valid
This page provides information about the valid indicative distribution map for the ecosystem functional group M4.2 Marine aquafarms. For older or alternative maps, see here.
Methods
Here is the methods summary for Map code and version: M4.2.web.orig v1.0.
Marine ecoregions (Spalding et al. 2008) containing marine aquafarms were identified by consulting global and regional reviews, suitability maps (Gentry et al. 2017) and expertise of authors, proofed by specialist reviewers. These were clipped to the extent of the marine ‘shelf’ base layer as mapped by Harris et al. (2014b) and converted to 30 arc second spatial resolution. Occurrences were aggregated to half degree spatial resolution.
Datasets
