It means "having to do with the ocean or sea." The word "mar" is "sea" in several languages (such as Spanish, and it's "mer" in French), and is a derivation of Latin. So when someone mentions something "marine," like in "marine Biology," they're talking about something to do with water/in the sea - in marine bio, it's the study of plants (and sometimes animals) in the oceans. As for "Marines" such as in the Army, though, that's a different root, and I'm not sure of the original meaning.
