LAII research, based primarily in Alaska, addresses global change trends, feedback processes, and effects of global change on the physical and biological environment of the Arctic. In general, snow and sea ice data products will be available as daily, eight-day, and monthly composites. The marine environment of the Arctic is an interactive system comprising the water, ice, air, biota, dissolved chemicals and sediments of the Arctic Ocean and its adjacent seas. OAII seeks to enhance understanding of this system and its role in climate and global change. Approximately 25 investigations used in situ measurements and satellite and aircraft remote sensing to measure and understand the mass balance of the Greenland Ice Sheet.
Data is available through investigator Web sites.
As a subgroup of the Pathfinder Program, Polar Pathfinders seeks to facilitate the comparison of parameters from different data sets. Radarsat Antarctic Mapping Project Radarsat, a satellite built by the Canadian Space Agency and launched by NASA, has acquired the first high-resolution radar image coverage of the entire Antarctic continent.
