This dataset is one of several collected as part of the Bureau of Ocean Energy Management (BOEM)-funded California Deepwater Investigations and Groundtruthing (Cal DIG I) project. The purpose of the study is to assess shallow geohazards, benthic habitats, and thereby the potential for alternative energy infrastructure (namely floating wind turbines) offshore south-central California due to its proximity to power grid infrastructure associated with the Morro Bay power plant. These core data provide information about the geology of the seafloor and shallow subsurface offshore of the south-central California coast. Purpose: This dataset was collected in order to identify shallow geohazards, benthic habitats, and thereby the potential for alternative energy infrastructure (namely floating wind turbines) offshore south-central California due to its proximity to power grid infrastructure associated with the Morro Bay power plant.

No cores were retrieved from sampling site 08GC. 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: The locations of samples were determined using the R/V Bold Horizon's internal Yonav navigation system. No other formal positional accuracy tests were conducted. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: No vertical positional accuracy tests were conducted Lineage: Process_Step: Process_Description: Piston and gravity cores were collected at sea aboard the R/V Bold Horizon on U.S. Geological Survey (USGS) cruise 2019-642-FA in conjunction with the Monterey Bay Aquarium Research Institute (MBARI). The cores were transported back to the USGS Pacific Coastal and Marine Science Center in Santa Cruz, CA, where they were split and photographed using a multi-sensor core logger (MSCL) Geoscan V linescan system. Some of the cores were divided into multiple sections and are indicated as such in the filename. A ruler was added to the TIFF images using the Geotek Add Ruler v.1.4 software, which exported the final TIFF and software-proprietary XML files, adding “R” to the file name. Files have been zipped together by the sampling site name given in the field.
