  1. The differences in shipping season lengths for Polar Class 6 (PC6) and Open Water (OW) ships were derived from the multi-model mean (MMM), Opt_SIC, and Opt_SIT experiments compared to the reference dataset (REF). The table presents the ratios of positive (\({R}_{{PD}}\)) and negative (\({R}_{{ND}}\)) differences.
