Developing a Regional Perspective

The Mid-Atlantic Coastal Acidification Network (MACAN) is a nexus of scientists, tribal, federal, and state agency representatives, resource managers, and affected industry partners who seek to coordinate and guide regional observing, research, and modeling of ocean and coastal acidification. MACAN works to develop a better understanding of the processes associated with estuarine, coastal, and ocean acidification, predict the consequences for marine resources, and devise local adaptation strategies that enable communities and industries to better prepare and adapt. MACAN also helps to fulfill the needs of other regional entities where objectives align.


MACAN serves as an information hub and exchange among research, industry, and resource managers focusing on waters and impacted species from south of Long Island to and including Virginia. Network members work collaboratively on identifying and pursuing opportunities to address coastal and ocean acidification in the Mid-Atlantic, building upon the skills and interests of individual members and providing a forum to share best practices in monitoring and sampling collection.

Why Are We Working on This?

The Mid-Atlantic is home to shellfish and migratory fish habitats that support economically valuable commercial and recreational fisheries that may be impacted by ocean acidification. The Mid-Atlantic is also densely populated and urbanized, and its developed coastal counties drain nutrients and other materials through the region’s rivers, into several major estuarine systems causing coastal and estuarine processing that exacerbate ocean acidification. Acidification has scientific and societal ramifications including the alteration of ocean biogeochemistry, ecological consequences associated with altered ecosystems, and economic losses due to the decrease of commercially important organisms. 


MACAN is one of many regional acidification networks across the United States. MACAN is coordinated by the Mid-Atlantic Regional Association Coastal Ocean Observing System (MARACOOS) and the Mid-Atlantic Regional Council on the Ocean (MARCO).
