Improving Multiyear Sea Ice Concentration Estimates with Sea Ice Drift [PDF]
Remote Sensing, 2016 Multiyear ice (MYI) concentration can be retrieved from passive or active microwave remote sensing observations. One of the algorithms that combines both observations is the Environmental Canada Ice Concentration Extractor (ECICE).

Vertical ocean heat redistribution sustaining sea-ice concentration trends in the Ross Sea. [PDF]
Nat Commun, 2017 AbstractSeveral processes have been hypothesized to explain the slight overall expansion of Antarctic sea ice over the satellite observation era, including externally forced changes in local winds or in the Southern Ocean’s hydrological cycle, as well as internal climate variability.

Impact of assimilating sea ice concentration, sea ice thickness and snow depth in a coupled ocean–sea ice modelling system [PDF]
The Cryosphere, 2019 The accuracy of the initial state is very important for the quality of a forecast, and data assimilation is crucial for obtaining the best-possible initial state.

Sea ice concentration inversion based on different Arctic sea ice types
Frontiers in Marine ScienceThe ASI algorithm uses the same sea ice and seawater tie-points when inverting polar sea ice concentration (SIC), but this approach does not fully consider the differences between different polar sea regions and the impact of different sea ice ...

Impurity Concentrations In Sea Ice [PDF]
Journal of Glaciology, 1977 Abstract Three different types of saline ice were cut into sections a few millimeters thick along planes parallel to the surface. The resulting melts were analyzed quantitatively for chloride, sulphate, sodium, potassium, magnesium, and calcium. Two of the specimens were artificial sea ice, grown in the laboratory at ambient temperatures of

On the assimilation of ice velocity and concentration data into large-scale sea ice models [PDF]
Ocean Science, 2007 Abstract. Data assimilation into sea ice models designed for climate studies has started about 15 years ago. In most of the studies conducted so far, it is assumed that the improvement brought by the assimilation is straightforward. However, some studies suggest this might not be true.

On the measure of sea ice area from sea ice concentration data sets [PDF]
SPIE Proceedings, 2015 The measure of sea ice surface variability provides a fundamental information on the climatology of the Arctic region. Sea ice extension is conventionally measured by two parameters, i.e. Sea Ice Extent (SIE) and Sea Ice Area (SIA), both parameters being derived from Sea Ice Concentration (SIC) data sets.
