Offshore Habitat Zone polygons

Source: R/data.R

Offshore habitat zones used for summary statistics and derived from BOEM 2019-2024 Draft Proposed Program Areas for the lower 48 (excluding Hawaii and Alaska), clipped by the United States Exclusive Economic Zone (EEZ). A second version was further intersected with the OceanAdapt Regions for bottom trawl models, since the available data is markedly different inside versus outside these model results.
