Our knowledge of the dwindling sea ice coverage in the Arctic Ocean comes mostly through satellites, which since 1979 have imaged the sea ice from above. The University of Washington's Pan-Arctic Ice Ocean and Modeling System, or PIOMAS, is a leading tool for gauging the thickness of that ice. Until now that system has gone back […]
A new study provides a 110-year record of the total volume of Arctic sea ice, using early US ships' voyages to verify the earlier part of the record. The current sea ice volume and rate of loss are unprecedented in the 110-year record.
