Temperature, Salinity (Beach only)
Measurements are made at the Humboldt State University Marine Laboratory, located on the rocky headland between the Pacific Ocean and Trinidad Bay. Bay temperature is measured from the fishing pier on the lee or southeast side of the headland. Ocean temperature and salinity samples are taken from the beach on the northwest side. Salinity samples are returned to Scripps once a month for analysis. Except during periods of heavy runoff, salinity values from the coast and the bay are nearly identical.
