Machine Learning-Based Image Processing for Ice Concentration during Chukchi and Beaufort Sea Trials
Journal of Marine Science and Engineering, 2023 Growing interest in finding the optimal route through the arctic ocean, and sea ice concentration is also emerging as a factor to be considered. In this paper, an algorithm to calculate the sea ice concentration was developed based on the images taken ...

Assimilation of sea-ice concentration in a global climate model — physical and statistical aspects [PDF]
, 2012 We investigate the initialisation of Northern Hemisphere sea ice in the global climate model ECHAM5/MPI-OM by assimilating sea-ice concentration data. The analysis updates for concentration are given by Newtonian relaxation, and we discuss different ways

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 Sea ice concentration algorithms using brightness temperatures ($T_{B}$) from satellite microwave radiometers are used to compute sea ice concentration ($c_{\text{ice}}$), sea ice extent, and generate sea ice climate data records. Therefore, it is important to minimize the sensitivity of $c_{\text{ice}}$ estimates to geophysical noise caused by snow ...

Arctic Sea Ice Concentration Assimilation in an Operational Global 1/10° Ocean Forecast System
Remote Sensing, 2023 To understand the Arctic environment, which is closely related to sea ice and to reduce potential risks, reliable sea ice forecasts are indispensable. A practical, lightweight yet effective assimilation scheme of sea ice concentration based on Optimal ...

The Arctic sea ice cover of 2016: a year of record-low highs and higher-than-expected lows [PDF]
The Cryosphere, 2018 The Arctic sea ice cover of 2016 was highly noteworthy, as it featured record low monthly sea ice extents at the start of the year but a summer (September) extent that was higher than expected by most seasonal forecasts.

Erroneous sea-ice concentration retrieval in the East Antarctic [PDF]
Annals of Glaciology, 2018 ABSTRACTLarge discrepancies have been observed between satellite-derived sea-ice concentrations(IC) from passive microwave remote sensing and those derived from optical images at several locations in the East Antarctic, between February and April 2014. These artefacts, that resemble polynyas in the IC maps, appear in areas where optical satellite data ...
