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 ...

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 ...

Sensitivity of Arctic warming to sea ice concentration [PDF]
Journal of Geophysical Research: Atmospheres, 2016 AbstractWe examine the sensitivity of Arctic amplification (AA) to background sea ice concentration (SIC) under greenhouse warming by analyzing the data sets of the historical and Representative Concentration Pathway 8.5 runs of the Coupled Model Intercomparison Project Phase 5.

Artificial Neural Network for the Short-Term Prediction of Arctic Sea Ice Concentration
Remote Sensing, 2019 In this paper, we applied an artificial neural network (ANN) to the short-term prediction of the Arctic sea ice concentration (SIC). The prediction was performed using encoding and decoding processes, in which a gated recurrent unit encodes sequential ...

On the assimilation of ice velocity and concentration data into large-scale sea ice models [PDF]
, 2007 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.

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 ...

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.
