Unlike most of the science instruments (which are loaded onto the front of the remotely operated vehicle [ROV]), the mass spectrometer is bolted down on the back of the Jason. The red arrow is pointing to the location of the mass spec on the Jason. A probe, connected to the body of the instrument, is located on the front of the Jason and is used for measuring dissolved gases. Image courtesy of Expedition to the Deep Slope 2007.
