The Alfred Wegener Institute for Polar and Marine Research (AWI) invites
applications for two postdoc positions (Reference Numbers 52/POL and
53/MAR) and one Ph.D. position (Reference Number 54/POL) as part of a
Federal Ministry of Education and Research-funded project "Variation of
Freshwater Transport in the Arctic."
Background
Large river runoff and sea ice melt cause an enormously stable
stratification of the Arctic Ocean. The circulation and budget of the
huge surplus of freshwater in the upper Arctic Ocean are recognized to
have a considerable effect on the Atlantic Meridional Overturning
Circulation. Changes of the latter are expected to have the potential to
cause climate change. Understanding the involved mechanisms and the
dynamics that regulate the release of the arctic freshwater to the deep
convection sites of the North Atlantic requires a combination of
sustained observation of motion and properties of the Arctic Ocean upper
layers and their exchange with the North Atlantic with the numerical
simulations of the arctic and North Atlantic ocean-sea ice system. The
successful applicants will become members of a team that combines
observational and numerical investigations of Arctic Ocean and sea ice
variability.
One Postdoc position (Reference Number 52/POL) will conduct and analyze
observations of velocity and hydrography from newly developed
ice-tethered platforms with automated systems as well as tracer data.
The observations are part of the International Arctic Ocean Observing
System (iAOOS) program. Applicants should be enthusiastic and hold a
Ph.D. degree in physical oceanography or a related discipline.
Applicants should also have experience from cruises and/or oceanographic
data analysis.
The second Postdoc position (Reference Number 53/MAR) will conduct and
analyze numerical simulations with the North Atlantic-Arctic Ocean-Sea
Ice Model (NAOSIM) hierarchy of the AWI. This includes hindcast
simulations of the variability over the previous century as well as
future scenario calculations. Applicants should be enthusiastic and hold
a Ph.D. degree in physical oceanography or a related discipline.
Applicants should also have experience in numerical modelling, good
mathematical skills, and experience with FORTRAN/Unix. Knowledge of
statistical data analysis would be advantageous.
The Ph.D. student position (Reference Number 54/POL) will investigate
the past and future developments of the freshwater, ice, and snow
balances of the Arctic Ocean. Close cooperation with members of the
existing arctic circulation group is expected. Candidates must be
willing to participate in scientific cruises in the Arctic. Applicants
should have completed university studies (Masters degree or equivalent)
in physics, physical oceanography, meteorology, or mathematics and
should have a deep interest in understanding the high latitude climate
system.

reports along with the position reference number to:
