SummaryDFD is developing a near-real-time service to support sea ice and iceberg monitoring at the Antarctic Peninsula in close cooperation with EOC’s Maritime Security Lab in Bremen and Neustrelitz. Data reception, processing and product delivery are to take place at the DLR O’Higgins Station. In support of the test and validation of the newly developed products and services focusing on the Antarctic Peninsula area, high resolution TerraSAR-X radar data will be used for sea ice detection and mapping including the identification of ice conditions, icebergs, ice limits and ice floes areas. Therefore, near real time data are needed on-time and on-site during the planned campaigns being available to the mentioned DLR staff. The processors were developed by the Maritime Security Lab in Bremen for wind/wave, oil spill and iceberg detection as well as for sea ice classification. These existing algorithms are tailored for European and Arctic conditions. They are in the validation phase at the moment and can be used soon. The ice regimes in the Antarctic differ from those in the Arctic. Therefore the software needs to be adapted and has to be tested under realistic conditions. In addition, a near realtime service will be implemented at GARS O’Higgins in order to receive and produce TerraSAR-X products on site which needs to be tested under realistic conditions. Beside the comprehensive test and validation of the NRT service and the generated products for the Antarctic Peninsula area the objective of the proposal is - as mentioned - to also use the data for monitoring sea ice conditions, icebergs, ice limits and ice floes in the area of interest during the whole period of the project. In addition the differences in Arctic and Antarctic regimes will be further investigated, in particular with respect to the utilization of satellite data. With regard to future satellite missions, this work could also be used for the long-term assessment of ice conditions at the Antarctic Peninsula and its change over time.
