Underwater Video Camera (SCUVA) (IMAGE) Marine Biological Laboratory Caption MBL Whitman investigator John Costello of Providence College (L) and Kakani Young of WHOI (R) test the SCUVA (underwater video) system off of Friday Harbor in Puget Sound, Washington. The system uses a laser beam, fitted with optics that flatten the beam into a paper-thin sheet, to illuminate a single layer of the free-floating natural particles found throughout the ocean. When an animal moves through the flattened beam, a high-definition camera captures what is essentially a cross-section of the animal, displacing the particles as it swims.
