ENVISAT ASAR MONITORING OF POLYNYA PROCESSES AND SEA ICE PRODUCTION IN THE LAPTEV SEA

摘要: The Laptev Sea is one of the main source regions sea ice in Arctic Ocean. Most forms winter a prominent, quasi-permanent flaw lead or polynya (region open water), separating landfast from drifting ice. In 2003/2004 we have deployed two seafloor moorings polynya, equipped with sensors to continuously observe ice, water, and sediment properties. parallel, ENVISAT ASAR Wide Swath Mode (WSM) high resolution Image Product (IMP) Alternating Polarization (APP) scenes been ordered monitor processes formation throughout winter. Here present preliminary assessment SAR weather data. Numerous different features break-up characteristic for stages fast development are qualitatively identified discussed. These affect both production water mass modification as well inclusion transport Sea.
