analyze the relationship between these synoptic circulation types and extratropical cyclones, meso-scale convective systems and fruits of sorrow essay, enhanced moisture advection events (e.g., low-level jets or atmospheric rivers), also exploring different sources of potential predictability (e.g., El Nino-Southern Oscillations, Southern Annular Mode, Atlantic Meridional Mode, Southern Atlantic Dipole, Madden-Jullian Oscillations and the South Atlantic Convergence Zone behavior) for these events at different temporal scales.
I have found that these weather types are not only useful to understand the physical mechanisms and identify potential predictors related to extreme events, but that they are “sensitive” to cross-timescale interactions between the different climate drivers. This led me to explore the impact of the so-called Cross-timescale Interference Conjecture on extreme rainfall events. My analysis indicates that considering cross-timescale interactions increases extreme events’ seasonal predictability in approximately 50%-70% with respect to help a personal statement, the more traditional approach. Using these ideas I was able to design and fruits of sorrow essay, evaluate a new methodology that is able to produce subseasonal-to-seasonal extreme rainfall scenarios”, providing not only skillful climate information about essay on the history, how many extreme events to expect in SESA for the next season, but also about how, when and where are they expected to occur.

The Sea Surface Temperature (SST) variability is governed mainly by air–sea or surface heat fluxes, subsurface processes including Ekman pumping, intense tidal mixing, and lateral advection. All oceanic and atmospheric forcing determines the of sorrow, variability of SST. The Indonesian sea surface temperature are influenced by many oceanic and atmospheric forcing across different timescales, which consist of tides, Indo-Australian monsoon, El Nino-Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD), and essay on chronic disease, the Indonesian Throughflow. They are located at the pathway of prominent tropical atmosphere phenomena such as the Madden-Julian Oscillation (MJO), which is identified as convective and subsidence cells along the equator that propagate eastward from the Indian to Pacific Ocean. The seasonal forcing is the largest contributor to SST variability in the Indonesian Seas, and the combined seasonal and semi-annual variability can only explain. 70% of total SST variances in Indonesian Seas. The remaining. 30% of the SST variability has not been studied, and we suspect that it is fruits of sorrow essay, attributed to intraseasonal and interannual variation.
My study particularly focuses on malthus's essay principle of population discussed the tendency, describing the SST characteristics at intraseasonal timescales (20-90 days) over of sorrow essay the Indonesian Seas by considering plausible governing processes such as atmospheric and help me write a personal, oceanic motions and their corresponding to the air-sea interaction. The objective of my study is to examine intraseasonal SST variability of the Indonesian seas (Indonesian maritime continent), specifically to understand the sea-air interaction, coupling of the ocean and atmosphere associated with the MJO dynamics, which we argue is one of the primary drivers for SST variability at intraseasonal timescales in some area of the Indonesian Seas.

My primary research focuses on fruits essay, plants’ physiological response to increasing air temperatures. Most of on chronic obstructive pulmonary disease, my work is conducted in the Hudson Highlands Region of New York State, where proximate causes of climate change, such as insect outbreaks, severe droughts, environmental disturbances such as forest clearings, and intense deer browsing have resulted in the mortality of dominant tree species (oaks), impacting long-term biomass, carbon dynamics, and carbon storage capacity in northeastern forests. However, one of the most important threats to carbon storage capacity in the region includes plant community shifts via climate change.
A study published in 2008 by collaborators at Black Rock Forest summarized changes in forest composition over the last 76 years. They found that three northern ranged species were extirpated from the forest and fruits of sorrow, eleven southern-ranged or non-native species had migrated in naturally or anthropogenically.

The West African Monsoon is one of the major monsoon systems on the planet, delivering the totality of literary essay rubric, rainfall to the Sahel region of Africa during a few summer months. Fruits? This monsoon system has demonstrated considerable variability on a number of timescales ranging from sub-seasonal to dissertation topics in law, interannual, decadal, and fruits of sorrow, even millennial.
Indeed, both the spatial extent and magnitude of the observed rainfall shift during the 20th Century in this region was unseen anywhere else in dissertation topics, the world. Much of the essay, variability on seasonal to decadal timescales has been attributed to literary school, forcing by the global oceans, which drive anomalously weak or strong monsoon responses. However, the physical mechanisms which link sea surface temperature (SST) anomalies across the various basins to precipitation changes over land are not fully understood, nor is the interplay between competing anomalies and their resulting effects. My dissertation aims to address some of these research gaps using a blend of observations, theories, and modeling. Some of the ways in which I have been re-examining the role of the of sorrow essay, global oceans on Sahel rainfall variability are in using a moisture budget framework and idealized SST experiments to identify the atmospheric signatures that are consistent with precipitation change. The improved understanding of the effects of SSTs on Sahel rainfall variability have large implications for policy and decision-making in the region.

The first half of my thesis focuses on the shallow portion of the seismogenic zone at the Japan Trench where the 2011 M w 9.1 Tohoku-Oki earthquake slipped to the surface and caused a large tsunami, leading to the disaster at the Fukushima nuclear power plant. A year after the earthquake, an ocean drilling expedition sampled the of sorrow, fault zone that slipped during the Tohoku-Oki earthquake.
I have used trace element geochemistry to essay pulmonary disease, develop a detailed stratigraphy of the plate boundary fault zone, which gives insight into the distribution of fruits, deformation in this region. The degree of localization of slip can have significant implications for the stress state required for topics in law this shallow slip. I am also developing a biomarker thermal maturity indicator (using alkenones and n -alkanes) to fruits essay, determine whether faults in the decollement region have experienced a significant temperature rise (inferred to be the result of frictional heating). This allows us to determine which faults inferred from the stratigraphy were likely to dissertation, have slipped seismically. Through a series of hydrous pyrolysis experiments, I also constrain the kinetics of the biomarker thermal maturation to estimate the temperature rise on these seismic faults. This allows us to put constraints on fruits essay, the maximum earthquake each of these faults may have experienced. The second half of my thesis focuses on the effect of temperature changes on the frictional behavior of subducting sediments at of tango, the upper limit of the fruits essay, seismogenic zone.
I will investigate the effect of short-duration pulses of hot fluid onto fault surfaces from nearby fault zones. This will give insight into the dynamic frictional behavior that can be important for our understanding of obstructive, aftershock sequences. Fruits? I will also investigate the frictional behavior of subducting sediments with varying amounts of carbonate, a significant input to the sedimentary budget of subduction zones. Carbonate material tends to disease, begin deforming plastically at shallower conditions than silicate rock. However, carbonate-rich sediment has been observed to demonstrate unstable slip behavior over a wider range of conditions than more clay-rich sediment.

How do morphological and molecular evolution relate to fruits of sorrow, climate, and can characters and character changes be local paleoenvironmental proxies? Do ancient biomolecules, including DNA and protein sequences, agree with morphological phylogenetic data? Some projects: I am expanding the Assembling the Tree of Life project Mammalia dataset, adding taxa to test the hypothesis that some of the SANUs are related to African mammals while others are related to history, Holarctic ungulates.

I find that thermally controlled slippery patches at the ice sheet base can migrate downstream over time. Convergence produced by the gradient in basal slip around these patches produces uplift within the ice sheet.

My research interest is to study modern and past ocean circulation using Nd isotopes and concentration. It consists of the following components: 1. The high Nd isotope ratios of North Pacific Deep Water (NPDW, ?Nd = -4) have been difficult to reconcile with the inputs as reflected in surface waters (e.g. Jones et al.
EPSL 2008). An additional volcanic component has been suggested. In order to constrain the sources of Nd in the North Pacific, samples from the fruits essay, INOPEX Cruise (2009) have been analyzed for Nd isotopes. Below 2500m in malthus's on the discussed of humans, samples from the Aleutians-Kamchatka and fruits essay, East Asia margins, the ?Nd values are convergent at. -3.6, consistent with NPDW. However, samples above 2500m from Aleutians-Kamchatka show higher ?Nd than corresponding depths near East Asia, consistent with higher volcanic contributions near the Aleutians-Kamchatka. In the shallowest 500m the ?Nd trends to malthus's discussed the tendency, more positive values toward the surface (to -1.5) near the Aleutians-Kamchatka, and toward lower values near East Asia (to -4.6), also consistent with volcanic contributions at Aleutians-Kamchatka. The highest ?Nd at Aleutians-Kamchatka coincides with a previously reported Fe concentration maximum, interpreted as Fe mobilization from reduced marginal sediments (Lam and Bishop GRL 2008), which may also be a means of mobilizing REE.
2. Over the past several years, studies have increasingly focused on essay, the potential of external addition of Nd along water mass transport paths (for example through “boundary exchange” with particulates or addition from groundwaters), thus challenging the idea that Nd isotopes behave “quasi-conservatively” in the oceans. The SW Atlantic, with the major water masses involved in the AMOC (southward flowing NADW, northward flowing AAIW and AABW), is arguably the best place on on chronic obstructive disease, Earth to evaluate how well Nd isotopes trace water mass mixing, in of sorrow essay, order to clarify its value for following the dissertation in law, AMOC through time. We will report Nd isotope ratios of seawater collected on the SW Atlantic meridional transect of the of sorrow essay, NIOZ West Atlantic GEOTRACES Cruise Leg 3 (RRS James Cook 057), which sampled seawater profiles and the sediment surface at 18 stations between 0-50°S. Most stations are sampled in the open ocean, providing a test of whether Nd isotopes show quasi-conservative mixing systematics away from continental margins. The cruise section also provides several opportunities to test the potential effects of external Nd input. 3. Dissertation Topics? The modern Southern Ocean has significant input from NADW, which is essay, reflected in Nd isotope compositions of the Southern Ocean, and on chronic pulmonary, when the essay, Atlantic meridional ocean circulation weakens, so will the help a personal, North Atlantic signal. Thus, present and paleo-records of the water mass distribution in the Southern Ocean will help to understand the changes of of sorrow essay, ocean circulation.

The Late Pleistocene Evolution of the Black Sea. The Black Sea is a large, deep, and semi-enclosed body of water that lies at the interior of a series of basins connected to the Mediterranean Sea via two shallow sills characterized by an estuarine-type circulation. This hydrologic setting changed in the past. Over the last 3 million years, the Black Sea alternated between two environments: a freshwater lake and a brackish-to-marine basin. The factor that controlled the preferential state is the form of the topics in law, connection with the Mediterranean Sea.
The entry of salt water is limited by fruits of sorrow essay the height of the global sea level relative to the threshold depth of the sill in the Bosphorus portal. The last time the Black Sea connected to essay on the of humans, the Mediterranean occurred approximately 7,150 years ago as a consequence of the rising global sea level from deglaciation. Essay? This led to literary rubric school, large changes in the basin which include salinization, sapropel deposition, anoxia, and fauna turnover. Fruits Of Sorrow? This event is clearly seen in both shelf and statement, slope cores. Prior to the connection, the Black Sea remained very fresh and the bottom waters were more oxygenated.
Turnover occurred at times the surface waters became dense enough to break the stratification. During the last glacial maximum, the Black Sea sediments have a series of sulfide spots implying that turnover was reduced. These spots disappeared when a series of of sorrow, meltwater pulses appear in the cores, which have a distinct brownish color and rubric middle school, record hyper-pycnal floods. Plumes of freshwater brought oxygen to the black sea and hence, formation of iron sulfide did not occur. I am studying the series of these events, how they are reported in the sediments, how one dates them, and the connections between the shelf and the slope cores. I am also thinking about how these events in essay, the Black Sea connect to statement, global and the possible implications.
