Abstract
A subtidal study of the benthic flora and substrate relief was conducted within the kelp bed off Del Monte Beach, near Monterey Harbor, Monterey, California. The study was carried out by utilizing SCUBA equipment, aerial photography, and ocean wave
refraction/numerical computer programs.
During the course of the SCUBA investigation, approximately fifty species of benthic algae
were collected. The occurrences of the most abundant genera were mapped symbolically if they were observed within the boundaries of four pre-selected 12 meter square quadrat sites.
A preliminary analysis of the mapped data indicated that the frequency and density of five defined algal groups varied in relation to certain types of substrate. Aerial photographic
interpretations revealed yearly variations in the
kelp bed surface canopy. Theoretically derived refraction computations along a wave energy
gradient were consistent with some observed changes in kelp bed species distribution.
