Dear List members,

Please find below an available post for a PhD position on stable carbon isotope analysis on CO2 from Antarctic ice cores.

best regards

Jochen Schmitt

 Job opportunity

within the DFG-Project COIN
“Comparison of Interglacials” we offer the following open position:

PhD student

                          with Diploma or MSc in Physics, Chemistry, Geochemistry, Geoecology or related fields


Glacier ice from polar ice sheets represents the only direct archive to retrieve information about the paleoatmosphere’s trace gas composition. Of special interest are changes in the atmospheric CO2 concentration, and especially to identify the processes driving these changes. One key information which allows to analyze the interaction between atmospheric CO2 and climate is the stable isotopic composition of CO2 (d13C).  During the last years, a new technique for d13C analysis on ice cores has been developed at AWI to provide an access to this new information. 

The goal of this PhD position is to measure a high-precision d13C record from ice core samples with this recently developed technique. Once analyzed, the d13C time series will be interpreted in close collaboration with modelers. A special focus of this work will lie on variations within Interglacials (warm periods) as these time intervals allow to pinpoint differences and similarities in global carbon cycle of the past with the current anthropogenic changes.     

Ideally, the successful applicant would already have some experience with stable isotope analysis and a basic understanding of the global carbon cycle. We offer a state-of-the-art stable isotope lab equipped with several isotope-ratio mass spectrometers with sample preparation equipment and a cold laboratory facility.

This work is part of the COIN project within the framework of the DFG focus program INTERDYNAMIK, which aims to link climate and carbon cycle modeling approaches with records from ice cores and sediments. Besides AWI, participating institutions are the Department of Geosciences at the University of Bremen and the Potsdam Institute for Climate Impact Research (PIK).

The successful candidate is expected to participate in field campaigns in polar regions for several months. The position is limited to three years, the salary is according to the German renumeration system 13/2 TVöD.
