I will second (third?) the suggestion of Connecticut College. First, it is an excellent liberal arts college.
Second, as mentioned, they are very good with scholarship awards. I have a niece who is a student there and she is there because she got the best financial package there in addition to the the fact that it is an excellent college.
Third, as mentioned, Conn College has cross registration privileges with the Coast Guard Academy (one course per semester) which is literally right next door. So, majors at Conn College like Environmental Studies or Biological Sciences: Ecology Concentration can be supplemented with courses from the USCGA Marine & Environmental Sciences Dept, which is one of the majors at the Coast Guard Academy.
Fourth, for a student like your daughter with interests as diverse as Marine Biology, Classical Studies, and English, the Conn College curriculum is particularly appealing. Their approach is to not force you to choose among your interests but with the help of an advisor, to figure out how to weave them all together. They call it “Connections” and from the connections a student identifies among their diverse interests, they develop what Conn calls “Integrative Pathways”. Read about their approach on their website. It would seem to offer a lot to your daughter.
Fifth, Conn College is about 10 minutes away from Mystic Aquarium, one of the 5 largest aquaria in the United States. There are marine scientists on staff who are actively engaged in research and there are internships available to college students. The Mystic Aquarium staff are involved in projects and research ranging from marine animal rescue, to predator-prey studies, habitat mapping of Long Island Sound, deep sea coral studies on the continental shelf, and marine floor recovery studies. They are also involved in conservation policy development.
Sixth, the Conn College campus includes land - including a small island - on the Thames River estuary. New London Harbor is the best deep water port on Long Island Sound, which is why submarines are built there. So, there are opportunities right in a corner of campus to do coastal studies and observations.
Finally, as mentioned, Woods Hole Oceanographic Institute is about a 2 hour drive from campus. They offer summer internships with dormitory housing for college students. It doesn’t get any better than that if you want experiences in marine biology. Also, one of the “study away” options which Conn College offers is a semester-long immersion program in The Marine Biology Lab at Woods Hole. You can read about it on the college website.
