IceSAR: April flights

From Jørgen Dall and Anders Kusk (DTU Space), Kangerlussuaq, 22 April From Thursday to Saturday (19–21 April), a Twin Otter aircraft was flown over the K-transect, a line starting at the Russell outlet glacier near Kangerlussuaq and stretching some 150 km into the ice sheet. The Twin Otter carried a radar called POLARIS, developed for ESA by the Technical University of Denmark. Asa Tania’s earlier post mentioned, the objective was to assess one of the secondary objectives of ESA’s Biomass Earth Explorer candidate mission: ice mapping. The direction of the antenna pattern can be steered by means of electronic beamforming, and looked to the left, to the right and straight down with...

IceSAR ready to fly in Greenland

From Tania (ESA), Kangerlussuaq, 20 April It is perhaps somewhat ironic that the P-band imaging SAR designed for forest biomass mapping on the Earth Explorer candidate mission Biomass could also provide unique information on ice sheets in the cryosphere. However, a number of scientific studies have shown that long-wavelength P-band radar images to map forest biomass, may also be highly useful to monitor ice movement on ice caps. Even more tantalisingly, since P-band radar penetrates into the snow surface much more than other radar frequencies, images from Biomass could potentially provide a glimpse of ice structures beneath the surface. So, enter ESA campaigns to test and document this potential ! This weekend,...
