Extensive sea ice covered the world's oceans during the last ice age, preventing oxygen from penetrating into deep ocean waters and complicating the relationship between oxygen and carbon, a new study...
Our knowledge of dwindling sea ice coverage in the Arctic Ocean comes mostly through satellites, which have imaged sea ice from above since 1979. The University of Washington Pan-Arctic Ice Ocean and ...
Winter ice on the surface of Antarctica's Weddell Sea sometimes has an enormous hole called a polynya. A polynya that appeared in 2016 and 2017 offered a unique opportunity for oceanographers to monit...
Leads are only a small part of the polar sea ice structure, but they play a dominant role on the turbulence exchange between the ocean and the atmosphere, they are also important factors about sea ice...
The annual migration of some beluga whales in Alaska is altered by sea ice changes in the Arctic, while other belugas do not appear to be affected.A new study led by the University of Washin...
The recent trend of increasing Antarctic sea ice extent — seemingly at odds with climate model projections can largely be explained by a natural climate fluctuation, according to a new study led by ...
An unprecedented analysis of North Pacific ocean circulation over the past 1.2 million years has found that sea ice formation in coastal regions is a key driver of deep ocean circulation, influencing ...
Sea-ice cover is the most significant feature of the polar ocean environment. Annual cycles of sea-ice cover and their interannual variations contribute significantly to changes in surface reflectivit...
The availability of real-time information on sea ice conditions in ice covered seas has always been important, not only to strategic military operations, but to the economies of those countries that b...
Physical sampling of sea ice, the water mass, and subbottom geology in the Arctic Ocean is carried out from icebreakers or temporary ice camps deployed and supported by aircraft. Here, we consider an ...
Arctic sea ice was observed to be at a new record minimum in September 2012. Following this summer minimum, northern Eurasia and much of North America experienced severe winter weather during the wint...
Satellite-borne synthetic aperture radar (SAR) data are highly valuable not only for observing the open ocean but also for monitoring seasonally or permanently ice-covered ocean regions in the Arctic,...
Sea ice has emerged as the canary in the coal mine of climate change. Its summer extent in the Arctic has decreased by about 50% over the past decade, and the Arctic Ocean has undergone a regime shift...
how is sediment transported to the seafloor along coastlines where the sea ice rarely melts? Are there distinctive characteristics of the resulting deposits that label them as accumulating in ...
As the world’s ice diminishes in the face of climate change—from the dramatic decline in Arctic sea ice, to thinning at the margins of both the Greenland and Antarctic ice sheets, to retreating mo...
