Main Endeavour Field South Underwater Ultraviolet Raman Spectrometer Deployed 2018-06-27

The SIDSSE Underwater Ultraviolet Raman Spectrometer (UURS) 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 Ultraviolet Raman Spectrometer. The Underwater Ultraviolet Raman Spectrometer (UURS) is a sensor used to measure concentrations of dissolved chemicals directly from their ultraviolet absorption spectrum. A variety of chemicals absorb light in the UV, and each of these chemicals has a unique absorption spectrum. Concentration of these chemicals can be determined directly, with no chemical manipulation, by measuring the absorption spectrum of seawater in the UV and then deconvolving the spectra to yield the concentration of each component. 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.
