SummaryIn the proposed project it is planned to extract information on sea ice deformation,drift patterns, the occurrence of leads, as well as the state of short-term seasonal variations in the snow cover. This information extracted from near realtime TerraSAR-X imagery received on board of research vessel Polarstern shall be used to plan in-situ and airborne observations made over sea ice during the Polarstern cruise ANT-XXIX/7 between August and October 2013. In-situ and airborne observations are carried out e.g. through a so called EM BIRD, capable of measuring sea ice topography and sea ice thickness, and a Remotely Operated Vehicle (ROV) to carry out under-ice observations. The combination of polarimetric SAR information with in-situ and airborne data will enable us to upscale the field measurments and to draw conclusions on the role of sea ice in krill biology and ecophysiology with emphasis on larval krill during winter.

Besides its scientific impact in the field of marine biology will the outcomes of the SAR near realtime application allow DLR further improvement and development of its services in the realm of marine security, which will be of increasing importance in the future, and which is going to become a major driver for recent and future spaceborne SAR developments.
