------------------------------------

The GeoForschungsZentrum Potsdam (GFZ) invites applications for seven
positions in geosciences, engineering, and information technology in the
project SEAL - "Sea Level Change: An Integrated Approach to its
Quantification"

SEAL is a large-scale research project of the Hermann von Helmholtz
Association of German Research Centres (HGF) focusing on an integrated
strategy for quantifying sea level changes on various space and time
scales. The project, co-ordinated by the GeoForschungsZentrum Potsdam
(GFZ), uses the interdisciplinary expertise of the cooperating HGF
Research Centres Alfred Wegener Institute for Polar and Marine Research
(AWI), GeoForschungsZentrum Potsdam (GFZ), and GKSS Research Centre
Geesthacht (GKSS). The project's major tasks are sea level observation,
glacial isostasy, ice mass transfer, and ocean modeling.

The successful candidates are expected to work in interdisciplinary
cooperation between the participating project sections and the different
project locations. The specific fields of cooperation are indicated in
brackets respectively.
