The donated data were collected aboard the R/V Rachel Carson, which is owned and operated by the Monterey Bay Aquarium Research Insitute.
The goal of this part of the Cal DIG I study is to collect overlapping multibeam bathymetric and Chirp seismic-reflection data Chirp offshore of south-central region of California for the purpose of improving regional models of seafloor (benthic) habitats, sediment transport, and assessing potential geologic hazards.
