Potential source regions and processes of aerosol in the summer Arctic [PDF]
Atmospheric Chemistry and Physics, 2015 Sub-micrometer particle size distributions measured during four summer cruises of the Swedish icebreaker Oden 1991, 1996, 2001, and 2008 were combined with dimethyl sulfide gas data, back trajectories, and daily maps of pack ice cover in order to ...

Atmospheric highs drive asymmetric sea ice drift during lead opening from Point Barrow [PDF]
The Cryosphere, 2023 Throughout winter, the winds of migrating weather systems drive the recurrent opening of sea ice leads from Alaska's northernmost headland, Point Barrow.

Hydraulic controls of summer Arctic pack ice albedo [PDF]
Journal of Geophysical Research: Oceans, 2004 Linkages between albedo, surface morphology, melt pond distribution, and properties of first‐year and multiyear sea ice have been studied at two field sites in the North American Arctic between 1998 and 2001. It is shown that summer sea‐ice albedo depends critically on surface melt‐pond hydrology, controlled by melt rate, ice permeability, and ...

A Study of the M-2 Tide in the Ice-Covered Arctic Ocean [PDF]
Modeling, Identification and Control, 1981 A model to study M2 tide propagation in the Arctic Ocean based on the equation of motion of the water and the pack ice, is considered. The mechanics of the ice floe interaction is described by the non-linear viscous constitutive loaw.

Relating arctic pack ice stress and deformation under winter conditions [PDF]
Journal of Geophysical Research: Oceans, 2002 Together, thermodynamic and dynamic processes determine the thickness distribution of the ice cover on polar oceans, which governs the exchange of energy between the atmosphere and the ocean. Key to the dynamic processes is the mechanical behavior of the ice cover. During the Surface Heat Budget of the Arctic Ocean (SHEBA) field experiment, we deployed

Variability and changes of Arctic sea ice draft distribution – submarine sonar measurements revisited [PDF]
The Cryosphere, 2011 Changes in the mean sea ice thickness and concentration in the Arctic are well known. However, quantitative information about changes in the ice thickness distribution and the composition of the pack ice is lacking.

A critical review of Arctic pack ice driving forces: New sources of data [PDF]
Cold Regions Science and Technology, 2017 Abstract This paper provides the details of ice loading events that can be used to further the understanding of pack ice driving forces in the Beaufort Sea. Several methods have been reviewed and employed including in situ stress measurements, loads on the Molikpaq offshore caisson, shoreline pile-up events, pile-ups and rubble fields on offshore ...

Studies of the Mass Budget of Arctic Pack-Ice Floes [PDF]
Journal of Glaciology, 1965 AbstractThe processes of melting, freezing, precipitation, evaporation and condensation were considered in the computation of the mass budget of an ice floe in the northern Chukchi Sea. It was bound that condensation and evaporation contribute negligible amounts, and that melting accounted for the largest loss from the upper surface of the floe.

Past and future interannual variability in Arctic sea ice in coupled climate models [PDF]
The Cryosphere, 2019 The diminishing Arctic sea ice pack has been widely studied, but previous research has mostly focused on time-mean changes in sea ice rather than on short-term variations that also have important physical and societal consequences.

On the future navigability of Arctic sea routes: high-resolution projections of the Arctic Ocean and sea ice [PDF]
, 2017 The rapid Arctic summer sea ice reduction in the last decade has lead to debates in the maritime industries on the possibility of an increase in cargo transportation in the region.
