SASIEv.1: a framework for seasonal and multi-centennial Arctic sea ice emulation [PDF]

Geoscientific Model Development
The high computational expense of complex climate models and their tendency to underestimate observational records of Arctic sea ice sensitivity to anthropogenic forcers challenge our ability to assess the magnitude of forcing that will cause Arctic sea ...

Toward a marginal Arctic sea ice cover: changes to freezing, melting and dynamics [PDF]

The Cryosphere
As the summer Arctic sea ice extent has retreated, the marginal ice zone (MIZ) has been widening. The MIZ is defined as the region of the ice cover that is influenced by waves and for convenience here is defined as the region of the ice cover between sea

Oxygen fluxes beneath Arctic land-fast ice and pack ice: towards estimates of ice productivity [PDF]

Polar Biology, 2018
Sea-ice ecosystems are among the most extensive of Earth’s habitats; yet its autotrophic and heterotrophic activities remain poorly constrained. We employed the in situ aquatic eddy-covariance (AEC) O2 flux method and laboratory incubation techniques (H14CO3−, [3H] thymidine and [3H] leucine) to assess productivity in Arctic sea-ice using different ...

Arctic Ocean surface geostrophic circulation 2003–2014 [PDF]

The Cryosphere, 2017
Monitoring the surface circulation of the ice-covered Arctic Ocean is generally limited in space, time or both. We present a new 12-year record of geostrophic currents at monthly resolution in the ice-covered and ice-free Arctic Ocean derived from ...

Algal Hot Spots in a Changing Arctic Ocean: Sea-Ice Ridges and the Snow-Ice Interface

Frontiers in Marine Science, 2018
During the N-ICE2015 drift expedition north-west of Svalbard, we observed the establishment and development of algal communities in first-year ice (FYI) ridges and at the snow-ice interface.

sea-ice arching and multiple flow States of Arctic pack ice [PDF]

Annals of Glaciology, 2006
AbstractFlow of ice through narrow channels is Significantly affected by the amount of Shear Strength in plastic rheologies used in Sea-ice models as well as in reality. When thermodynamics is added to this problem, the capability of multiple flow States for the Same forcing through narrow passages arises.

The Arctic Summer Cloud Ocean Study (ASCOS): overview and experimental design [PDF]

Atmospheric Chemistry and Physics, 2014
The climate in the Arctic is changing faster than anywhere else on earth. Poorly understood feedback processes relating to Arctic clouds and aerosol–cloud interactions contribute to a poor understanding of the present changes in the Arctic climate system,

Low Density of Top Predators (Seabirds and Marine Mammals) in the High Arctic Pack Ice

Scientifica, 2016
The at-sea distribution of top predators, seabirds and marine mammals, was determined in the high Arctic pack ice on board the icebreaker RV Polarstern in July to September 2014. In total, 1,620 transect counts were realised, lasting 30 min each.

The effect of sea-ice loss on beluga whales (Delphinapterus leucas) in West Greenland [PDF]

, 2010
An aerial survey was conducted to estimate the abundance of belugas (Delphinapterus leucas) on their wintering ground in West Greenland in March–April 2006 and 2008.

Leads in Arctic pack ice enable early phytoplankton blooms below snow-covered sea ice [PDF]

, 2017
The Arctic icescape is rapidly transforming from a thicker multiyear ice cover to a thinner and largely seasonal first-year ice cover with significant consequences for Arctic primary production.
