The water samples were collected near pre-established USGS instrument moorings with a Niskin bottle. Purpose: Percent carbon was measured to characterize carbon fluxes into and out of tidal creeks. The samples were collected as part of a study to quantify sediment fluxes and changes in marsh morphology at Whale's Tail marsh in southern San Francisco Bay. These data are intended for researchers, students, policy makers, and the general public.

All samples were taken along known transects between fixed locations, with trajectory dependent upon current speed and direction. When no GPS was available approximate location was estimated from known equipment location. Logical_Consistency_Report: Data values are within the expected values with the majority of the carbon in the sample of organic origin Completeness_Report: Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Horizontal accuracy derived from GPS instrumentation is less than 5 m. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: No formal positional accuracy tests were conducted. Due to high currents, sample height above bottom is nominal and could not be consistently achieved. Total depth recorded by a handheld range finder approximately +- 20 cm. Lineage: Process_Step: Process_Description: Water samples were collected 12/3/2021, 12/6/2021 and 1/3/2022 during the king tides using a Niskin 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: 20220103 Process_Step: Process_Description: The suspended sediment percent carbon measurements were made in the USGS Pacific Coastal and Marine Science Center sediment and carbon labs. The water-sediment samples were centrifuged to remove the water and concentrate the sediment. The sediment was dried and then pulverized into a fine powder. To obtain percent total carbon (TC), approximately 20mg of the pulverized sample was weighed and wrapped in an aluminum tin. A UIC CM 5200 furnace attached to a CM 5017 coulometer was used to incinerate the samples at 950 degree C which converted the produced CO2 into a value to obtain total carbon as percent dry weight. For percent total inorganic carbon (TIC), approximately 20mg of sample was weighed into capsules and placed in glass sample tubes which were loaded into a UIC CM 5230 acid digester attached to a CM 5017 coulometer. The samples were digested with 2mL perchloric acid and the produced CO2 was measured to obtain a total inorganic carbon value as percent dry weight. To determine percent calcium carbonate of a sample, the percent TIC value was multiplied by 8.333. The percent total organic carbon (TOC) value was determined by subtracting the percent TIC value from the percent TC value. Two analyses were run per system and the results were averaged.
