From Greenland Coast towards Jan Mayen

In February 1993 R/V "Håkon Mosby" operated in the central Greenland Sea (75ºN, 2ºW) where deep water formation occurs in winter time. SAR images from ERS-1 as well as SSM/I data were used to map the sea ice extent, especially the ice tongue Odden and the bay of open water between Odden and the main pack ice (Nordbukta). This image has been acquired by ERS-1 SAR on 13-2-1993.
(A: large multiyear-floes, B: small floes broken up by waves, C: ice edge, D: mostly open water less than 20% ice concentration, E: formation of bands of new ice in the Odden ice tounge)
The SAR stripe, which is 700 km long, was taken on February 13 and extends from the Greenland Coast at about 77ºN in a southeasterly direction into the ice tongue (see map ).

The SAR stripe covers several ice types and the open water in Nordbukta. In the interior of the ice pack most of the ice consist of large multiyear floes which can be up to several tens of kilometers in diameter. Between the large floes, young ice and firstyear ice with lower backscatter are seen in the SAR stripe.
The ice tongue was well developed in this period, as seen in the SSM/I map (see this figure ).
The figure shows the ice concentration in % from SSM/I data on the same day as the SAR stripe. The rectangle indicates the location of the SAR stripe. White areas are due to masking of land effects.
