Research Focus Areas

Initial broad research focus areas for GLMRI were mandated by Congress. These general focus areas have been refined with input from the Maritime Administration and various stakeholders. Each year at the GLMRI annual meetings, the Advisory Board determines future areas of research that build upon completed studies and take into consideration current issues and opportunities for research within the Great Lakes maritime community.
