Our Mission: Improving the quality of life for the people of downeast and coastal Maine through marine research, marine science education, and innovations in wild and cultured fisheries.

Soft-shell clam research at Downeast Institute


DEI’s pristine, cold-water conditions, unique oceanographic features and state-of-the-art facility attract marine research scientists from around the world. DEI’s discoveries have advanced shellfish hatchery technology, increased knowledge of the marine environment and will continue to provide credible scientific information to policymakers, harvesters, and communities.



DEI ignites students’ enthusiasm for science by conducting hands-on lessons about the marine environment in our Education Center and in the field.  We provide exceptional experiential education for K-12 students, professional development for teachers,  and research opportunities for college students and faculty through our role as the University of Maine at Machias Marine Science Field Station.
