This dataset consists of 14 magnetotelluric (MT) stations collected in 2015 near San Pablo Bay, California along a east-northeast profile. The U.S. Geological Survey acquired these data to understand the fault geometry of the Hayward Fault and the Rodgers Creek Fault.

Included here are the model, data, and reponse files used to create the 2D electrical resistivity model. Plots of the data and model response are provided as well as one of the model. The data, model, mesh, regularization, and response files are provided in Occam2D format. See https://marineemlab.ucsd.edu/Projects/Occam/2DMT/index.html for details on file format. This data product includes Occam2D data, model, response, and mesh files such that anyone can reproduce the model results. To produce the 2D model the data are rotated to principle strike direction estimated from the phase tensor azimuth, which was nominaly geomagnetic north. The station locations are projected onto a profile line N66E. Bad data points...
A Gust erosion chamber was used to apply horizontal shear stress to sediment cores obtained from San Pablo and Grizzly (within Suisun) Bays in California. A pair of sediment cores were collected from the same approximate locations in each bay six times between June 12th, 2019 and August 15th, 2019 for a total of 12 experiments and 24 sediment core results. Locations were chosen to capture the benthic variability along the estuarine salinity gradient, are established benthic monitoring stations, proximity to historic/restored wetlands, and practicality for field operations. Sampling dates targeted spring and neap tide conditions. An onshore experiment was conducted on each core to apply shear stresses with stepwise...

The Hamilton Wetland Restoration Project (HWRP) is a joint venture between the US Army Corps of Engineers (USACE; San Francisco District) and the California State Coastal Conservancy. The site is located on the property of the former Hamilton Army Airfield in Novato, California, along the western edge of San Pablo Bay, which is part of northern San Francisco Bay. The initial stages of wetland restoration, which included dredged sediment reuse, took place during 2009–2011. From 2011 until April 2014, the site was maintained as partially flooded through a temporary one-way culvert that allowed bay water onto the site. On April 25th, 2014, the outboard levee towards the north-eastern corner of the site was breached...

We performed bathymetric surveys using a shallow-water echo-sounding system (Takekawa et al., 2010, Brand et al., 2012) comprised of an acoustic profiler (Navisound 210; Reson, Inc., Slangerup, Denmark), Leica RTK GPS Viva rover, and laptop computer mounted on a shallow-draft, portable flat-bottom boat (Bass Hunter, Cabelas, Sidney, NE; Figure 7). The RTK GPS obtained high resolution elevations of the water surface (reported precision 10 cm water depth. We recorded twenty depth readings and one GPS location each second along transects spaced 100 m apart perpendicular to the nearby salt marsh. We calibrated the system before use with a bar-check plate and adjusted the sound velocity for salinity and temperature differences....

Hydrodynamic and sediment transport time-series data, including water depth, velocity, turbidity, conductivity, and temperature, were collected by the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center within two embayments of San Francisco Bay. Data were collected in San Pablo Bay and Grizzly Bay from June to August 2019 at seven unique stations. Data files are grouped by area (shallows of San Pablo Bay, channel of San Pablo Bay, and shallows of Grizzly Bay). Each shallow site contained a variety of sensors located on two tripods and one surface mooring, while the channel site consisted of one tripod. Users are advised to assess data quality carefully, and to check metadata for instrument information,...

These data present suspended particle size distributions collected by the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center within two embayments of San Francisco Bay. Data were collected at one site in San Pablo Bay and one site in Grizzly Bay from January through February 2020 by deploying a Sequoia Scientific Laser In-situ Scattering and Transmissometry instrument (LISST 200x) from a small vessel near pre-established USGS instrument moorings. At both sites, data were collected on four dates at three depths, generally near the water surface, at mid depth, and near the sediment bed, for 1-3 minutes at each depth. LISST volume concentrations are most accurate when the optical percent transmission...

Water samples were collected in San Pablo Bay and Grizzly Bay on five days from January through June 2020. The water samples were collected from a small vessel near pre-established USGS instrument moorings using a peristaltic pump or a Niskin bottle. Data are provided in a comma-delimited values spreadsheet.

A 1-m resolution, continuous surface, bathymetric digital elevation model (DEM) of the northern portion of San Francisco Bay, which includes San Pablo Bay, Carquinez Strait, and portions of Suisun Bay, was constructed from bathymetric surveys collected from 1999 to 2016. In 2014 and 2015 the California Ocean Protection Council (OPC) contracted the collection of bathymetric surveys of large portions of San Francisco Bay. A total of 93 surveys were collected using a combination of multibeam and interferometric side-scan sonar systems. Of those 93 surveys, 75 consist of swaths of data ranging from 18- to just over 100-meters wide. These swaths were separated by data gaps ranging from 10- to just over 300-meters wide....

Bed sediment samples were collected in San Pablo Bay and Grizzly Bays on eight days from June through November 2019, to analyze for sediment properties including bulk density, particle size distribution, and percent organic carbon. Sediment samples were collected from a small vessel near pre-established USGS instrument moorings using a Gomex box corer that was subsampled with three push cores (37 mm in diameter) per Gomex core. Six subsamples were collected from the top 5 centimeters (cm) of each push core, a few push cores included the top 8 cm. The top two subsamples were each 0.5 cm thick, and all following subsamples were each 1 cm thick. Push core samples from the first, third, and fifth centimeter depth were...

Surface sediment samples from the North San Francisco Bay-Delta Estuary were collected monthly at five stations located west of Rio Vista and east of Point Pinole. Sediment was collected near Montezuma Slough, Chips Island, the Concord Naval Weapons Station, Carquinez Strait near Martinez, and San Pablo Bay at water depths ranging from 6.5 to 14.3 meters. Samples were collected coincident with water-quality measurements (Cloern and Schraga, 2016) and metal concentrations in filter-feeding bivalves (Brown and Luoma, 1995; Stewart et al., 2013). Depending on the station, the period of record ranges from 13 to 24 years, from December 1993 to September 2017. Samples were sieved to <64 µm to eliminate grain-size bias...
