underwater methane sensor

Deep sea pH, oxygen and methane sensors on a lander ...

The Franatech dissolved methane and temperature sensor (METS) can measure dissolved methane to concentrations of 50 nM (~%). The high sensitivity of the METS, combined with its high accuracy, means it has been cited in over 200 scientific publications on deep sea projects. These include Seabird CTD devices, moorings, and AUV’s.

High-resolution underwater laser spectrometer sensing ...

derwater CH4 sensors do not have the required response time for accurate high-resolution mapping. For this reason, Gentz et al. (2014) deployed an underwater membrane-inlet mass spectrometer (UWMS) with a fast response time for mapping of CH4 at shallow (10m) depths. Boulart et al. (2013) used an in situ real-time sensor in the Baltic Sea. The ...
