NOAA National Centers for Environmental Information. Dataset. California sea lions (Zalophus californianus) and Pacific harbor seals (Phoca vitulina) use offshore oil and gas platforms as resting and foraging areas. Both species are protected by the Marine Mammal Protection Act (1972). The Bureau of Ocean Energy Management (BOEM) is required to collect information from platforms being used by California sea lions and harbor seals (or other pinniped species) with the goal of meeting environmental review and permitting requirements associated with the eventual decommissioning of offshore platforms. Decommissioning requirements are under the jurisdiction of BOEMs sister agency, the Bureau of Safety and Environmental Enforcement (BSEE). However, BOEM provides environmental studies and environmental review support for BSEE actions. To accomplish this goal, BOEM entered an inter-agency agreement with the National Marine Mammal Laboratories' California Current Ecosystem Program (CCEP; AFSC/NOAA) in 2012. Specifically, BOEM funded CCEP to conduct a study (from January 2012 to January 2015) to characterize and quantify California sea lion and Pacific harbor seal use of the platforms, including; abundance, seasonal use patterns, and age and sex class composition of animals on the platforms. Inter- (i.e. spatial) and intra- (i.e. temporal) platform comparisons were examined. Quantify the abundance of California sea lions and Pacific harbor seals using oil and gas platforms and to assess their age/sex class and seasonal use patterns at each platform during a two-year (January 2013 - January 2015) period. Obtain information for the preparation of Marine Mammal Protection Act permit applications and National Environmental Policy Act environmental impact assessments for ongoing platform activities and the eventual decommissioning of platforms.

After consistency was established, images were analyzed. Questionable identifications were examined by at least two identifiers. Identifiers were conservative in their identifications (i.e. "Unknown" was used for individuals that it was difficult to determine their age/sex class). Completeness Report A subset of images based on a subset of time/day of a subset of days/month was analyzed for the study. Conceptual Consistency After animals were counted and identified to sex/age class, the images were reanalyzed to make sure all individuals were accounted for. Five of 23 oil and gas platforms in federal waters offshore San Pedro Bay, the Santa Barbara Channel, and in the Santa Maria Basin in the southern California Bight were selected as focal sites based on their geographical location and accessibility to animals. Time-lapse camera systems were deployed on those five platforms from January 2013 to January 2015. Photos were taken every 30 minutes over a 24-hour period. Images were uploaded from memory cards in the camera systems to a computer every 2-3 months. A subsample of images was randomly selected from six-hour blocks of time throughout the day, and during randomly selected days throughout each month. Individual pinnipeds were counted, and age- and sex-class were identified, when possible. Identifications and counts were used to characterize and quantify pinniped usage on the platforms. otherRestrictions otherRestrictions Access Constraints: None. | Use Constraints: Metadata are subject to revision at any time and information within the metadata record should not be cited without author consent.
