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 ...
PARAMETERS COMPARSION OF LEADS DETECTION IN ARCTIC SEA ICE USING CRYOSAT-2 WAVEFORM DATA
Arctic, Sea ice, Lead, Satellite altimetry
2018/5/14
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...
Rapid decline of Arctic sea ice a combination of climate change and natural variability
Rapid decline Arctic sea ice climate change natural variability
2017/3/30
Arctic sea ice in recent decades has declined even faster than predicted by most models of climate change. Many scientists have suspected that the trend now underway is a combination of global warming...
Arctic sea ice loss impacts beluga whale migration
Arctic sea ice loss beluga whale migration
2017/2/15
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...

Vanishing Arctic sea ice. Dogged weather systems over Greenland. Far-flung surface ice melting on the massive island.These dramatic trends and global sea-level rise are linked, according to a study co...
Warm Arctic, Cold Continents: A Common Pattern Related to Arctic Sea Ice Melt, Snow Advance, and Extreme Winter Weather
Arctic sea ice statistical model the Eurasian snow winter temperatures
2015/7/16
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...
Melting Ice:What is Happening to Arctic Sea Ice,and What Does It Mean for Us?
Melting Ice Arctic Sea Ice What Does It Mean for Us
2015/7/16
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...
On the existence of stable seasonally varying Arctic sea ice
existence stable seasonally varying Arctic sea ice
2012/2/28
Within the framework lower order thermodynamic theories for the climatic evolution of Arctic sea ice we isolate the conditions required for the existence of stable seasonally-varying ice states. This ...
The effect of Arctic sea-ice extent on the absorbed（net）solar flux at the surface, based on ISCCP-D2 cloud data for 1983–2007
Arctic sea-ice absorbed solar flux ISCCP-D2 cloud data
2010/2/1
We estimate the effect of the Arctic sea ice on the absorbed (net) solar flux using a radiative transfer model. Ice and cloud input data to the model come from satellite observations, processed by the...
The origin of sea salt in snow on Arctic sea ice and in coastal regions
sea salt snow Arctic sea ice coastal regions
2009/3/10
Snow, through its trace constituents, can have a major impact on lower tropospheric chemistry, as evidenced by ozone depletion events (ODEs) in oceanic polar areas. These ODEs are caused by the chemis...

2009/2/18
Four ice floes in the permanent arctic ice pack were instrumented during the summer of 1975. Spectral and cross-spectral analysis of the complex time series of the ice motion and of the surface winds ...
An Analysis of Arctic Sea Ice Fluctuations, 1953–77
Arctic Sea Ice Fluctuations polar cap digitized data
2009/2/13
Arctic sea ice data from the 1953–77 period are digitized onto a set of 300 monthly grids covering the polar cap. Each grid contains 1648 ice concentration points at a spacing of 1° latitude (60 n mi)...
