Abstract

A programme of remote sensing was undertaken in connection with two cruises by research vessels in the North-East Water polynya at the north-east corner of Greenland. Data from the Advanced Very High Resolution Radiometer (AVHRR) instrument on the NOAA satellites and Synthetic Aperature Radar (SAR) on ERS-1 was used supported by ground information collected by the research vessel, USCGC Polar Sea. Based on repeated observations of floes the motion pattern is determined, for 1992 by means of AVHRR and for 1993 by ERS-1 SAR. They confirm the anti-cyclonic movement around the Belgica Bank supported by a system of troughs surrounding the Bank. The influence of a storm is studied as well as that of the break-off of major parts of the shorefast ice that limit the polynya in the north and the south. On this basis the maintenance of the polynya during the summer is discussed and the possible influence of these barriers. -from Authors
