Buzzards Bay Study Area

In 2009, the NEP “Study Area” definition (jurisdictional interests of the program) was revised to be consistent with the Massachusetts Ocean Plan area and coincident with the boundary of Massachusetts state waters, and within recently defined state and federal designations for the boundary of Buzzards Bay. In 2014, 2021, and 2024, the boundary was further refined as described on our NEP study area, especially in the northern boundary, and Cape Cod boundary further to reflect new watershed boundaries defined by the Massachusetts Estuaries Project and USGS models in those areas.
