Scaling aspects of the sea-ice-drift dynamics and pack fracture [PDF]
Ocean Science, 2007 A study of the sea-ice dynamics in the periods of time prior to and during the cycles of basin-wide fragmentation of the ice cover in the Arctic Ocean is presented. The fractal geometry of the ice-sheets limited by leads and ridges was assessed using the

Frost flower chemical signature in winter snow on Vestfonna ice cap, Nordaustlandet, Svalbard [PDF]
The Cryosphere, 2009 The chemistry of snow and ice cores from Svalbard is influenced by variations in local sea ice margin and distance to open water. Snow pits sampled at two summits of Vestfonna ice cap (Nordaustlandet, Svalbard), exhibit spatially heterogeneous soluble ...

On the relationship between local stresses and strains in Arctic pack ice [PDF]
Annals of Glaciology, 1991 Local ice strains and in situ ice stresses were simultaneously measured on the Coordinated Eastern Arctic Experiment (CEAREX). The experiment took place in the fall of 1988 and was centered about an ice-strengthened ship moored to a multi-year floe in the pack ice northeast of Spitsbergen. During the period of data collection, which extended from early

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.

Winter Sightings of Marine Mammals in Arctic Pack Ice [PDF]
ARCTIC, 1987 There is limited information about the winter distribution of some arctic marine mammals. In February-March 1976 six species of marine mammals were sighted in the pack ice of Baffin Bay and Davis Strait. Hooded seals were sighted along the ice edge in February, but in late March adults with pups were seen.

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.

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.
