attribute NC_GLOBAL summary String Ocean Networks Canada is a not-for-profit society that operates and manages innovative cabled observatories on behalf of the University of Victoria that supply continuous power and Internet connectivity to various scientific instruments located in coastal, deep-ocean, and Arctic environments. Oxygen data are collected by Aanderaa Optode 3830 (S/N 910) (deviceid=12110) from a fixed subsurface vertical profiler (as defined in NERC 2.0 Collection L06 Version 13) on the upper continental slope of Barkley Canyon, a submarine trench that contains exposed gas hydrates and their associated ecosystems. The Aanderaa Optode determines the in-situ oxygen concentration based on the ability of the sensing foil (platinum porphyrine) to act as a dynamic fluorescence quencher. The Optode excites its sensing foil by exposing it to a modulated blue-green light source, and due to its fluorescent behaviour, the foil then returns red light. The lower wavelength photon that is emitted is delayed by the presence of oxygen molecules, and the amount of oxygen determines the lag in time (or phase shift) between excitation of the foil and detection of the returned red light. By linearizing and temperature compensating this phase shift, the absolute oxygen concentration can be determined. Note that while the device was deployed in July, data collection did not begin until August 8th. For more information on the device see
