bladephotog:Maritime Archaeological Survey Team holds courses each year in nautical archaeology. I've heard it's a great course.
From their website - "MAST, the Maritime Archaeological Survey Team is a nonprofit avocational group dedicated to the documentation of Ohio's underwater historic resources. Formed in March of 2000, MAST is composed of volunteer individuals who support and participate in research, documentation, underwater archaeological surveys, and educational workshops."
