Data sets

Daily MODIS composites of thin-ice thickness and ice-surface temperatures for the Southern Weddell Sea Paul, Stephan; Willmes, Sascha; Heinemann, Günther https://doi.org/10.1594/PANGAEA.848612

Short summary

We established a 13-year-long MODIS-derived thin-ice thickness data set from which we derived information about polynya dynamics in the southern Weddell Sea. In contrast to other studies, we do not focus on a single region but instead discuss polynya dynamics for the complete coastal area. The higher spatial resolution of MODIS compared to passive-microwave sensors enables us to resolve even very narrow coastal polynyas that would remain otherwise undetected.
