Under-ice fauna abundance of Arctic pack ice north of Svalbard during the Polarstern expedition PS92 in 2015 [PDF]
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. Less sea ice is reaching the Fram Strait and more ice and ice-transported material is released in the

Winter sea ice export from the Laptev Sea preconditions the local summer sea ice cover and fast ice decay [PDF]
The Cryosphere, 2017 Ice retreat in the eastern Eurasian Arctic is a consequence of atmospheric and oceanic processes and regional feedback mechanisms acting on the ice cover, both in winter and summer.

Single-particle characterization of the high-Arctic summertime aerosol [PDF]
Atmospheric Chemistry and Physics, 2014 Single-particle mass-spectrometric measurements were carried out in the high Arctic north of 80° during summer 2008. The campaign took place onboard the icebreaker Oden and was part of the Arctic Summer Cloud Ocean Study (ASCOS).

A Submarine Sonar Study of Arctic Pack Ice [PDF]
Journal of Glaciology, 1975 AbstractA continuous profile of the Arctic Ocean ice canopy from Spitsbergen to the North Pole was made with 48 kHz echo sounders mourned on a nuclear submarine. A semi-automatic digitizer was used to measure coordinates from the records at a frequency of about 1 000 points per linear kilometre of track.

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 ...

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

Platelet Ice under Arctic Pack Ice in Winter [PDF]
Geophysical Research Letters, 2020 AbstractThe formation of platelet ice is well known to occur under Antarctic sea ice, where subice platelet layers form from supercooled ice shelf water. In the Arctic, however, platelet ice formation has not been extensively observed, and its formation and morphology currently remain enigmatic.

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
