I know a lot of you guys are SCUBA divers, and maybe also interested in Marine Science. If that's the case then I highly recommend you guys sign up for the Scientific Dive Course here at UCSB. Its an amazing, intensive course, that I'm currently taking, that will train you to become scientific diving certified. With that you can do research dives for many of the marine labs on campus. Many labs go out frequently to do anything from catching fish for classes to just completing surveys of local ecosystems. This course will allow you to help out, and in some cases even get paid to dive, with many labs. The course is offered twice a year, the month before fall quarter starts and during spring break.

And for those of you interested, but not SCUBA certified, the UCSB Rec Cen also offers a SCUBA class every quarter, not a credit course, that is really great. I got my cert through UCSB and the class was amazing and one of the cheapest options out there for students.
