You're at UCSC? Is there both a PE class and a Science Class? Is the PE class taught by UC personnel, Aquasports, or other?
Yup, UCSC.
Office Of Physical Education, Recreation and Sports (OPERS) runs the recreational SCUBA program. There are two classes of OW per quarter, one AOW each quarter and two Rescue a year. They also offer DM and instructor once a year each. The instructors are UCSC employees (technically coaches, I think), and the OPERS locker has its own compressor and (guessing here) around 20 sets of gear and 40 tanks (AL80, AL63 and AL50s).

The scientific program is run by the Diving Safety Program, and the class is taught officially by the Biology department. The scientific diving class is taught twice a year and includes NAUI MSD and Nitrox in addition to sampling techniques and diving procedures. It comprised of six half-day pool sessions and 16 ocean dives, plus classroom. If you're interested, I'd love to talk about it more, but I suspect that you might already know most of it and that it might be of limited interest to the other viewers of the thread.
