The Polar Bear Pass wetland area on Bathurst Island (75°40'N, 98°30'W) is the second largest wetland in the Canadian High Arctic with an area of 20 x 5 km². The wetland is a mosaic of land types comprising ponds, lakes and zones of dry ground that alternate with wet areas in a range of only a few meters.

Our research at Polar Bear Pass aims to identify key surface paramaters for the quantification of energy and water fluxes at the regional scale via aerial pictures and satellite data. Methods include the operation of two automatic soil stations, high-resolution aerial photography with a kite, spectrometry and ground-penetrating radar.
