Humboldt State University operates a marine laboratory on the rocky headland between the ocean and Trinidad Bay. Bay temperatures are taken from the fishing pier on the lee or southeast side of the headland. Ocean temperatures and salinity samples are taken from the beach on the northwest side, and returned to Scripps once a month for analysis. Except during periods of heavy runoff, salinity values from the coast and the bay are so similar that salinity samples are collected from the beach only.
