Don’t miss the chance to connect, share insights, and help shape the vibrant Mid-Atlantic ocean we all rely on.
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.

What We Do
As a Regional Ocean Partnership, MARCO helps coordinate among governmental agencies and across jurisdictions to plan for and effectively manage ocean and coastal change.

How we do it
The ocean is a complex place, and so is its management. MARCO hosts work groups, collaborative committees, and the Mid-Atlantic Ocean Data Portal to improve understanding of emerging issues, plan for changes in ocean use, share information and data, and identify ongoing research and data needs.

Why It Matters
Regional ocean planning improves understanding of how ocean resources and places are being used, managed, and conserved, and establishes a common foundation to guide actions that address shared management priorities.
