Main Endeavour Field South Underwater Cavity Ring-down Spectroscopy Deployed 2018-06-27

The SIDSSE Underwater Cavity Ring-down Spectroscopy (UCRDS) SN 01 was deployed on 2018-06-27 at Main Endeavour Field South. Main Endeavour Field South is at the south end of the Main Endeavour Field located along the Endeavour Ridge, where hydrothermal vent systems are observed. This device is a Underwater Cavity Ring-down Spectroscopy. Underwater Cavity Ring-Down Spectroscopy (UCRDS) is a highly sensitive optical spectroscopic technique that enables detection of trace gases in water by measuring the change of the monoexponential ring-down time attributable to the additional optical loss of an absorbing gaseous species present in the sample cavity. It was deployed on a fixed platform. Data from this deployment were archived and made available through Ocean Networks Canada's Oceans 2.0 digital infrastructure, with quality assurance and derived data products following established practices.
