This datalayer consists of 25 distinct "statistical reporting areas" covering a large portion of the Gulf of Maine and south, including the territorial waters of the Commonwealth of Massachusetts. Fourteen of the areas compose the territorial waters, while the other 11 match those of the National Marine Fisheries Service areas for offshore bodies of water bordering the Commonwealth's territorial areas, including George's Bank. These areas are used mainly on maps for fishermen to report their landings (including lobster harvest), as well as for producing plots in various Massachusetts Division of Marine Fisheries (DMF) annual publications showing landings per area. The data distributed by MassGIS includes statistics for lobster harvest zones only; 1997 is the only year data currently available. In ArcSDE are two layers - LOBHARV_POLY and LOBHARV_ARC.
A polygon coverage was created from several different sources. State boundaries from Maine to Connecticut at 1:25,000 were combined to form a ‘New England' land coverage for basic reference and coastline. Existing territorial lines were combined as well as bathymetric and latitude-longitude lines to complete the polygons.
The polygon attribute table contains the following items:
AREA_ID - Statistical Area ID or Number
POUNDS97 - Lobsters Harvested in pounds for specific year
MassGIS is maintaining the datalayer. Updates will be made as yearly statistics become available from DMF.
