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 ...

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

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.

The effect of sea-ice parameterizations on the simulation of the Arctic ice pack [PDF]
Annals of Glaciology, 1997 A one-dimensional (1-D), thermodynamic sea-ice model with parameterized ice dynamics is coupled to a mixed-layer ocean model and driven with prescribed atmospheric forcings for the central Arctic.

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.

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.

Status and trends in the structure of Arctic benthic food webs [PDF]
Polar Research, 2015 Ongoing climate warming is causing a dramatic loss of sea ice in the Arctic Ocean, and it is projected that the Arctic Ocean will become seasonally ice-free by 2040.

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.

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.
