Scripps is located in the South Coast region of California, midway between the Scripps Institution of Oceanography Pier and Black's Canyon in La Jolla, in the Scripps UC Coastal Reserve. The site is located in an Area of Special Biological Significance (San Diego Marine Life Refuge ASBS), within the San Diego-Scripps Coastal State Marine Conservation Area, and is near the Scripps Reef Mussel Watch site. This site receives a high number of visitors, including tidepoolers, students, and scientists. Various class projects and research studies have been conducted here by UC San Diego and Scripps personnel, with authorization and documentation by the Scripps Coastal Reserve. This gently sloping site consists of moderately uneven terrain, containing many boulders and crevices.

Scripps biodiversity survey overview

Scripps is dominated by a mixture of consolidated sedimentary and metamorphic bedrock, boulder fields, and sandy beach, and the area surrounding the site is comprised of sandy beach with upper intertidal boulders and rock outcrops. Sand can fluctuate over one meter within a single year at this site and may play a dominant role in structuring the community. The primary coastal orientation of this site is west.

Long-Term Monitoring Surveys at Scripps were established in 1997, and were previously done by University of California Santa Barbara, but are currently done by Cabrillo National Monument. Long-Term MARINe surveys currently target the following species: Chthamalus/Balanus (Acorn Barnacles), Pollicipes (Goose Barnacle), Mytilus (California Mussel), Silvetia (Golden Rockweed), Red Algal Turf, Phyllospadix (Surfgrass), and Pisaster (Ochre Star).

Scripps long-term monitoring overview

Biodiversity Surveys were done by University of California Santa Cruz in 2002, 2006 and 2010. The Biodiversity Survey grid encompasses one section that is approximately 29.6 meters (along shore) x 40 meters (seaward). Click here to view Biodiversity Survey findings at this site.
