Description:

Abstract:

This dataset includes concentrations chloride and sulfate in porewater from piston and gravity cores collected in September 2019 offshore of south-central California aboard the R/V Bold Horizon. 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.

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).

Process_Date: 20190927

Process_Step:

Process_Description:

Porewater samples were collected at intervals throughout each core using porous ceramic tubes connected to an evacuated small volume syringe at one end and inserted into the cores at the other end to extract pore waters through vacuum action. Porewater samples were filtered through 0.22-µmfilters, diluted 1:100, and injected into a Dionex DX-120 ion chromatograph. Bracketing standards were run every five samples. Long-term reproducibility of Cl concentration measurements is 3.2% (2s).
