ARCTIC, 1979
This paper examines how sea ice floes of thickness exceeding 6 m can be formed in the Arctic. Such floes have been observed by a Soviet drifting station, by a submarine at the North Pole, and at three sites in the Canadian Arctic Archipelago. The Maykut and Untersteiner model of sea ice growth predicts an equilibrium thickness of 3 m under normal ...

Sea ice deformation and sea ice thickness change
2022The Arctic Ocean is undergoing a major transition from a year-round sea ice cover to ice-free summers with global consequences. Sea ice thickness is at the center of the ongoing changes because the thickness regulates key processes of the Arctic climate system and in the last six decades, the mean thickness has more than halved.

The thickness distribution of sea ice
Journal of Geophysical Research, 1975The polar oceans contain sea ice of many thicknesses ranging from open water to thick pressure ridges. Since many of the physical properties of the ice depend upon its thickness, it is natural to expect its large-scale geophysical properties to depend on the relative abundance of the various ice types.

Improved sea-ice prediction in the Weddell Sea using sea-ice thickness initialization
2021<p>Skillful sea-ice prediction in the Antarctic Ocean remains a big challenge due to paucity of sea-ice observations and insufficient representation of sea-ice processes in climate models. This study demonstrates that the Antarctic sea-ice concentration (SIC) prediction is significantly improved using a coupled general circulation model ...

Arctic sea ice thickness changes in terms of sea ice age
Acta Oceanologica Sinica, 2016In this study, changes in Arctic sea ice thickness for each ice age category were examined based on satellite observations and modelled results. Interannual changes obtained from Ice, Cloud, and Land Elevation Satellite (ICESat)-based results show a thickness reduction over perennial sea ice (ice that survives at least one melt season with an age of no

Walking on snow-covered Arctic sea ice to infer ice thickness
The Journal of the Acoustical Society of America, 2022The ice-covered Arctic Ocean constitutes a unique underwater acoustic waveguide; it is a half-channel, upward refracting environment possessing a rough upper boundary consisting of sea ice of varying thickness. The sea ice itself is an acoustic waveguide, capable of supporting the propagation of compressional and shear waves.

Sea Ice Thickness Forecast Performance in the Barents Sea
Volume 7: Polar and Arctic Sciences and Technology, 2020Abstract The presence of sea ice has a major impact on the safety, operability and efficiency of Arctic operations and navigation. While satellite-based sea ice charting is routinely used for tactical ice management, the marine sector does not yet make use of existing operational sea ice thickness forecasting.

Hydrographische Nachrichten, 2023
This work explores the potential of using commercial single-beam echo sounders for accurate thickness determination of sea ice. Therefore, an own sensor system has been developed which allows to study the performance of different echo sounders monitoring sea ice under varying environmental conditions in a laboratory setup. The sensor system consists of

The sea ice thickness distribution in the northwestern Weddell Sea
Journal of Geophysical Research: Oceans, 1991We present new data on distribution of snow and sea ice thicknesses in the northwestern Weddell Sea. The data were obtained through direct measurements along 19 profiles, each approximately 100 m long on 17 different floes located between 54°–46°W and 59°–64°S.

Improving sea-ice cover and SST forecasts by sea-ice thickness initialization
2020<p>A substantial amount of subseasonal-to-seasonal sea-ice variability is potentially predictable, but improved model biases and initialization techniques are needed to realize this potential. Forecasts for other Earth System components can be expected to benefit from improved sea-ice forecasts as well, because the presence of ...
