*3 Ph.D. positions in paleoclimate modeling*
- under the condition of job release-

In the framework of the new Priority Programme SPP 1266 "Integrated Analysis of Interglacial Climate Dynamics (INTERDYNAMIK)" funded by the German Research Foundation (DFG), the Geosystem Modeling Group at the Department of Geosciences, University of Bremen, Germany, has three openings for Ph.D. students in the area of paleoclimate modeling.

*Position 1* (reference number A 118/07):* *The Ph.D. project aims at investigating climate-vegetation dynamics during Late Quaternary interglacial periods. The successful candidate will carry out numerical simulations with the comprehensive global climate model CCSM coupled to
vegetation and ice-sheet models in a parallel supercomputing environment. The main objective of the work is to identify and analyze differences between individual interglacials and to explore the importance of feedbacks between land cover and climate. Results will provide insight into potential future climate system change associated with anthropogenic carbon dioxide inputs. The project is a collaborative effort between the University of Bremen, the Potsdam Institute for Climate Impact Research (PIK), the Alfred Wegener Institute for Polar and Marine Research (Bremerhaven) and the Free University Berlin. *Deadline for application is 26 October, 2007*.

*Position 2* (reference number A 119/07): The Ph.D. project aims at investigating the variability of the southern hemisphere westerlies during the past 10,000 years. The successful candidate will carry out transient simulations with the comprehensive global climate model CCSM in a parallel
supercomputing environment. The main objective of the work is to identify the major forcing mechanisms that determine variability of the southern hemisphere westerlies and to improve understanding of the role of the westerly wind belt in shaping global climate change. The project is a collaborative effort between the University of Bremen, the Geoforschungszentrum Potsdam and the Alfred Wegener Institute for Polar and Marine Research (Bremerhaven). *Deadline for application is 26 October, 2007 *.

*Position 3* (reference number A 120/07): The Ph.D. project aims at investigating the variability of the Arctic ocean-sea ice system during the Holocene. The successful candidate will carry out computer simulations with a regional numerical model of the Arctic Ocean. The main objective of
the work is to assess the role of the Arctic Ocean in shaping past and future climate changes. The project is a collaborative effort between the University of Bremen, the Alfred Wegener Institute for Polar and Marine Research (Bremerhaven) and the IFM-GEOMAR (Kiel). *Deadline for
application is 4 October, 2007*.

For all positions, applicants must have a Diploma or M.Sc. in *physics*, *Earth sciences* or a related discipline and enjoy working in an international and interdisciplinary team. Experience in numerical modeling and scientific computation (UNIX/LINUX, FORTRAN) is helpful. Good English language skills are required.

Salary will be according to the German civil service remuneration system E13 TV-L/2. All appointments are initially for two years with possible extension to three years.

As the University of Bremen intends to increase the proportion of female employees in science, women are particularly encouraged to apply.

In case of equal personal aptitudes and qualification, disabled persons will be given priority.
