Water pressure/depth and turbidity time-series data from CHC14 Marsh and mudflat stations in San Pablo Bay and China Camp Marsh, California Moorings - Tripods 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. Jessica R Lacy

Sediment size distributions from San Pablo Bay and China Camp Marsh, California Van Veen As part of the hydrodynamic and sediment transport investigations in San Pablo Bay and China Camp Marsh, California, particle size distributions of bed sediments were measured at most instrumented stations and are presented in a comma-delimited values spreadsheet. This portion of the data release presents San Pablo Bay and China Camp Marsh sediment particle size distributions from samples collected during multiple instrument deployments. Users are advised to check the data carefully for sampling time, location, and reference information. Jessica R Lacy
Seasonal vegetation characteristics in a Spartina foliosa- and Salicornia pacifica-dominated salt marsh at China Camp State Park Moorings - Tripods As part of the San Francisco Bay Marsh Sediment Experiments and hydrodynamic investigations in San Pablo Bay and China Camp Marsh, California, vegetation sampling measurements were taken over several periods at numerous locations. This portion of the data release presents physical characteristics and percent cover data from vegetation plots sampled in China Camp State Park salt marsh (northern San Francisco Bay) in 2015, 2016, and 2017. One-meter quadrats (1m x 1m) were analyzed for percent cover of each vegetation species present, average canopy height, and maximum canopy height. The percent cover was done by visual inspection. A quarter-meter quadrat (0.25m x 0.25m) was then used for stem count and stem diameter measurements. Stem counts were only done for S. foliosa. These quadrats ran along the instruments used to collect sediment and hydrodynamic data, which is described elsewhere in this data release. This survey was conducted on January 23, 2015 (winter conditions) and again on June 6, 2016 (summer conditions). A separate survey was conducted on September 29, 2016 and May 3, 2017, to measure the length, width, and spacing of S. foliosa leaves. Data collected are provided as a comma-delimited spreadsheet (.csv). Jessica R Lacy
