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
