Station Details

  • Station Description

    The Carquinez shore station is located on the Cal Maritime pier. The station has been operational since 2008 and consists of in-water sensors. The water quality sensors provide near-real time observations of water salinity, temperature, dissolved oxygen, chlorophyll fluorescence, turbidity and pH. This station is maintained by SF State/EOS Center and Cal Maritime and is part of the COMS project.

  • Location

    38.0657N, 122.2302W

  • Sensor Information

    YSI 6600v2

  • Available Parameters

    WATER QUALITY MEASUREMENTS

    Sensor Depth
    Distance the sensors are below the water's surface. The sensors are in a fixed position attached to a pier, so depth also measures tidal range. (units = meters or feet)
    Water Temperature
    Water temperature at sensor depth. (units = °C or °F)
    Salinity
    Salt content of the water at sensor depth. (units = Practical Salinity Scale 1978)
    Chlorophyll
    Phytoplankton pigment concentration at sensor depth estimated from fluorescence measurements. (units = µg chlorophyll L-1)
    Turbidity
    The clarity of the water at sensor depth. (units = nephelometric turbidity units, NTU)
    Dissolved O2
    The amount of oxygen dissolved in water. (units = mg L-1 or % of saturation)
    pH
    Acidity or alkalinity of the water at sensor depth. (units = -log[H+])
    Density
    The mass per unit volume of water. (kg m-3)

Water Quality Data Access

Water Quality data is available through our ERDDAP data server in a variety of formats including .csv, .xls, .mat and more.

There are two links to water quality data: the first link allows for quick access to provisional real-time data from the past few weeks. The second link provides the data archive for the current water quality station.

Conductivity, salinity, water temperature, turbidity, total dissolved solids, chlorophyll, pH, dissolved oxygen, and water depth data are available at a sampling frequency of 6 minutes.
