Deformation lines in Arctic sea ice: intersection angles distribution and mechanical properties - codes and intersection angle data

Code and data to reproduce the results presented in Ringeisen et al. (2023). The included notebooks compute intersection angle distributions and distributions of deformation rates along LKFs, as well as derive yield curves from intersection angle distributions. The intersection angle data sets have been extracted from three different LKF datasets:
