SummaryA major objective the Russian-German research cooperation ‘Laptev Sea Project’ is to investigate feedback mechanisms between changing sea ice in the Russian shelf Seas, the Transpolar Drift and the Fram Strait using a combination of field observations, model studies and satellite information. To assess the accuracy of applied observational and computational data, temporally and spatially high resolution SAR satellite information is needed. This proposal presents an interdisciplinary approach that combines in-situ, air- and ship-borne observations with satellite derived sea ice information to investigate the performance of different satellite and upward looking sonar based ice drift information in the Fram Strait and in the Laptev Sea. Results will directly contribute to the question on if the increase in ice area export observed in the Fram Strait and in the Laptev Sea is associated to an increase in exported ice volume. In addition, SAR information will be used to investigate the transport and export of sediment-laden ice out of the Russian shelf seas.
