Properties of sediment collected from two marshes and adjacent shallows in Northern San Francisco Bay, California, 2022-2023 Gomex Core Bed sediment samples were collected from the intertidal, and subtidal shallows of San Pablo Bay National Wildlife Refuge and Corte Madera Bay near stations where instrumented platforms that were collecting hydrographic time-series were deployed. Sediment sediments were collected with push cores, either manually or by subsampling a Gomex box corer. Cores, which ranged in length from 5 to 18 centimeters (cm), were sectioned by depth. The top two sections from each core were 0.5 cm thick, the following sections were 1 cm thick, sections below 6 cm were often sectioned either into sections that were 1 or 2 cm thick. Additional samples were taken from sediment deposited on ceramic tiles attached to the marsh surface. Samples were analyzed for sediment properties including bulk density, particle size distribution, loss on ignition, and percent carbon. Samantha C McGill

Discharge measurements from transects of a tidal creek in Corte Madera Marsh, Northern San Francisco Bay, California, during 2022 and 2023. RiverPro ADCP Tidal creek discharge was measured repeatedly over diurnal tidal cycles in a tidal channel located in the central, Muzzi marsh region of Corte Madera marsh, California during the summer of 2022 and during the winter of 2023. These transect data were collected using a downward-looking Teledyne RDI RiverPro 1200-kilohertz acoustic Doppler current profiler (ADCP) from a moving boat. Samantha C McGill
CTD profiles from a tidal creek in Corte Madera Marsh, Northern San Francisco Bay, California, 2022-2023 CTD - RBR CTD profiles were collected by the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center to measure the physical characteristics of Corte Madera tidal creek over the course of a tidal cycle during one of the largest spring tides in both Winter and Summer. Conductivity, temperature, and pressure data were collected, as well as suspended-sediment concentration in the water column. Each profile was collected from surface to bed. Profiles were collected on 4 days: August 8 and 9 of 2022 and January 19 and 20 of 2023. Data files are grouped by season (summer or winter). Samantha C McGill
Hydrodynamic time-series data from two marshes and adjacent shallows in Northern San Francisco Bay, California, 2022-2023 CTD - RBR 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 at shallow subtidal and intertidal sites in Corte Madera Bay and San Pablo Bay National Wildlife Refuge (SPNWF) in San Francisco Bay, CA, as well as on the marsh plain of SPNWF marsh and in a tidal creek and on the marsh plain of Corte Madera Marsh, in 2022 and 2023.

Suspended sediment concentrations from water samples collected from the shallows and a tidal creek of Northern San Francisco Bay, California, 2022-2023 watersamples Water samples were collected in San Pablo Bay, Corte Madera Bay, and a tidal creek in Corte Madera Marsh between April 2022 and June 2023 to measure suspended-sediment concentrations and percent carbon of suspended sediment. The water samples were collected near the USGS instrument platforms (see time-series data page) with a peristaltic pump, via a Niskin sampler, or directly with a sample bottle. Samantha C McGill

Topographic data from two marshes and adjacent shallows in Northern San Francisco Bay, California, 2022-2023 Trimble R10 Topographic data were collected in the Corte Madera Marsh, San Pablo National Wildlife Refuge Marsh, and at the time-series stations in the shallows adjacent to each marsh in Northern San Francisco Bay between April 2022 and September 2023. The topographic data were acquired using global satellite navigation system receivers that were either mounted on backpacks and hiked over the marsh surface or mounted on a survey rod held shipside against a deployed platform or on the water surface. Sometimes an additional staff was used in conjunction with the shipside survey rod to reach the platform, which we refer to as an integrated collection method. Samantha C McGill
