New method maps Arctic polynyas with high accuracy

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new framework for mapping Arctic polynyas using sea ice concentration data, employing hierarchical partitioning and region growing techniques. This method achieves high accuracy, with a mean overall accuracy of 96.74% and a kappa coefficient of 0.93 in visual assessments. Sensitivity analyses indicate that while the absolute extent of polynyas is highly dependent on chosen thresholds and data products, the broad temporal patterns and interannual structures remain relatively stable, suggesting that consistent monitoring requires explicit documentation of methodology.

    Mapping Arctic Polynyas from Sea Ice Concentration Data Using Hierarchical Partitioning and Differentiated Region Growing: Sensitivity to Threshold and Product Choices

    arXiv:2610.19647v1 Announce Type: new Abstract: Accurately delineating Arctic coastal polynyas from sea ice concentration data remains challenging because of complex coastal geometry and spatially heterogeneous ice conditions. We develop a daily sea ice concentration (SIC) mappin…
