Data

Model output data used for this analysis can be extracted from FishMIP, available at (https://www.isimip.org/about/marine-ecosystems-fisheries/). Outputs for ESMs can be found in the ISIMIP website (https://data.isimip.org/). Polygons for the Arctic Large Marine Ecoregions were extracted from Protection Of The Marine Environment-PAME (https://pame.is/projects/ecosystem-approach/arctic-large-marine-ecosystems-lme-s)
