To expand geologic mapping to the seafloor within the California's State Waters, to update coastal geologic mapping, and to contribute to a uniform regional geologic database. Additionally, to provide a geologic map for the public and geoscience community to aid in assessments and mitigation of geologic hazards in the Monterey Bay and Vicinity region and to provide sufficient geologic information for land-use and land-management decisions both onshore and offshore.
