Yeah, oceanology is a lot like a mix of biology and geology! I guess it really kind of covers most other branches of science, too (so it's probably a super hard class to take but I'd still like to try it out). But yeah I think it's so cool how much of the ocean is actually unexplored. o: As much as I love it it scares me a bit, too, especially thinking about how very deep it is and how there are lots of really weird creatures down there. Actually the ocean really just terrifies me altogether, but I still love it!
