Abstract : Digital analysis of AVHRR (Advanced Very High Resolution Radiometer) thermal infrared band imagery has yielded sea ice surface temperatures which were used to calculate daily net surface heat loss and accompanying ice production and salt rejection from strips of thin ice within the Chukchi Polynya. These results are in agreement with published estimates of heat loss, ice production and salt rejection from the open water surface of the St. Lawrence Island polynya and of Whaler's Bay north of Svalbard and from thin ice in the central Arctic.
