MIMS Integrated with a Multiple-Filter Deep Water Filtration System
For the Department of Energy, SRI and partners studied methane hydrate deposits in the Gulf of Mexico.
To coordinate microbe collection with water chemistry measurements, SRI St. Petersburg and the University of Georgia (UGA) Center for Applied Isotope Studies have integrated in situ membrane introduction mass spectrometry (MIMS) technology with a new, high-throughput, multi-filter microbe sampling system. An existing MIMS system has been integrated successfully with a new UGA Lander/multi-filter sampling system, and pressure-tested to a depth of 1,000 meters. At the same time, a new, smaller, lower-power MIMS system is under construction for future deployments.
The multi-filter sampling/MIMS system was deployed at Mississippi Canyon 118 (MC118) in the Gulf of Mexico as part of a larger effort coordinated by the Gulf of Mexico Gas Hydrates Consortium for in situ studies of methane hydrates and the surrounding water column chemistry and biological communities. Methane hydrate is a potential alternative energy source under study by the consortium, the Department of Energy, and other organizations.
This project was funded by the U.S. Department of Energy through the Gulf of Mexico Gas Hydrates Consortium and the University of Georgia, contract numbers RR380-042/4688598 and RR380-043/4692518.
