PhD position in luminescence dating of Antarctic beach cobbles at East Carolina University

Regina DeWitt
*PhD scholarship in Physics at East Carolina University, USA *

A full-time PhD scholarship is available in the Department of Physics at
East Carolina University (North Carolina, USA) to work on a research
project focused on surface luminescence dating of cobbles from Raised
Beaches along the Northern Antarctic Peninsula. The project starts with
the Fall 2017 semester.

Over the last two decades many of the ice shelves surrounding the
Antarctic Peninsula have catastrophically collapsed.  Although the loss
of these ice shelves does not contribute directly to rising sea levels,
they make an indirect contribution, since their loss is thought to lead
to faster flow rates and faster mass loss among the glaciers that are
feeding them. As a result of the mass loss, GPS measurements of the last
20 years show that the land across the Antarctic Peninsula has been
rising faster. The purpose of this project is to determine how modern
uplift rates compare to average uplift rates across the Antarctic
Peninsula over the last ~5,000 years.  We will reconstruct past sea
levels using optically stimulated luminescence (OSL) to date a series of
raised beaches along the eastern Antarctic Peninsula. This project is a
collaboration of the Department of Geology at the University of
California at Santa Barbara (UCSB) and the Department of Physics at East
Carolina University (ECU).

The successful candidate will apply OSL dating to cobbles from the
Antarctic Peninsula. The candidate is expected to join the UCSB field
team for 6-8 weeks in February/March 2018 and February/March 2019 to
collect samples of raised beaches along the Antarctic Peninsula. The
goal at ECU is to refine OSL surface dating of rocks (with conventional
and imaging methods), to test the influence of cobble size and rock type
on luminescence properties, and to provide ages for the collected
samples. A UCSB student will help with sample preparation. The applicant
will obtain a Ph.D. degree in Biomedical Physics.

For further discussion regarding the project, applicants are encouraged
to contact Dr. Regina DeWitt (email: [hidden email]). To be eligible
for a scholarship, applicants must be eligible to be accepted into the
Biomedical Physics Ph.D. program at ECU.
