Leads and pressure ridges are dominant features of the Arctic sea ice cover. Not only do they affect heat loss and surface drag, but also provide insight into the underlying physics of sea ice deformation. Due to their elongated shape they are referred as Linear Kinematic Features (LKFs). This data-set includes LKFs that were detected and tracked in sea ice deformation data obtained during the MOSAiC expedition from Sentinel-1 SAR data (von Albedyl & Hutter, 2023). The data-set spans the winter months between October 2019 and May 2020. A detailed description of the data-set and of the algorithms deriving it is provided in Hutter et al. (2019). We used the updated version of the algorithm for the data processing (Hutter, 2023). The dataset is closer described in Ringeisen et al. (2023).
