Description:

Abstract:

This data release provides radiocarbon measurements from 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:

The age and associated error of the radiocarbon ages are calculated from the fraction modern and its error and the ages are reported according to conventions that the radiocarbon community has adopted. The Conventional Radiocarbon Age is always reported rounded (the NOSAMS convention is reported at https://www2.whoi.edu/site/nosams/calculations-and-reporting-of-results). The fraction modern values and the ages are listed in this data release, so there can be no misinterpretations of these data. The age for the calibration (not rounded) can be calculated using -8033 multiplied by the log normal of the fraction modern.

Logical_Consistency_Report:

Data were checked for logical consistency by the NOSAMS staff before release, and by the USGS staff compiling this data release, to confirm that numerical values were not outside a reasonable range for a particular field.

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.

Lineage:

Process_Step:

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:

Samples of benthic foraminifera or molluscan shell fragments for radiocarbon dating were measured by accelerator mass spectrometry (AMS) at the National Ocean Sciences AMS (NOSAMS) Facility of Woods Hole Oceanographic Institution. The radiocarbon ages were obtained by a ratio of 14C to 12C using a 14C half-life of 5568 years (Stuiver and Polach, 1977) and then were converted to calibrated calendar ages (cal years AD) using the CALIB 8.2 program (Stuiver and Reimer, 1993; website accessed in 2022 and 2023) and the Marine20 calibration curve (Heaton and others, 2020). The calibrated ages are reported as the median probability ages at the 95 percent confidence level (2 sigma range). A regional reservoir-age correction (delta R), as defined by Ingram and Southon (1996), of 22 plus or minus 1 years was used for both the benthic foraminiferal and molluscan shell fragment samples based on the delta R used by Watt and others (2022) in nearby San Pablo Bay.
