The Mid-Atlantic Regional Council on the Ocean is committed to improving and increasing engagement with State and Federally recognized Tribes in the Mid-Atlantic Region as well as those with ancestral ties to the Mid-Atlantic. Incorporating and preserving tribal knowledge within ocean conservation efforts not only deepens our understanding but also strengthens the effectiveness and long-term sustainability of conservation strategies.


MARCO is looking to ensure Tribal members are able to attend as well as present at any meeting in which their Tribe has a vested interest. Please email with the subject, “Tribal Member Travel Support Request” if you would like to participate in any of MARCO’s upcoming meetings and require travel support. 


Upcoming Meetings:

NOAA’s Ocean Acidification Program (OAP) Education Mini-Grant Program, is a competitively-based initiative that supports coastal and ocean acidification education programs that are responsive to the goals of the NOAA Ocean Acidification Education Implementation Plan and the 2021-2040 NOAA Education Strategic Plan. Priority goals include engaging diverse audiences in ocean acidification education and outreach, matching ocean acidification communication needs with existing research, education and outreach activities, while developing innovative approaches for community involvement. These goals are part of NOAA’s efforts to increase Diversity, Equity, Inclusion, and Accessibility (DEIA) ( in ocean literacy, stewardship, and workforce development, particularly in underserved and/or Indigenous communities or Tribes.
