Description:
Abstract:
This section of the data release contains photographs of 41 vibracores that were collected aboard the R/V Bold Horizon in 2018 on U.S. Geological Survey Field Activity 2018-638-FA offshore Oceanside to San Diego, southern California.
Purpose:
The U.S. Geological Survey (USGS) created continuous line-scan photos of vibracores collected in 2018 offshore Oceanside, southern California. The goal of the vibracore imaging was to provide detailed subsurface sediment characterization to assess sand and gravel resources in Federal and State waters for potential use in future beach nourishment projects along stretches of the coast where critical erosion hotspots have been identified. This cruise was funded through partnerships with the Bureau of Ocean Energy Management (BOEM) and the State of California Ocean Protection Council (OPC).

41 cores were collected on cruise 2018-638-FA with a Rossfelder P-5 vibracorer.
Process_Date: 20180526
Process_Step:
Process_Description:
A Geotek GeoScan V Linescan Imaging system was used to collect line-scan images at resolutions of 25 micrometer pixel widths. Polarizing filters on the camera lens and the LED lamp lights were used to reduce glare effects for wet split-cores. 42 photograph files were created for 41 vibracores (core OC36 is in two sections). The images include a composite ruler that was added using the “Add Ruler 1.4” Geotek software. The camera is calibrated for color balance before each use. The images were collected with a 10-millisecond exposure time, aperture setting of F8.0, and a resolution of 100 pixels per centimeter. An image-specific metadata file was automatically created by the Geotek software for each photograph, providing information on color calibration, pixel dimensions, physical dimensions, and camera settings.
