Detailed Description

The water column plumes are shown above the sub-seafloor structure as imaged by high-resolution multichannel seismic data acquired by the USGS and processed by J. Kluesner. (Bottom) Close-up view showing that the bubbles in the largest methane plume is detectable more than 900 meters (2950 feet) above the seafloor.
