CeNCOOS in situ water quality monitoring using the seawater input for Moss Landing Marine Laboratory

The Seawater intake station is maintained by Moss Landing Marine Laboratories who share the data with CeNCOOS. Data collected includes temperature, conductivity, salinity, fluorescence, beam attenuation, transmission, dissolved oxygen, dissolved organic saturation, pH, and tide height. Seawater data observations are collected from raw seawater drawn through an intake pipe. The pipe intake opening is located at 36.8025N and 121.7915W and is ~16.6m (54.4ft) below MLLW. The seawater sensors are cleaned of biofouling agents on a weekly/twice-weekly interval, though some data drift can be observed in transmission, beam attenution, and fluorescence. These nearshore sensors are part of the Central and Norther California Ocean Observing System (CeNCOOS). They measure various water quality parameters at fixed points along the California coast.
