Position Announcements (PostDoc, PhD) - Sea Ice Physics Group at Alfred Wegener Institute

Stefan Hendricks
Dear colleages,

the sea ice physics section of the Alfred Wegener Institute in Bremerhaven, Germany invites applications for 2 PostDoc positions, 1 Phd student position and 1 technician.

Position Announcements by sea ice physics section, AWI

Closing date is March 31, 2011.

PostDoc Position (reference number 29/D-KLI):

Within the project IRO (Ice-routing-optimisation – a precondition for an economical transport on the Northern Sea Way) which is sponsored by the BMWi, an existing numerical model of the coupled ocean and sea ice systems for the Arctic Ocean should be modified and installed to be used for short term predictions of the sea ice conditions within the Arctic Ocean. Therefore, an improved description of physical processes should be developed and implemented. Furthermore, model results should be validated using different observations. Results of the model calculations have to be provided promptly to other participants of the network. The results of the predictions will eventually contribute to a system to consult ships crews for a better navigation within the Arctic Ocean.

PostDoc Position (reference number 30/D-KLI):

The work will be part of the EU project SIDARUS (Sea Ice Downstream Services for Arctic and Antarctic Users and Stakeholders). The successful candidate shall analyse satellite-based sea ice thickness data and distribute the results to user groups in the Arctic and Antarctic. This requires the validation of satellite data products with aerogeophysical sea ice thickness data. In cooperation with international partners of the SIDARUS project dedicated field campaigns for satellite data validation and the intercalibration of different sea ice thickness sensors shall be planned and actively implemented.

PhD position (reference number 31/D-KLI):

The proposed research intents to investigate the influence of varying snow covers over Arctic and Antarctic sea ice on CryoSat-2 radar range retrievals. The following tasks shall be accomplished by the successful applicant:
•    Development and validation of a forward model for the simulation of radar echos for the simulation of CryoSat-2 radar echoes for snow covers of Arctic and Antarctic sea ice including the effect of surface roughness and varying physical properties
•    Interpretation of existing CryoSat-2 data with the results of the forward model
•    Generation of a thickness retrieval algorithm for Arctic and Antarctic sea ice based for CryoSat-2 data
Validation of sea ice thickness data product with airborne geophysical measurements

We also seeking a technician to extend the technical and logistical support in our sea ice related field campaigns. The successful candidate should be fluent in german language. For more information, please contact me, Prof. Rüdiger Gerdes ([hidden email]) or Dr. Marcel Nicolaus ([hidden email])

Best Wishes,
Stefan Hendricks
