A perspective view of the several eruption cones inside the East Diamante caldera. Our CTD tow (black sawtooth line) mapped out a plume of particles carried southeast from the Black Forest vent field by the local currents (yellow arrow). The scalebar on the bottom left corner of the image indicates the nephelometric turbidity units, an optical measurement of the particles in the water, which indicates the location and intensity of the hydrothermal plume. The scalebar at the bottom right shows the bathymetry depths at the top of the volcano.
