A Statistical Approach for Estimating Sea Ice Thickness
Volume 6: Polar and Arctic Sciences and Technology, 2023Abstract Sea ice reporting and ice charts are a necessary simplification of highly variable sea ice conditions over large areas. Ice conditions are typically shown using egg codes. These codes can be used to determine an equivalent ice thickness as a method for calculating a ship’s ice resistance.

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.

Estimating the thickness of sea ice
Journal of Geophysical Research: Oceans, 1989Sea ice freeboard, thickness, and snow depth were measured from a series of closely spaced (5 to 10 m) drill hole sites from five free‐floating multiyear ice floes in the Beaufort Sea during the spring of 1986 and 1987. A regression of ice thickness on ice draft was performed on the data from each floe and for the combined data set.

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.

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.

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

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.

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 ...

Sea-ice thickness and mass at Ice Station Belgica, Bellingshausen Sea, Antarctica
Deep Sea Research Part II: Topical Studies in Oceanography, 2011Abstract Ice Station Belgica was commenced in late winter 2007 in the Bellingshausen Sea as part of Sea Ice Mass Balance in Antarctica (SIMBA), an IPY 2007 cruise on the research vessel N.B. Palmer. A primary objective was to build on the work of previous Antarctic drift station experiments to geophysically characterize sea ice in terms of thickness,
