The tow-yo at East Diamante submarine volcano revealed intense plumes near the summit. The black dots trace the track of the CTD as it is towed through the water column. This image is vertically exaggerated by 11 times. Hydrothermal plumes are indicated by the distribution of particles (measured in units of NTU) over the submarine volcano. The most intense plumes are seen here as yellow, red and brown colors. The plume here is aproximately 10 times more intense than the plume observed earlier over the back-arc spreading center.
