This code estimates the proportional coverage of biotic and abiotic benthic habitats in Atlantis GOA, to be used for the biological parameterization. The code performs two tasks:
- It translates from maps of presence/absence or abundance of corals, sponges, and pennatulaceans in the Gulf of Alaska (Rooper et al. 2017), Aleutian Islands (Rooper et al. 2014), and British Columbia (Chu et al. 2019) to biotic habitat per box.
- It maps sediment data shared by Bob McCounnaghey (NOAA) and part of the dbSEABED database project to the Atlantis geometry.
See code for details.
