Online_Linkage: https://doi.org/10.5066/P15AORBR Description: Abstract: This dataset presents core information such as core IDs, core lengths, depth intervals, and locations from sediment cores collected from Cargill Marsh, South San Francisco Bay, California on June 21, 2022, and December 14, 2023. The cores were collected with hand driven push cores to assess sediment accumulation on the marsh. Purpose: These cores were collected to measure sediment accumulation as part of a study to quantify sediment fluxes and changes in marsh morphology on marshes in southern San Francisco Bay. Supplemental_Information: Cores were collected, analyzed, and archived by USGS, Pacific Coastal and Marine Science Center. Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government.

No formal attribute accuracy tests were conducted. Logical_Consistency_Report: No formal logical consistency tests were conducted. 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: A RTK GPS system was used for obtaining latitude and longitude point locations during the field activity with centimeter accuracy. As each core site required two adjacent cores to complete the 90 cm length, the horizontal position accuracy of 50 cm is reasonable. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Core depth values are relative to the top of sediment surface at the time of core collection. Coring-induced compaction, if any, was not determined. No formal vertical accuracy tests were conducted. Lineage: Process_Step: Process_Description: Sediment cores were collected from the marsh environment on Cargill Marsh in Eden Landing Environmental Reserve, Alameda County, California using a Russian corer (a hand-held, side-filling peat auger). At each core site, two adjacent cores holes were used to sample sediment in 50 cm intervals with a 10 cm overlapping section resulting in undisturbed sediment cores of 90 cm length. Cores were transported back to the USGS Pacific Coastal and Marine Science Center for imaging, and subsequently sectioned in two cm samples for Cesium-137 analyses. Not all segments of the cores were analyzed.
