Interior of the Arctic pack-ice
This
ERS-1 SAR image has been acquired on 22-12-1993 and it is an example of 95-100%
concentration of multiyear ice combined with some firstyear ice and refrozen
leads at 84ºN and 65ºE (see the location of the SAR
image ). This is near the northernmost limit where ERS SAR coverage is possible.
The image is obtained in late summer and many of the floes can have been covered
with melt water. The SAR signature of multiyear ice in late summer is often
darker compared with winter images. The dark signatures in the leads indicate
young ice with smooth surface.
