Description

This survey is unusually comprehensive due to the wide geographic area, depth range, variety of habitats and intensive collecting throughout Southern California. Different teams sampled intertidal areas (rocky, sandy, and slough), subtidal (soft sediment and rock substrate), kelp beds, and mussel communities for biotic, chemical, and geologic data. Subtidal areas included mainland shelf and slope, nearshore basins, island shelves, intermediate basins and slopes, outer banks, and deep outer basins and slopes. Large numbers of specimens were collected, providing excellent documentation of community composition, life history, interspecific and intraspecific variability over space and time. In addition, many undescribed species were found during the study.
