Spatial distribution of demersal and pelagic fishes in the wider Weddell Sea (Antarctica) with links to ArcGIS map packages
Here we provide four ArcGIS map packages with georeferenced files on the spatial distribution of demersal and pelagic fishes in the wider Weddell Sea (Antarctica), which were created in the context of the development of a marine protected area (MPA) in the Weddell Sea. Antarctic toothfish: The map o...
