This report is a summary of achievements during Phase III of Contract N00014-89-C-0014 and a reduced version of the progress report issued at the end of summer 1989. The latest versions of two submitted papers are included as appendices. In May 1987 a collaborative experiment took place in the Arctic Ocean. A British submarine and two remote sensing aircraft co-operated in concurrent profiling and imaging of the upper and lower sea ice surfaces along the same track. The submarine was equipped with a 780 Upward-looking Sonar System (narrow beam, 48 kHz), feeding chart and digital recorders, and an EDO western 602 Sidescan Sonar towfish (100 kHz) feeding an EDO 706 sidescan mapping system. The two remote sensing aircraft comprised: A. A NASA P-3A equipped with: Advanced Multichannel Microwave Radiometer (AMMR) with 37GHz and 18GHz dual polarised channels and 21GHz vertically polarised channel, Electrically Scanning Microwave Radiometer (ESMR) operating at 19GHz, Airborne Oceanographic Lidar (AOL), PRT-5 infra-red radiometer, aerial cameras and video; A Cessna Conquest equipped with: the Intera STAR-2 X-band HH-polarised synthetic aperture radar (SAR), giving a 63km swath width.
