Wally Land Methane Sensor Deployed 2012-05-31

The Franatech METS Methane Sensor G051-E273 was deployed on 2012-05-31 at Wally Land. Wally Land is a location within Barkley Canyon gas hydrate field, where hydrate dynamics are observed. This device is a Methane Sensor. Methane sensors measure the concentration of dissolved methane in the seawater. Gas molecules diffuse through the membrane to the detector chamber driven by the partial pressure gradient that exists between the chamber and the ambient water. The concentration difference between two solutions is referred to as methane concentration. It was deployed on a fixed platform. Data from this deployment were archived and made available through Ocean Networks Canada's Oceans 3.0 digital infrastructure, with quality assurance and derived data products following established practices.
