Graduate Opportunity - Cosmogenic nuclide applications - Purdue University - PRIME Lab
The in situ cosmogenic 14C laboratory at Purdue University's PRIME Lab is seeking a motivated new M.S. student interested in working with in situ cosmogenic 14C (in situ 14C) for surficial process and Quaternary geologic studies. In situ 14C is produced by cosmic rays incident on terrestrial materials in a manner similar to other commonly measured in situ cosmogenic nuclides such as 10Be or 26Al. However, its significantly shorter half-life enables one to explore surface processes in ways previously unavailable using only long-lived or stable cosmogenic nuclides.
In particular, we have funding for a student interested applying in situ 14C in concert with 10Be and 26Al to study Holocene and late Pleistocene glacial chronologies in East Antarctica, as part of a broader, multinational, multi-investigator project to reconstruct and predict the response of the Antarctic Ice Sheet to climate change - a major challenge facing the Earth Science community. In this project we will test and improve ice sheet models by comparing model predictions of past ice extent to the geologic record in Dronning Maud Land, Antarctica. This innovative project will collect key geologic data from mountains called nunataks that extend above current and former ice levels that can be used as "dipsticks" to reconstruct changes in ice elevation that will be used to improve the models. The end result will be both much better knowledge of past three-dimensional changes of the Antarctic Ice Sheet, and improved models that allow for more accurate simulations of potenti
al future changes in the ice sheet.
Research experience is desirable, and applicants must have strong quantitative and writing skills. Interested applicants should send a CV and a brief summary of relevant field and/or laboratory experience to Dr. Nat Lifton at nlifton@purdue.edu (http://www.eaps.purdue.edu/people/faculty-pages/lifton.html). Applications received by August 1, 2016 will receive preferred consideration. See http://www.eaps.purdue.edu/for_students/graduate/grad_admissions.html for details on the application process.
Purdue is a major research-extensive university in north-central Indiana that is well known internationally as a center for innovative research involving cosmogenic nuclide methods. Our research community includes several faculty and a highly productive group of graduate students across earth sciences and physics. PRIME Lab (the Purdue Rare Isotope Measurement Laboratory) is a dedicated national accelerator mass spectrometry (AMS) facility funded by NSF, NASA and NIH. Purdue University is an Equal Opportunity/Equal Access/Affirmative Action employer fully committed to achieving a diverse student body.
