Online_Linkage: https://doi.org/10.5066/P1XZFGCX Description: Abstract: 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. Purpose: These data were collected to calibrate turbidity data from optical backscatter sensors to suspended-sediment concentration and to quantify the carbon content suspended sediment in Corte Madera Marsh tidal creek. These data were collected as part of a study with the goal to produce information useful for prioritizing marsh restoration sites, assessing restoration actions, and understanding mechanisms of sediment delivery to marshes. These data are intended for researchers, students, policy makers, and the general public.

Completeness_Report: Dataset is considered complete for the information presented, as described in the abstract.

Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Horizontal accuracy derived from GPS instrumentation is better than 5 meters (m). Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: No formal positional accuracy tests were conducted. Pumped samples were collected with the intake valve at a fixed height on the sampling frame either resting on the seabed or suspended from the vessel. Samples collected via Niskin and/or grab methods have poorer positional accuracy as the Niskin sampler and bottles used for the grab method have larger diameters, ranging from 10.2 centimeters (cm) to 5.2 cm for the Niskin sampler and grab bottles, respectively. Lineage: Process_Step: Process_Description: Water samples were collected periodically between April 2022 and June 2023 using a peristaltic pump, Niskin bottle, or sample bottle. Sampling positions were recorded using a hand-held global navigation satellite system (GNSS) receiver. Samples were placed in cold storage until processed. Process_Date: 20230602 Process_Step: Process_Description: The suspended sediment concentrations of the samples were determined in the USGS Pacific Coastal and Marine Science Center sediment lab. Suspended sediment concentrations were determined by a filtering a known, subsampled volume of sample through a pre-weighed filter, which is then dried and reweighed to determine the mass of suspended sediment on the filter. Suspended sediment concentrations were calculated by subtracting the weight of the filter from the weight of the reweight (post filtering) filter. The resulting weight (in milligrams) is divided by the volume of sample filtered (in liters) to get the concentration of suspended sediments. Process_Date: 20230615 Process_Step: Process_Description: The suspended sediment carbon analysis was performed by the PCMSC sediment and carbon labs employing a coulometric titration technique described in Engleman and others (1985) and UIC operating manuals for the UIC CM5200 autosampler furnace, the UIC CM5230 acidification module, and the UIC CM5017 coulometer. Total carbon (TC), total inorganic carbon (TIC), total organic carbon (TOC) and percent calcium carbonate (CaCO3) are reported as percent dry weight. Approximately 1 liter of the water-sediment samples were centrifuged to remove the water and concentrate the sediment. The sediment was dried and pulverized and ready to be processed for percent carbon analysis. For TC analysis, the dried samples were weighed and wrapped in an aluminum capsule then combusted at 950 degrees Celsius in an UIC CM5200 autosampler furnace attached to an UIC CM5017 coulometer. The carbon dioxide (CO2) produced by combusting the sample was then converted to TC by the UIC CM5017 coulometer. For TIC, the dried samples were weighed and loaded into an UIC CM5230 acidification module attached to an UIC CM5017 coulometer. The samples were then digested in a perchloric acid solution, and the CO2 generated was measured and converted to TIC. Two analyses per sample were run and the results were averaged. TOC was calculated by subtracting TIC from TC. The TIC value was then multiplied by 8.333 (the molar stochiometric ratio of CaCO3 to C) to convert TIC to percent CaCO3.
