The Arctic sea ice cover is in decline. The areal extent of the ice cover has been decreasing
for the past few decades at an accelerating rate. Evidence also points to a decrease in sea …

Marginal ice zones (MIZs) are qualitatively distinct sea-ice-covered areas that play a critical
role in the interaction between the polar oceans and the broader Earth system. MIZ regions …

In order to explore changes and trends in the timing of Arctic sea ice melt onset and
freezeup, and therefore melt season length, we developed a method that obtains this …

There is an ongoing shift in the Arctic sea ice cover from multiyear ice to seasonal ice. Here
we examine the impact of this shift on sea ice albedo. Our analysis of observations from four …

The extent of snow cover and sea ice in the Northern Hemispherehas declined since 1979,
coincident with hemispheric warming and indicative of a positive feedback of surface …

Over the past few decades the Arctic sea ice cover has decreased in areal extent. This has
altered the solar radiation forcing on the Arctic atmosphere‐ice‐ocean system by decreasing …

The summer extent of the Arctic sea ice cover, widely recognized as an indicator of climate
change, has been declining for the past few decades reaching a record minimum in …

The extent of Arctic perennial sea ice, the year‐round ice cover, was significantly reduced
between March 2005 and March 2007 by 1.08× 106 km2, a 23% loss from 4.69× 106 km2 to …

Abstract The area of Arctic September sea ice has diminished from about 7 million km 2 in
the 1990s to less than 5 million km 2 in five of the past seven years, with a record minimum …

The timing of melt onset affects the surface energy uptake throughout the melt season. Yet
the processes triggering melt and causing its large interannual variability are not well …
