NOAA PMEL, University of Washington and OptoKnowledge Systems, Inc. (OKSI) successfully conducted the first deep water test of a new methane analyzer to measure the concentration and carbon isotope ratio of methane near Axial Seamount. This new instrument can collect data that will improve scientists’ understanding of carbon cycling, greenhouse gasses, and sub-seafloor chemosynthetic reactions.
After 3 years of testing and development, the analyzer was mounted on the remotely operated vehicle Jason and coupled to PMEL’s hydrothermal fluid and particle sampler (HFS) during a recent cruise on the Research Vessel Thompson.
