Suitability of the CICE sea ice model for seasonal prediction and positive impact of CryoSat-2 ice thickness initialization [PDF]
The CryosphereThe Los Alamos Community Ice CodE (CICE) sea ice model is being tested in standalone mode to identify biases that limit its suitability for seasonal prediction, where it is driven by atmospheric forcings from the NCEP Climate Forecast System Reanalysis ...

Sea-ice thickness measurement based on the dispersion of ice swell
The Journal of the Acoustical Society of America, 2012 The dispersion of flexural waves propagating in the Arctic sea ice cover is exploited in order to locally measure the ice thickness. The observed dispersion, for waves filtered in the 4–20 s period interval, at up to 4 broad-band seismometers deployed in Spring 2007 near the North Pole, is compared to a parameterized model that accounts for a complex ...

Sea ice in the Baltic Sea during 1993/94–2020/21 ice seasons from satellite observations and model reanalysis [PDF]
The CryosphereThis study investigates the sea ice characteristics of the Baltic Sea using Copernicus satellite and model reanalysis data products from 1993 onward. Our primary focus is on assessing the performance of the latest Copernicus model reanalysis product in ...

Arctic sea ice thickness and volume declining [PDF]
Eos, Transactions American Geophysical Union, 2013 The record low extent of Arctic sea ice area in September 2012 made headlines. Studies using models have suggested that sea volume has also been declining. A new study by Laxon et al. confirms this with observational data. The authors used satellite radar observations from the European Space Agency CryoSat‐2 mission to estimate Arctic sea ice thickness

Antarctic sea ice thickness affects algae populations [PDF]
Eos, Transactions American Geophysical Union, 2013 In the waters off Antarctica, algae grow and live in the sea ice that surrounds the southern continent—a floating habitat sure to change as the planet warms. As with most aquatic ecosystems, microscopic algae form the base of the Southern Ocean food web. Distinct algae populations reside in the sea ice surface layers, on the ice's underside, and within

A suite of coupled ocean-sea ice simulations examining the effect of regime shift in sea-ice thickness distribution on ice–ocean interaction in the Arctic Ocean [PDF]
Geoscientific Model DevelopmentA major shift in Arctic sea ice occurred in 2007, transitioning from thicker, deformed ice to thinner, more uniform ice with reduced surface roughness. This abrupt change likely altered the dynamic and thermodynamic interactions between sea ice and ocean,

Measuring sea ice through thick and thin [PDF]
Science, 2014 Climate Change Sea ice in the Arctic's Fram Straight is only half as thick as it was a decade ago, Renner and colleagues report. Measuring ice both at the surface and from the air with an instrument towed below a helicopter, they found that the ice in that region thinned by more than 50% between 2003 and 2012.

Frontiers in Marine ScienceThe accelerated decline of Arctic sea ice is profoundly reshaping regional climate regimes. Sea ice thickness (SIT), particularly under thin-ice conditions, is an important indicator for assessing early-season Arctic sea ice variability, and accurate ...

Recent Thickening of the Barents Sea Ice Cover
Geophysical Research LettersThe Arctic sea ice cover has decreased rapidly over the last few decades both in extent and thickness. Here we present multi‐year (2013–2022) observations of sea ice thickness in the northwestern Barents Sea based on Upward Looking Sonar measurements and
