Bubble plume

3D animation in which viewer circles around a stationary bubble plume imaged in the water column. The bottom of the bubble plume is at a water depth of about 35 meters (green in animation) and the top at a depth of about 8 meters (red in animation). This technique cannot image bubbles near the surface because water this shallow is beyond the outer beams of the multibeam sonar. The background is a digital elevation model of Santa Cruz, which shows the shape of the land but no structures or vegetation.
