CABRILLO Southern California Regional Synthesis

A deeper understanding of the interrelationships between oceans, coastal aquifers, tectonics, human populations, and natural forces provides for successful management of southern California's resources and hazards. The Regional Synthesis task in an integrated scientific study of physical processes, water chemistry, sediment transport, coastal aquifers, earthquakes, and biohabitats. This type of study is required in the understanding of how natural and anthropogenic changes have affected coastal ecosystems in the past, and how these changes continue to affect our resources.

With new multibeam technology, scientists are able to 'drain the water' from the ocean using digital technology. The image above shows the shelf and slope deposits of the Santa Monica and San Pedro Bays offshore Los Angeles.  The flat, tan areas are the shelf deposits (shelf break ~100 meters), grading into the yellow-to-green slope deposits (400-600 meters) and finally the blue basins (600-800 meters).

The regional synthesis offshore study area for Southern California extends from just north of Pt. Arguello to the Mexican border, and from the coast to the 200-mile limit of the EEZ (Exclusive Economic Zone) (See boundary and selected study areas on the above map.)
