Data Acquired

Survey EquipmentSurvey InfoData Type(s)Data Collected
Garmin --- Navigation
Ponar grab sampler --- Biology
Van Veen --- Biology
Moorings - Tripods --- Mooring (physical oceanography)
Water pressure/depth, velocity, and turbidity time-series data from SPB14 Bay shallows stations in San Pablo Bay and China Camp Marsh, California (Files contain hydrodynamic and sediment transport data for the location and deployment indicated. Time-series data of water depth, velocity, turbidity, and temperature were collected in San Pablo Bay and China Camp Marsh as part of the San Francisco Bay Marsh Sediment Experiments. Several instruments were deployed in tidal creek, marsh, mudflat, and Bay locations, gathering data on water depth, velocity, salinity/temperature, and turbidity. Deployment data are grouped by region (Bay channel (main Bay), Bay shallows, tidal creek, or marsh/mudflat/upper tidal creek). Users are advised check metadata and instrument information carefully for applicable time periods of specific data, as individual instrument deployment times vary.)
