Fellowships

 

The Schlanger Ocean Drilling Fellowship Program offers merit-based awards for outstanding graduate students to conduct research related to the International Ocean Discovery Program. The Fellowship year begins in either June or August (summer or fall semester). During the following summer, at the conclusion of the fellowship, Schlanger Fellows may attend a meeting of the U.S. Advisory Committee for Scientific Ocean Drilling (USAC) to present the initial results of their research and take part in U.S. Science Support Program-related activities.

 

The application period for the 2018-19 Schlanger Fellowship awards is now open. Applications are due on December 15, 2017. It is anticipated that at least three fellowships will be awarded. Applicants will be notified of their application outcome in early March, 2018. To apply, please read the information below and proceed to the USSSP application portal.

 

Award Information

 

Fellowship awards are $30,000 for a 12-month period and are made to the fellow’s home institution. The entire amount is intended to be applied to the research project, student stipend, tuition, benefits, and, if necessary, related travel. No part of the award is to be used to cover institutional overhead, administrative costs, or permanent equipment. Award start dates can be negotiated on an individual basis—but in general are based on the academic year and following summer.

 

Applicants are discouraged from proposing projects reliant on data from IODP expeditions that are scheduled but have not yet taken place. USSSP cannot fund projects based on prospective datasets.

 

The fellowship is open to all graduate students enrolled at U.S. institutions in full-time M.S. or Ph.D. programs. Approval of the research project by the student’s faculty advisor is necessary to begin the application process. Qualified applicants will receive consideration without regard to race, creed, sex, age or national origin.

 

 

Evaluation

 

USSSP convenes a multi-disciplinary panel of scientists to evaluate research proposals and award fellowships. The selection process is based heavily on an evaluation of research potential and quality; applicants are therefore encouraged to propose innovative and imaginative research. The number of fellowships awarded depends upon the availability of funds, but it is anticipated that three awards will be made in the next academic year. Financial need is not considered during the evaluation process.

 

 

Obligations

 

Fellows must implement their research plans over the period of the award and abide by the conditions of the award; major program changes must be approved by both USSSP and the fellow’s faculty advisor. During the award period, fellows are considered guest investigators and not employees of USSSP, IODP or associated organizations.

Assessing Deep Pacific Carbon Storage Across the Mid-Pleistocene Transition

 

Abstract
A significant reorganization of the global thermohaline ocean circulation occurred approximately 900 thousand years ago (ka) during the Mid-Pleistocene Transition (MPT). At this time, glacial atmospheric CO2 decreased and ice age cycles transitioned from 41-kyr periodicity to the 100-kyr pacing characteristic for the late Pleistocene. The deep Pacific is the global ocean’s largest carbon reservoir and as such likely played a role in CO2 storage on glacial- interglacial timescales. I propose to use the B/Ca proxy for carbonate saturation in the benthic foraminifer Cibicidoides wuellerstorfi to investigate the evolution of the deep Pacific carbon reservoir across the MPT. I will test the hypothesis that the deep Pacific played a significant role in CO2 drawdown and storage across this interval.

 

Biography
When I started my undergraduate career at Pomona College, I was excited to study anthropogenic climate change and focused on a degree in Environmental Policy. After taking an introductory geology class on Earth History with Dr. Robert Gaines, however, I realized the power of putting modern climate change in a geologic context. Fascinated by interpreting records of earth’s climatic history, I set out on a career in paleoclimatology. This brought me to my current work with Dr. Bärbel Hönisch at Columbia University. In our lab, we use boron-based proxies in foraminifera to reconstruct the geologic history of ocean acidification and the oceanic carbon cycle. I began my PhD with series of culture calibration experiments in living planktic foraminifera aimed at interpreting the ocean acidification that occurred during the Paleocene-Eocene Thermal Maximum. My work has more recently shifted to reconstructing changes to deep Atlantic Ocean carbon storage across the Mid-Pleistocene Transition. The Schlanger Fellowship will allow me to investigate whether the Deep Pacific Ocean also played a major role in carbon storage across the MPT, possibly in response to the large circulation changes observed in the Atlantic.

Survivorship and recovery of calcareous nannoplankton following the K/Pg mass extinction at “ground zero”

 

Abstract
Nannoplankton suffered a severe mass extinction at the K/Pg boundary. Although the subsequent recovery was hemispherically asynchronous, it is uncertain how it was impacted by distance to the crater. A new stratigraphically complete and expanded K/Pg section from the Chicxulub Crater presents a unique opportunity to examine survivorship and recovery patterns at “ground zero”. By comparing data from the impact site to a little-studied South Atlantic core, the proposed study will determine how severely nannoplankton recovery was delayed, where new species originated and dispersed to, and, possibly, where Cretaceous taxa survived.

 

Biography
My interest in microfossils began when I was an undergraduate at the University of Southampton (UK), where I learned how important they are to biostratigraphic and paleoenvironmental studies. To explore this application further, I worked with Dr. Samantha Gibbs for my Master’s thesis to investigate whether the cell architecture of two coccolithophore species changed during the Paleocene-Eocene Thermal Maximum (PETM). During this research project I became “addicted” to hunting for coccospheres. This motivated me to pursue a PhD so that I can better understand how these critical organisms respond to periods of environmental change. My current research focuses on calcareous nannoplankton recovery following the K/Pg mass extinction at El Kef, Tunisia. Nannoplankton recovery assemblages at this site are characterized by successions of “bloom” species, but we are uncertain about which environmental and/or ecological variables drove changes in dominant taxa. To answer this question, I am comparing my high-resolution nannofossil assemblage counts to other faunal data (i.e. foraminifera and dinoflagellate abundance counts) and geochemical proxies. I am excited about the opportunity to study nannoplankton recovery at “ground zero” during my Schlanger fellowship, and plan to compare assemblage counts from Chicxulub to those at El Kef. This will allow me to determine how environmental and ecological controls on nannoplankton recovery changed as a function of distance from the impact crater.

Uranium isotope ratios: a proxy to understand carbon burial in varying redox environments in Ocean Anoxic Event 2

 

Abstract
Increases in carbon burial (productivity) or expansion of ocean anoxia can be predicted by the occurrence of organic-rich sediments. In the sediments, uranium (U) concentration is tightly linked to carbon burial rates; on the other hand, U isotope ratios are often interpreted as an environmental redox proxy, ignoring the sedimentary geochemistry. The use of U concentration and isotope ratios is therefore inconsistent. In order to clarify the application of the U isotope proxy, I plan to study cores from the proto-North Atlantic during the Ocean Anoxic Event 2, a period of widespread organic-rich sediment deposition and variable redox conditions.

 

Biography
Growing up in Northern Maine, I enjoyed being outside with nature, but when snowstorms hit I would reach out to history books. At Bowdoin College, I studied geology and art history, which allowed me to appreciate their overlap in learning the past of earth and people, and also how chemistry can be applied in both disciplines. At Rutgers, I enjoy working on a variety of projects that observe different geological times and contexts – from samples I collected recently in the Black Sea to samples from the Cretaceous that are part of this project. Working with Dr. Silke Severmann, I am utilizing uranium and uranium isotopes to understand the processes impacting their preservation in the sediments and testing my hypotheses in a variety of geological settings.

Constraining the effect of dissolution on Pliocene West Pacific Warm Pool SSTs and the “permanent El Nino-like state”

 

Abstract
Pliocene tropical sea-surface temperatures (SSTs) are hotly debated. Foraminiferal Mg/Ca records show no long-term trend in west Pacific warm pool (WPWP) SSTs, despite higher Pliocene pCO2, and a reduced east-west SST gradient. However, modeling results and TEX86 records disagree with these findings. These discrepancies may stem from changes in dissolution (driven by Δ[CO32-]), which biased the Mg/Ca records. I propose using benthic foraminiferal B/Ca, a proxy for Δ[CO32-], to constrain the effect of dissolution on Pliocene Mg/Ca temperatures. This study would be the first to correct Mg/Ca data for time-varying dissolution. Validating Pliocene SSTs has broad significance; the WPWP is crucial for calculating climate sensitivity, and the east-west SST gradient affects climate variability.

 

Biography
Living in California, I have observed firsthand the importance of interannual climate variability, particularly El Nino-Southern Oscillation (ENSO). During my undergraduate studies at UC Santa Barbara, I worked in Jim Kennett’s lab, and fell in love with the big-picture insights that paleoceanography can give into the climate system. My master’s research with Tessa Hill at UC Davis, which focused on millennial-scale climate oscillations along the California margin, focused my interest in high-frequency climate shifts, and drove me to seek out the largest source of interannual climate variability: the tropical Pacific. Under the guidance of Christina Ravelo at UC Santa Cruz, I have developed my PhD research on the response of tropical Pacific climate variability and mean state to varying boundary conditions over the past five million years. My Schlanger Fellowship project, on Plio-Pleistocene tropical Pacific sea-surface temperatures, will help constrain climate sensitivity to pCO2, and inform my concurrent work on Pliocene ENSO. Data generated for my Schlanger project will also have implications for deep ocean circulation, which I’m looking forward to learning more about.
