Description:

Abstract:

This dataset includes photographs (linescan images) of 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.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Quality control of attribute accuracy was conducted during field data collection and processing workflows. 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 CT analyses. Not all segments of the cores were analyzed.

Process_Date: 2023

Process_Step:

Process_Description:

Sediment surfaces were cleaned and smoothed prior to scanning. Linescan images were obtained using a Geotek V Linescan Imaging system mounted to a Geotek Multisensor Core Logger (MSCL). A prime lens with a 50 mm focal length was mounted 38.6 cm above the core surface. Cross polarized light emitting diodes (LED) were used to illuminate the sediment surface. Colors were calibrated in the Geotek Linescan software using an 18 percent gray card, and images were acquired at an aperture of f3.43 and exposure time of 40 milliseconds. TIFFs are provided in 16-bit RGB TIFF format. Scaling information is embedded in the TIFF files and also provided in the associated XML files. File names correspond to the names of the cores within each scan. For example, 'CAR-RC02-0-50cm_001_01.TIF' corresponds to the linescan image of core segments collected during field activity 2022-643-FA,'CAR' refers to the Cargill Marsh, and 'RC-02' to the core location within the marsh. '0-50cm' or '40-90cm' refers to the depth of the core relative to the surface of the marsh. The suffix of '_001_01' is retained from the automatic processing to differentiate photographic from other imagery of the same core. Computed tomography images of these cores are available in a separate section of this data release.
