Infrared Scanning the Arctic Pack Ice
The U. S. Naval Oceanographic Office conducted its first infrared scanning experiment in the Arctic Basin during daylight conditions in April 1964. Many miles of coincident infrared scanner imagery and vertical photography were obtained over a large area of the Arctic Basin pack ice between North El...
