Between 1995 and 2011, we surveyed the fish assemblages of 22 oil and gas platforms off southern California using the manned research submersibles Delta and Dual DeepWorker. This work was funded by the United States Bureau of Ocean Energy Management (previously the Minerals Management Service), the Biological Resources Division of the United States Geological Survey, and the California Artificial Reef Enhancement Program. The data from these surveys was entered into a Microsoft Access database—we call it Rigbase—and we present that database here.
