NOAA-Southwest Fisheries Science Center scientists are involved in leatherback conservation in various regions of the Pacific. Our research focuses on the genetic structure, demographics, abundance, habitat use, and migration of leatherbacks across the Pacific, with an emphasis on the western Pacific nesting population, which nest in Papua, Indonesia. We work with local organizations in Papua to coordinate nesting beach conservation programs and carry out satellite telemetry and aerial surveys to study the movements, habitat use, and abundance of leatherbacks in the South China Sea. In the Eastern Pacific, we conduct aerial surveys, capture at sea, and satellite telemetry of leatherback turtles off the west coast of the United States, in California, Oregon, and Washington. In the Southeast Pacific, we collaborate with non-governmental and governmental organizations in Ecuador, Peru, and Chile in efforts to characterize leatherback bycatch and improve bycatch reduction technologies.
