The Shore Stations Program collects and provides access to current and historical daily sea surface temperature (SST) and salinity (SSS) measurements observed at shoreline locations along the west coast of the United States. Currently, there are 10 active stations are located along the California coast, ranging from La Jolla to Trinidad. Data values are processed and published on the website by program staff at UCSD/Scripps Institution of Oceanography as they become available from each site. Program data are archived on a quarterly basis in the UCSD Library’s Digital Collections. https://doi.org/10.6075/J0S75GHD
