Three-dimensional perspective of D2 Dive 19 track and waypoints with superposed water column bubble plumes

Detailed Description

Three-dimensional perspective of D2 Dive 19 track (white lines) and waypoints (red points) with superposed water column bubble plumes imaged by NOAA Ship Okeanos Explorer mapping team (multi-colored point clouds). Methane bubble plumes at Norfolk Seeps have been imaged rising over 900 meters (2,950 feet) above the seafloor in some surveys. Bathymetric data were collected with the Okeanos Explorer multibeam sonar and are contoured at 10 meter (about 3 feet) intervals. The locations of previously identified seeps are indicated with white points. All data shown at two times vertical exaggeration.
