Monitoring & Assessment

Salton Sea OFR The Salton Sea (Sea) is an ecosystem facing large systemic changes in the near future. Managers and stakeholders are seeking solutions to the decline of the Sea and have turned to the scientific community for answers. In response, scientists gathered in Irvine, California, to review existing science and propose scientific studies and monitoring needs required for understanding how to retain the Sea as a functional ecosystem. This document summarizes the proceedings of this gathering of approximately 50 scientists at a September 8–10, 2014, workshop on the State of the Salton Sea.

Connecting Habitats - Tracking birds with satellites and GPS

Oregon State University created a site that displays the long-range movements of Caspian terns in the Pacific Flyway.  By zooming in on the map, the data display this species marked birds use of the Salton Sea, and then by zooming out, their flight path is displayed along the entire Pacific Flyway.

Utah Department of Wildlife Resources created a site that tracks the long range movements of American White Pelicans from their breeding colonies to other wetlands, In particular several of their marked birds show up at the Salton Sea.

Water monitoring sources

The US Bureau of Reclamation initiated quarterly monitoring of the Salton Sea to provide information on changes in water quality occurring as a result of water conservation measures and other projects intended to improve or maintain water quality. Monitoring includes profiles for temperature, dissolved oxygen, pH, conductivity, and oxidation-reduction potential; major ion concentrations; nutrients; chlorophyll a; Secchi depth; and total and dissolved organic carbon.  The sampling sites illustrated in this map have been monitored quarterly on a continuing basis since 1999.
