Sea ice thickness measurements collected during the LOMROG 2007 and 2009 expeditions
According to scientific measurements, the Arctic sea ice extent has declined dramatically over the past thirty years, with the most extreme decline seen in the summer melt season. Other observations indicate that the sea ice has become thinner and perennial ice less widely distributed. The processes...
