Field Activity ID111SF

Identifier ID111SF
Alternate names I-D1-11-SF
Purpose To determine the mechanisms driving the exchange of sediment between subitdal and intertidal habitats, and to determine how resuspension from the bed is affected by wetting and drying.
Description United States Geological Survey, Pacific Science Center. Chief Scientists: Lissa MacVean, Jessie Lacy. Deployment of moored, autonomous instruments data of field activity I-D1-11-SF in North shore of San Pablo Bay from 01/31/2011 to 02/04/2011
Location North shore of San Pablo Bay
Summary Moorings to collect time-series data, and shipboard sampling during the deployment to collect calibration samples for optical measurements of suspended sediment concentration, and to sample bed sediment grain size and other characteristics.
Info derived Flow velocities, salinity, temperature, depths, suspended sediment concentrations; grain sizes in suspension and on the bed, bed porosity, water content, and erodibility; wave characteristics.

Grain-size distributions from San Pablo Bay, California, 2011 to 2012 samples Sediment cores were collected from San Pablo Bay, in the Sacramento-San Joaquin Delta in California by the U.S. Geological Survey Pacific Coastal and Marine Science Center (PCMSC) during multiple surveys from 2011 to 2012. The cores were analyzed for grain-size distributions at the PCMSC sediment lab. Joanne C. T Ferreira
Hydrodynamic and sediment transport data from San Pablo Bay (northern San Francisco Bay), 2011-2012 tripod The U.S. Geological Survey Pacific Coastal and Marine Science Center collected data to investigate sediment dynamics in the shallows of San Pablo Bay in two deployments: February to March 2011 (ITX11) and May to June 2012 (ITX12). This data release includes time-series data and grain-size distributions from sediment grabs collected during the deployments. During each deployment, time series of current velocity, water depth, and turbidity were collected at several stations in the shallows, and one station in the channel. Velocity and depth (pressure) were collected at high frequency (10 Hz) to allow calculation of wave parameters and turbulence statistics. Joanne C. T Ferreira
