SummaryIn the proposed project it is planned to extract information about sea ice drift and deformation, and about the drift of icebergs captured in sea ice. For this purpose, sequences of wide-coverage TSX images are used. The ice drift and deformation fields retrieved from the TSX imagery are compared and combined with the data of ice buoys and buoy arrays that will be deployed in the eastern Weddell Sea during a cruise of the research vessel Polarstern in austral 2014. Data of sea ice properties are gathered at different locations. The goal is to take advantage of the combination of spatially dense drift field retrievals from satellite images and high-resolution time series of drifting ice buoys, and to link ice drift patterns and ice conditions. The capability to detect icebergs will be tested with TSX dual-polarization images. To optimize the scientific output, near-real time data are provided by DLR for ship navigation, field work planning, and buoy deployment. This special provision of images helps DLR to develop and improve its near-real time service in the realm of marine security, which will be of increasing importance in the future, and which is becoming a major driver for recent and future space-borne SAR developments.
