Underwater Environment

This course is to expose the diver to the physical and biological aspects of the diving environment with emphasis on the local area. This course will draw much of the subject material from related sciences, e.g., oceanography, limnology, geology, biology and ecology. The use of movies, slides and handouts are an important part of this course. Trips to aquariums and oceanariums will be most helpful. Effort, will be made to expose the student divers to several diving environments, e.g., lake vs. ocean, rocky reef vs. sand beach. (May be for skin or scuba divers.)

Subjects covered are as follows:

Plant and animal life - identification, relationships, dangers, regulations, uses - food collections and aquaria. Conservation and pollution - problem areas and possible solutions. Water movement and characteristics - tides, currents, waves and surf, temperature, pressure, density, buoyancy, visibility and sound. Shore, bottom and surface conditions - features, hazards, natural aids to navigation and wind effects. Diving locations - sources of information, use of charts, arranging and planning of dives.
