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

Future sea ice weakening amplifies wind-driven trends in surface stress and Arctic Ocean spin-up [PDF]
Nature CommunicationsArctic sea ice mediates atmosphere-ocean momentum transfer, which drives upper ocean circulation. How Arctic Ocean surface stress and velocity respond to sea ice decline and changing winds under global warming is unclear.

Sympagic Fauna in and Under Arctic Pack Ice in the Annual Sea-Ice System of the New Arctic
Frontiers in Marine Science, 2020 A strong decline and thinning of the Arctic sea-ice cover over the past five decades has been documented. The former multiyear sea-ice system has largely changed to an annual system and with it the dynamics of sea-ice transport across the Arctic Ocean ...

Culturable diversity of Arctic phytoplankton during pack ice melting [PDF]
Elementa: Science of the Anthropocene, 2020 Massive phytoplankton blooms develop at the Arctic ice edge, sometimes extending far under the pack ice. An extensive culturing effort was conducted before and during a phytoplankton bloom in Baffin Bay between April and July 2016.

Multiscale mushy layer model for Arctic marginal ice zone dynamics [PDF]
Scientific ReportsPerhaps the most dynamic component of the Arctic sea ice cover is the marginal ice zone (MIZ), the transitional region between dense pack ice to the north and open ocean to the south.

Wave–sea-ice interactions in a brittle rheological framework [PDF]
The Cryosphere, 2021 As sea ice extent decreases in the Arctic, surface ocean waves have more time and space to develop and grow, exposing the marginal ice zone (MIZ) to more frequent and more energetic wave events.

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.

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 ...

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.

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.
