MARCO and MACO collaborate with governmental agencies, tribal nations and many other interested stakeholders through a series of specially focused work groups. Their areas of concentration are:

Marine Debris: Reduction and prevention of litter such as balloons that pose a hazard to marine life

Healthy Ocean Indicators: The development of indicators to measure ocean health

Non-Consumptive Recreation: Increased consideration of the importance of non-consumptive recreation

Ocean Acidification: The continued development of a comprehensive ocean acidification monitoring network and research plan through the Mid-Atlantic Coastal Acidification Network

Ocean Mapping and Data: Continued operations, maintenance and updating of the Mid-Atlantic Ocean Data Portal, including convening the MARCO Ocean Mapping & Data Team. The Portal Work Plan can be downloaded here.


Additional work groups or other coordination efforts will be established and led by MARCO, federal agencies or other regional ocean partners to address emerging priorities over time, based on available resources. Inquiries to any of these work groups may be directed to
