Improving Multiyear Sea Ice Concentration Estimates with Sea Ice Drift [PDF]

open access: yesRemote 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).

The Identification of Ice Floes and Calculation of Sea Ice Concentration Based on a Deep Learning Method

open access: yesRemote Sensing, 2023
When navigating ships in cold regions, sea ice concentration plays a crucial role in determining a ship’s navigability. However, automatically extracting the sea ice concentration and floe size distribution remains challenging, due to the difficulty in ...

Accounting for Label Errors When Training a Convolutional Neural Network to Estimate Sea Ice Concentration Using Operational Ice Charts

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
Convolutional neural networks (CNNs) are being increasingly investigated as a means to extract sea ice concentration from synthetic aperture radar (SAR) in an automated manner. This is often done using ice charts as training data.

Sea and Freshwater Ice Concentration from VIIRS on Suomi NPP and the Future JPSS Satellites

open access: yesRemote Sensing, 2016
Information on ice is important for shipping, weather forecasting, and climate monitoring. Historically, ice cover has been detected and ice concentration has been measured using relatively low-resolution space-based passive microwave data.

Intercomparison of passive microwave sea ice concentration retrievals over the high‐concentration Arctic sea ice [PDF]

open access: yesJournal of Geophysical Research, 2007
Measurements of sea ice concentration from the Special Sensor Microwave Imager (SSM/I) using seven different algorithms are compared to ship observations, sea ice divergence estimates from the Radarsat Geophysical Processor System, and ice and water surface type classification of 59 wide‐swath synthetic aperture radar (SAR) scenes.

Sea Ice Concentration Estimation: Using Passive Microwave and SAR Data With a U-Net and Curriculum Learning

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Ice concentration estimates are typically acquired from algorithms using passive microwave satellite data, and from image analysis charts, but these have limitations. Estimates acquired from passive microwave data have coarse spatial resolution, may have

Analysis of Sea Ice Timing and Navigability along the Arctic Northeast Passage from 2000 to 2019

open access: yesJournal of Marine Science and Engineering, 2021
The ablation of Arctic sea ice makes seasonal navigation possible in the Arctic region, which accounted for the apparent influence of sea ice concentration in the navigation of the Arctic route.

Stochastic modeling of sea ice concentration fields for assessment of navigation conditions along the Northern Sea Route

open access: yesЛëд и снег, 2022
Article describes a probabilistic model (stochastic generator) of spatial-temporal variability of sea ice concentration. Values of the ice concentration are generated at the nodes of the spatial grid with 10 km resolution; the model time step is one day.
