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 ...

Sea ice thickness distribution in the Arctic Ocean
Cold Regions Science and Technology, 1987Abstract Data from the unclassified literature were reviewed to determine the regional and seasonal distributions of sea ice thickness, pressure ridging statistics, frequency of occurrence of polynyas, and keel/sail height ratios. Seasonal and regional maps and histograms of these properties were constructed.

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 and production in Weddell Sea polynyas
2022<p>Open-ocean and coastal polynyas, the result of high-latitude atmosphere-ocean circulation interannual variability, alter the local air-ocean heat exchange and sea ice production. Yet, the role of the ocean, especially its thermal flux, is rarely discussed.

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.

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
