(2017), the RME masks were provided by the modelling groups already participating in ISIMIP.<br>Annual maps and gridded layers of global MPA coverage from 1958 to 2025 (Roberts, K. E., et al., in prep.), constructed from the ProtectedSeas Navigator database (Zetterlind et al., 2025). Includes both comprehensive MPA coverage (all) and a strict protection subset, delivered as zipped shapefiles, NetCDF, and GeoTIFF formats at 1\u00b0 and 0.25\u00b0 spatial resolutions.<br>Version 1.1 adds the MPA masks.",
