In the SSM/I image it is seen, that the SAR frame is entirely placed into the ice.
This is also seen in the SAR image, where there are no obvious open water
areas present.
The homogeneous area in the left hand side is a consolidated ice area.
In the central part, some wavy dark patterns are seen, and this is probably
new ice or open water. The wind at Jan Mayen is low (5m/s) [NMI,
1993], and the open water can therefore have a dark signature. By comparing
the SSM/I images in the last few days it is seen, that the ice in this part
of the image is formed during the last 2-3 days. It is therefore difficult to
determine if the dark areas are open water or new ice.
In the right hand side of the image, the patterns appears more grey than in the
central part.
This can be caused by a mixture of pancake ice and open water.
