Data were collected aboard the NOAA (National Oceanic and Atmospheric Administration) Ship Rainier research vessel, funded by the Bureau of Ocean Energy Management (BOEM) in order to adequately address potential impacts in environmental impact statements and environmental assessments under the National Environmental Policy Act (NEPA).
This datasest is one of several collected as part of the California Deepwater Investigations and Groundtruthing (Cal DIG I) project, which focuses on the offshore south-central region of California at water depths of 500 to 1,200 meters, in Federal waters outside of the State of California three nautical mile limit. The goal of study is to conduct a reconnaissance survey of the outer continental shelf of south-central California for the purpose of improving regional models of seafloor (benthic) habitats, assessing geologic hazards, and sedimentary processes. Geophysical and geological data from this project are needed to address important issues associated with marine spatial planning, ecosystem assessments, geohazards, and thereby the potential for alternative energy infrastructure (namely floating wind turbines) offshore south-central California.
