Personnel of the City of San Clemente Department of Marine Safety take daily temperature and salinity samples from the San Clemente pier. Salinity samples are returned to Scripps monthly for analysis by salinometer.
Prior to 1970, sampling for this area was conducted at Dana Point (1955-1970). Because the conditions are so similar, the long record for this area has been maintained.
