ROV Hercules Catches a Glimpse of a Mola Mola (Ocean Sunfish)

The deep-water biological habitat and geological character of the seafloor around the Channel Islands are poorly understood despite considerable research in the area and a number of special designations in place to protect these regions. Less than 50% of the seafloor within the boundaries of the Channel Islands National Marine Sanctuary (CINMS) has been mapped by high-resolution sonar.
