The HoloPOD is lowered into the Gulf of Mexico, where data indicated the Deepwater Horizon subsurface oil plume is located. It will image and measure oil droplets that make up the plume. (Photo courtesy of Cabell Davis, Woods Hole Oceanographic Institution)

HoloPOD images taken within the plume include oil droplets (left), a fish egg (center), and a crustacean larva (right). Data on sizes of oil droplets are being used to model the location, depth, and extent of the plume. (Photo courtesy of Cabell Davis, Woods Hole Oceanographic Institution)

Images taken within the plume by Davis' Digital Autonomous Video Plankton Recorder (DAVPR) include a) a live jellyfish, b) marine snow, c) an air bubble, and d) an unidentified small organism. (Photo courtesy of Cabell Davis, Woods Hole Oceanographic Institution)
