Mid-Atlantic Coastal Acidification Network (MACAN)

Advancing Coastal Acidification Understanding and Adaptation Across the Mid-Atlantic

The Mid-Atlantic Coastal Acidification Network (MACAN) brings together scientists, federal and state agencies, tribal representatives, NGOs, educators, resource managers, and industry partners. Coordinated jointly by MARACOOS and the Mid-Atlantic Regional Council on the Ocean (MARCO), MACAN is one of seven regional networks in the U.S. dedicated to understanding and addressing ocean acidification.

MACAN’s Focus Areas:

• Enhance Understanding: Deepening knowledge of estuarine, coastal, and ocean acidification processes.
• Predict Consequences: Anticipating how ocean acidification affects marine ecosystems, resources, and communities.
• Enable Adaptation: Supporting industries and communities in preparing for and adapting to these changes.

Why It Matters in the Mid-Atlantic

The region is home to essential shellfish beds, migratory fish populations, and highly productive coastal ecosystems that underpin both commercial and recreational fisheries. Acidification, amplified by nutrient runoff from urban and developed areas, poses a threat to these resources. By providing critical data and guidance to scientists, resource managers, policymakers, and marine-based industries across the Mid-Atlantic, these insights help ensure sustainable fisheries, protect vital habitats, and support resilient coastal communities.
