The Helmholtz Centre Potsdam GFZ German Research Centre for Geosciences is
the national research centre for Earth sciences in Germany. With approx.
1180 employees, the GFZ is conducting interdisciplinary research on the
“System Earth” and the influence of humans on the planet. As a member of
the Helmholtz Association, it is part of Germany’s largest science

For Department 5 “Geomorphology, Hydrology and Paleoclimatology”, Section
5.1 “Geomorphology” we invite applications for a

PhD Student Reference No. 57/51/15 D


The aim of the research is to obtain high-resolution (i.e. decadal) records
of continental paleohydrological changes in northern, central and southern
Europe at the end of the last ice age to understand the impact of abrupt
changes in temperature on the water cycle. For this, organic-geochemical
and stable isotope-based methods (e.g. biomarkers δD and δ13C ) as well as
spatial data analysis and modelling studies are to be employed.

The research is part of the project STEEPclim (Spatiotemporal evolution of
the hydrological cycle throughout the European continent during past abrupt
climate changes), which is funded by the European Research Council, ERC,
under an ERC Consolidator Grant to Dr. Dirk Sachse. The successful
candidate will work as part of a team of several researchers in this ERC

Your tasks:


   organisation of and participation in field work to obtain sediment cores
   from lakes

   preparation of lipid extracts from sediments and analysis by gas
   chromatography-mass spectrometry (GC-

   MS) and GC-coupled isotope-ratio mass spectrometry (GC-IRMS)

   development of methods for biomarker analysis (e.g. HPLC-MS)

   evaluation, visualization, interpretation and spatial analysis of data
   and results

   Your qualifications:


   Master’s degree (or equivalent) in geosciences and/or geochemistry

   experience with organic-(geo)chemical and/or stable isotope-based
   methods and analysis (GC-MS, GC-


   experience with spatial data analysis (e.g. GIS) is an advantage

   good command of written and spoken English

   interest in research in a multidisciplinary and international environment

Start date: 01.11.2015

Duration: 1+2 years

Work hours: part-time (75%; currently 29.25 hrs/week)

Salary: EG 13 TVöD-Bund (Ost)

You can expect a diverse and challenging job in an international work
environment that is characterized by exciting research projects. The
compatibility of work and family life is of particular concern to the GFZ.
Therefore, it offers the opportunity for flexible work- hours and
workplaces. Moreover, there is a kindergarten located on the research

The GFZ is a partner of Geo.X (www.geo-x.net), and thus it is well
connected with other geoscience institutions in Potsdam und Berlin. Geo.X
forms the largest regional cluster of geoscientific expertise in Europe and
offers excellent opportunities for cooperation and development.

Please submit your application by 15.09.2015 quoting reference no. 57/51/15

documents into a single PDF file with a size of up to 3 megabytes.

Equal opportunity is an inherent part of our personnel policy. Therefore we
are particularly welcoming applications from qualified women. Severely
disabled persons will be given preferential treatment in the case of equal
