The Tech of Volcano Exploration: Highlights November 13, 2013

This album highlights some of the technology, engineering, and creativity that goes into the measurements and experiments that Hercules is capable of conducting.  During this dive, Hercules used a pH meter to measure the acidity of the water at different depths.  He measured bubble flux using the bubble board, temperature using the temperature probe, and a 2-liter pitcher to measure the volume of bubbles emitted from an active champagne vent.
