near real-time data from the heart of the Santa Monica Bay

The Santa Monica Bay Observatory mooring is located at 33° 56'N, 118°43'W inside Santa Monica Bay at a water depth of about 450 m. Data are telemetered back to UCLA daily via radio and made available to the public through our LAS server. Each day we also produce a series of standard plots. For photos and impressions, follow this link.

The current deployment began on March 6, 2006.

Currently, the mooring is instrumented as follows:

  • Basic meteorological parameters (air temperature, windspeed, wind direction)
  • Global Positioning System
  • Conductivity, temperature, pressure sensors down to 100 m water depth
  • Transmissometer and fluorometer at approximately 0.5 m water depth
  • Downward looking Acoustic Doppler Current Profiler (ADCP) at about 2 m water depth
  • Air-sea partial pressure of CO2 and oxygen difference analyzer (not continuous)

Follow this link for a more detailed description of the sensors.

The SMBO mooring is currently supported by grants from NSF and from NOAA. If you have questions/inquiries, please contact the Nicolas Gruber ( (Lead PI) or Levanto Schachter ( (Marine technician).
