Ice-tethered observational platforms in the Arctic Ocean pack ice
IFAC-PapersOnLine, 2016 Abstract: The Arctic Ocean faces rapid climate change, which impacts both physical and biological components of the marine ecosystem. Due to complicated and costly logistics inherent to sampling ice-covered areas, most studies conducted in the Arctic are based on relatively short-term sampling (weeks to months) centered around the minimum ice season.

A red tide in the pack ice of the Arctic Ocean [PDF]
Scientific Reports, 2019 AbstractIn the Arctic Ocean ice algae constitute a key ecosystem component and the ice algal spring bloom a critical event in the annual production cycle. The bulk of ice algal biomass is usually found in the bottom few cm of the sea ice and dominated by pennate diatoms attached to the ice matrix.

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

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.

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.

The seeding of ice algal blooms in Arctic pack ice: The multiyear ice seed repository hypothesis
Journal of Geophysical Research: Biogeosciences, 2017 During the Norwegian young sea ICE expedition (N-ICE2015) from January to June 2015 the pack ice in the Arctic Ocean north of Svalbard was studied during four drifts between 83° and 80° N. This pack ice consisted of a mix of second-year, first-year and young ice.
