Description:

There are 23 oil and gas production platforms in federal waters offshore southern California. These platforms provide haul-out space near foraging areas for California sea lions (Zalophus californianus), a species protected under the Marine Mammal Protection Act. Information on abundance and age-, sex-, and seasonal-use patterns of California sea lions on oil and gas platforms is useful for the environmental review of ongoing activities and the eventual removal of platforms when oil and gas production ceases. Quantitative estimates of potential harassment, injury, or mortality for future activities may be derived from data collected during this study.
