<p>Juaniata would be an obvious safety for you
Bates seems like a good bet, especially if you have done something relevant with your “gap”. We used to go to Reid and Popham State parks frequently, and many of the bio dept had aquatic interests.
I don’t think Midd is for you if you want marine bio. They do have an aquatic biologist, I think she does more like marine ecology.
College of the Atlantic really might be a great match for you.</p>
