Description:
Abstract:
This data release provides census counts of diatoms in sediments of a core obtained off San Francisquito Creek in South San Francisco Bay.
Purpose:
The urbanized area of downtown Menlo Park is subject to persistent flooding and sediment deposition by San Francisquito Creek in South San Francisco Bay. To mitigate these events, a suite of cores was collected in 2002 at the mouth of the creek to determine sediment depositional rates on the delta. One of those cores was selected for microbiological (pollen, diatoms, and foraminifera) and geochemical analyses to reconstruct a depositional record over the past two millennia. Based on an abrupt change in lithology and faunal assemblages, an instantaneous vertical displacement and deepening of the depositional environment is evident. Coseismic subsidence associated with large fault ruptures may cause these events. An age model based on the first appearances of non-indigenous biota, radiocarbon dates, radiochemistry, and sediment geochemistry suggests the 1868 rupture of the Hayward Fault may have been the cause.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Microscopes are operationally checked every year to assure optics are aligned and visual acuity can be maximized during sorting and identifications. Specimen identifications were compared to reference material (actual specimens and published monographs) to ensure idenfications were accurate. Specimen enumeration (counts) were checked with original laboratory bench sorting sheets to assure numbers were correct, and the sorting and data entry into spreadsheets was rechecked at least once.
Logical_Consistency_Report:
Data were checked for logical consistency by the laboratory staff before release to confirm that numerical values were not outside a reasonable range for a particular field. Cumulative counts of percentage data for the total diatom assemblage had to equal approximately 100% to ensure numbers were reported correctly.
Completeness_Report:
Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the metadata for each part of this data release carefully for additional details.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
A formal accuracy assessment of the horizontal positional information in the data set has not been conducted. The horizontal position was estimated based on distances from the modern tidal channel listed on a figure provided to the first author in October 2003. The horizontal accuracy cannot be determined.

Process_Description:
A metal core barrel, approximately 9 cm in diameter, was driven into the mudflat slightly northwest of Hooks Point on informally named "Hooks Island" in South San Francisco Bay near Palo Alto, California in 2002 to recover a sediment core. The precise coring location is not available. The core was brought to the the USGS facility in Menlo Park, California and housed in a core refrigerator.
Process_Date: 2002
Process_Step:
Process_Description:
Twenty-five samples of approximately 1 cubic cm were obtained from core 721-1 for diatom analysis every 10 cm downcore and every 5 cm from 150-80 cm. Samples were processed using 30 percent hydrogen peroxide, 37 percent hydrochloric acid, and 70 percent nitric acid solutions to remove carbonate and organic matter and a 5 percent sodium pyrophosphate solution to deflocculate the remaining clay. The samples were then washed repeatedly with di-ionized water until neutralized. Approximately 50 microliters of the resulting suspension were dried on a 22 X 30 mm coverslip and permanently mounted using Naphrax. Two hundred frustules per sample were enumerated, using a Leica DM LB2 microscope with Nomarski differential interference contrast optics at magnifications of 630X and 1,000X. Data for some taxa were combined because similar or gradational morphological characteristics prevented species differentiation in some samples. The diatom slides and residues of this study are on file at the U.S. Geological Survey, Menlo Park, California.
