A Radar Profile of a Multi-year Pressure Ridge Fragment
. In May 1977, impulse radar was used to profile the thickness of an ice island and the first-year sea-ice near our camp site on Narwhal Island, Alaska. At this location, a small fragment of a multi-year pressure ridge was found with good access to the ridge crest. The impulse radar system was taken...
