The Mid-Atlantic’s Regional Ocean Partnership

The Mid-Atlantic Regional Council on the Ocean (MARCO) was established by the governors of Virginia, Maryland, Delaware, New Jersey, and New York to address shared regional priorities and provide a collective voice for a healthy ocean ecosystem and economy. It is one of four Congressionally-authorized Regional Ocean Partnerships (ROPs) in the United States.

Why a regional approach is important

The coastal region between Virginia and New York is some of the most heavily trafficked, touristed, and populated in the country. As the region’s population increases and ocean uses intensify, the Mid-Atlantic is faced with pressing ocean management challenges and opportunities. By working together, MARCO’s five States foster more effective federal and private investment in priority ocean and coastal issues for the States.
