Summary of Stranded Southern Sea Otters, 1985-2018 (ver. 3.0, June 2021) The southern sea otter (Enhydra lutris nereis), also known as California sea otter, was listed as threatened in 1977 under the Endangered Species Act. Since 1985, stranded otters from throughout their California coastal range have been collected and analyzed to inform resource management on recovery and conservation of the species. This data set is a complete 34 year compilation. Future annual stranding recovery information will be published when available. Stranded sea otters were collected by members of the sea otter stranding network (USGS, California Department of Fish and Wildlife (CDFW), Monterey Bay Aquarium (MBA), and the Marine Mammal Center (TMMC)) during routine beach walks and (more often) following...

Environmental samples were collected at selected sites to assess the effects of lead-based paint on soil chemistry. This sampling was made as part of a broader study to attribute sources of lead in soils in cooperation with the California Department of Toxic Substances Control (DTSC) for their Lead-Acid Battery Recycling Facility Investigation and Cleanup (LABRIC) program. Results of soil sampling and chemical analyses are included in the data-release component entitled "Soils chemistry from selected sites in Lakeport, Lake County, California"...
