Topography-albedo feedback reinforces the transition to a younger Arctic ice pack
Over the past few decades, the Arctic sea ice cover has rapidly shifted from consisting largely of thicker multiyear ice to predominantly thinner first-year ice. While ice-albedo feedback and reductions in overall ice extent have received a great deal of

Spatial and Temporal Variations in the Extent and Thickness of Arctic Landfast Ice
Analyses of landfast ice in Arctic coastal areas provide a comprehensive understanding of the variations in Arctic sea ice and generate data for studies on the utilization of the Arctic passages.

Vertical profiling of aerosol particles and trace gases over the central Arctic Ocean during summer [PDF]
Unique measurements of vertical size-resolved aerosol particle concentrations, trace gas concentrations and meteorological data were obtained during the Arctic Summer Cloud Ocean Study (ASCOS, www.ascos.se), an International Polar Year project aimed at ...

The number and distribution of polar bears in the western Barents Sea
Polar bears have experienced a rapid loss of sea-ice habitat in the Barents Sea. Monitoring this subpopulation focuses on the effects on polar bear demography.

Winter sea ice export from the Laptev Sea preconditions the local summer sea ice cover and fast ice decay [PDF]
Ice retreat in the eastern Eurasian Arctic is a consequence of atmospheric and oceanic processes and regional feedback mechanisms acting on the ice cover, both in winter and summer.

Transition in the fractal geometry of Arctic melt ponds [PDF]
During the Arctic melt season, the sea ice surface undergoes a remarkable transformation from vast expanses of snow covered ice to complex mosaics of ice and melt ponds.

Regime-dependence when constraining a sea ice model with observations: lessons from a single-column perspective [PDF]
A substantial body of work has explored the use of sea ice concentration (SIC) and sea ice thickness (SIT) observations to initialize modeled estimates of the unobserved Arctic sea ice state via data assimilation (DA).

The summer aerosol in the central Arctic 1991–2008: did it change or not? [PDF]
In the course of global warming dramatic changes are taking place in the Arctic and boreal environments. However, physical aerosol data in from the central summer Arctic taken over the course of 18 yr from 1991 to 2008 do not show systematic year-to-year

Methanesulphonic acid (MSA, mainly derived from marine biogenic emissions) has been frequently used to estimate the marine biogenic contribution. However, there are few reports on MSA over the Arctic Ocean, especially the central Arctic Ocean.
