During my tenure at SDSU, I participated in numerous scientific diving expeditions to the California Channel Islands (Lang and Hochberg, 1997), Baja California, and a most stimulating trip to the Antarctic on an Euphausia superba research diving project with Bill Hamner from UCLA. Scientific diving in the United States can be traced to Scripps Institution of Oceanography in 1951. Conrad Limbaugh (Fig. 4a) was appointed by Roger Revelle as the first Diving Officer of the University of California's scientific diving program. This program provided for scuba training, equipment maintenance, medical and operational underwater research procedures—elements that are still found in diving programs today. Jim Stewart (Fig. 4b) succeeded Limbaugh in 1960 after his tragic death in a submarine cave diving accident in Port Miou, France at the age of 35. The Capricorn expedition to the South Pacific in 1954 was the first research diving cruise to study coral reefs. Those were the days of double-hose regulators and twin tanks. There were no buoyancy compensators, submersible pressure gages or dive 4^» computers. When it got hard to breathe, divers came up following their smallest bubbles, or sometimes completely disregarding the ascent rate based on the length of time they had been out of air! J-valves were incorporated on scuba cylinders in the 1960s as a safety mechanism in order to provide a reserve supply of air of approximately 300 psi. At issue was t
