Courses and Faculty

All courses taught at the Station, the faculty and the years offered are given in Table I. Some courses have had high stability over time and some have been quite variable. It is important to have the same person teach a given course over a period of several years and thereby become thoroughly familiar with the region. There is also stimulus to be gained by having different people teach courses in alternate years.
