Measuring Methane At Southern Hyrate Ridge
An in situ, cabled mass spectrometer is installed at a methane seep at the summif to Southern Hydrate Ridge. The OOI-RSN mass spectrometer was built by Peter Girguis, Harvard University. The intake host is on a small tripod and the mass spectrometer is housed inside a titanium housing within a half-size junction box frame. It is installed adjacent to an instrument to measure fluid flow in and out of the seafloor (Mosquito) and an osmo fluid sampler for seep chemistry. Photo credit: NSF-OOI/UW/CSSF; Dive R1772; V14.
