| Summary: | Leads and fractures in sea ice play a crucial role in the heat and gas exchange between the ocean and the atmosphere, impacting atmospheric, ecological, and oceanic processes. The precise knowledge of the aerial coverage, location, and formation history of leads is thus of great importance for polar research. Leads result from sea ice deformation processes. The breaking of the sea ice, followed by divergent ice motion, forms leads. Since the magnitude of divergence is directly proportional to the lead width, divergence is a powerful indicator of the location and width of leads. Divergence derived from satellite synthetic-aperture radar (SAR) data provides this information independent of the presence of clouds. We present here lead fractions from daily divergence fields in the Transpolar Drift along the drift of the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition in 2019/2020. The lead fractions have a spatial resolution of 700 m and are based on divergence from ... |
