Description: <div>PRELIMINARY &amp; EXPLORATORY LAYER – UNDER ACTIVE REVIEW</div><div><br /></div><div>This feature service provides a preliminary spatial representation of Block Area Closures (BACs) as defined in federal fisheries regulations (50 CFR 660.11). It was developed to support initial testing, visualization, and evaluation of potential BAC spatial boundaries.</div><div><br /></div><div>What are Block Area Closures (BACs)?</div><div><br /></div><div>Block Area Closures are designated areas in federal waters where trawl or non-trawl fishing may be prohibited to mitigate the bycatch of groundfish and protected species.</div><div><br /></div><div>BAC polygons are bounded:</div><div><br /></div><div><br /></div><div><br /></div><div>North and South: By a defined line of latitude or the Exclusive Economic Zone (EEZ) boundary.</div><div><br /></div><div>East and West: By regulatory boundary lines that approximate depth contours or the EEZ boundary.</div><div><br /></div><div><br /></div><div><br /></div><div>Current Status &amp; Scope</div><div><br /></div><div><br /></div><div><br /></div><div>Exploratory &amp; Non-Operational: This feature service is a working draft currently being evaluated for potential analytical and operational use.
