2020-09-09· Currently available methane and hydrocarbon sensors are based on gas extraction from water, which undermines response time and selectivity. These devices are also incompatible for integration into AUVs and must instead be installed on large vessels or gliders.
2016-03-08· Dozens of scientists from the University of Colorado, the University of Michigan, NASA, and NOAA deployed methane sensors on airplanes and roving vans with the goal of finding the sources of the hot spot. At the same time, the operators of Japan’s Greenhouse Gases Observing Satellite (GOSAT) pointed a sensor toward Four Corners in order to observe the methane emissions from space ...
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 ...
OEM. Gascard NG is an OEM sensing solution, for measuring either Methane (CH₄) or Carbon Dioxide (CO₂) having been designed for easy integration by system integrators. Available to measure 0-100% or 0-30% of CO and 0-30% of CO₂, the sensor features on board Barometric Pressure Correction, and extensive Temperature compensation.
In my own lab, we’re especially interested in finding ways to power sensors underwater. So, working with WHOI Engineer Jason Kapit, we are investigating ways to scale up our extraction processes.” Once the methane is in gas form, the system combusts the gas to drive an engine and generator. This is a common approach to converting chemical ...

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. Now the METS sensor has been incorporated into the Amerigo ...
Due to their narrow line-width, the Tunable Diode Laser Detectors have a high accuracy and an ideal selectivity for methane molecules. In addition, they feature a large dynamic range covering background partial pressures up to 40 matm.
2014-01-01· Abstract The monitoring of concentration of methane dissolved in water is important for the security of underwater pipelines, delineation of oil and gas fields, and optimization of proper location of oil and gas wells. The reported system consists of metal oxide gas sensor separated from water by hydrophobic pervaporation membrane.
2019-08-13· Methane (CH 4) in marine sediments has the potential to contribute to changes in the ocean and climate system. ...
