A. There are many schools that offer such courses. The North American Benthological Society recently published a list of these together with instructors' names. I would be glad to xerox and send you the entire list if you want it, or if you are looking for a school in a certain vicinity (state?), I could just extract that information and send you that list via mail or e-mail. If you want the list mailed, be sure to send me a mailing address. Let me know at cecushing@aol.com.
