Purpose: A sediment geochemical sourcing study was carried out in San Francisco Bay, its local tributaries, and inland rivers to explore the relative importance of fine sediment inputs from local versus inland watersheds. The availability of sediment from local watersheds is an important consideration for wetland habitat restoration and coastal resilience planning because sediment loads from inland watersheds are decreasing and relative water levels are increasing. Supplemental_Information: Surface sediment from San Francisco Bay was collected by the San Francisco Estuary Institute Regional Monitoring Program (RMP) in August 2011 (14 sites with Sample_ID beginning in RMP). Additional information about USGS field activities from which data were derived is available online at: http://cmgds.marine.usgs.gov/fan_info.php?fan=S710SF http://cmgds.marine.usgs.gov/fan_info.php?fan=S0112SF Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government.

Browse_Graphic_File_Type: JPEG Data_Set_Credit: Don Woodrow collected single hand-grab samples from stream banks or stream beds of local and inland tributaries in March and April 2010. Angela Tan analyzed sediment grain size distributions at the USGS Pacific Coastal and Marine Science Center Sediment Laboratory. Elemental chemistry analyses were performed by AGAT Laboratories under contract to the Analytical Chemistry Project of the USGS Geology, Geophysics, and Geochemistry Science Center (GGGSC). GGGSC staff performed QA/QC checks. Native_Data_Set_Environment: Geochemical data are tabulated in comma separated variable (CSV) format. Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: For sediment grain size analyses (GSA), the laser particle counter was calibrated with three manufacturer-provided standards every day. Process duplicates for GSA were analyzed every 20 samples and were within 15 percent. For elemental chemistry determinations, long-term internal reference materials were used to standardize the data. The percent recovery for all elements was within 15 percent of reference values for concentrations that were not less than five times the limit of detection. Logical_Consistency_Report: No formal logical consistency tests were conducted. Completeness_Report: Sample collection depths were not determined for 14 samples collected by RMP. Grain size distribution (percent fines) was not analyzed in CB_598 or tributary samples collected in 2012 and 2013. Thirty size sandy samples out of 143 total had insufficient fine material for multi-acid analysis of elements: potassium (K), sodium (Na), arsenic (As), beryllium (Be), bismuth (Bi), cadmium (Cd), indium (In), lithium (Li), manganese (Mn), molybdenum (Mo), niobium (Nb), phosphorus (P), scandium (Sc), thallium (Tl), tungsten (W), and zinc (Zn).

Lineage: Process_Step: Process_Description: SEDIMENT COLLECTION. Single hand-grab samples were collected from local streams and inland rivers in March and April 2010. Surface sediment from the shoals and ebb tide delta of San Francisco Bay was collected in January 2012 using a benthic grab sampler deployed from the USGS research vessel Parke Snavely. Single hand-grab samples were collected from Petaluma River in March 2012 and inland rivers in February 2013. Process_Date: 20130209 Process_Step: Process_Description: SEDIMENT GRAIN SIZE ANALYSIS. Sediment grain size distributions were determined at the USGS Pacific Coastal and Marine Science Center Sediment Laboratory. To remove organic material, 10 milliliters of 35 percent hydrogen peroxide were added to 20 grams of sediment. The sample was heated to 250 degrees Celsius to remove any remaining hydrogen peroxide and was placed in an ultrasonic bath to liberate the less than 0.063 millimeter-diameter fine fraction. The sample was centrifuged for 1.5 hours in deionized water to remove soluble salts. Samples were funneled through 2 millimeter- and 0.063 millimeter-diameter mesh sieves to separate gravel-sized (greater than 2 millimeter), sand-sized (0.063 to 2 millimeter), and mud-sized (less than 0.063 millimeter) particles. The sand and gravel fractions were dried at 80 degrees Celsius and weighed. Five milliliters of sodium hexametaphosphate were added to the mud fraction and a 20-milliliter aliquot was taken from a 1-liter graduated cylinder to determine the weight of the mud. The particle-size distribution of the mud and sand fraction was analyzed separately using a Beckman Coulter LS 13 320, and the gravel, sand, and mud results were integrated into a single grain-size distribution for each sample.

Bulk sediment was oven-dried at 60 degrees Celsius and disaggregated gently with a mortar and pestle to avoid changing grain sizes. Disaggregated sediment was dry-sieved through stainless steel sieves to obtain 2 grams of the less than 0.063 millimeter fine fraction. Fine sediments were sent to the Analytical Chemistry Project of the USGS Geology, Geophysics, and Geochemistry Science Center (GGGSC), which contracted SGS Inc. Laboratory for analyses of major, minor, and trace element contents using two methods: a near-total four-acid digestion (labeled multi-acid in the table of data) and a total digestion with a sodium peroxide fusion (labeled fusion in the table of data) for elements hosted in acid-resistant minerals. Quantification was performed by inductively coupled plasma atomic emission spectroscopy (ICP-OES) for major and some minor elements and by inductively coupled plasma mass spectroscopy (ICP-MS) for some minor and all trace elements.
