The Sea-Bird Thermosalinograph SeaKeeper (SN 18) was deployed on 2023-01-13 on Tsawwassen - Duke Point Ferry Route. This ferry route goes between Tsawwassen terminal in Vancouver, BC and the Duke Point terminal, Nanaimo BC. This device is a Thermosalinograph. Thermosalinographs collect data from the sea surface via flow-through systems on vessels. Typically they are mounted near the front of the vessel in order to minimize contamination. Primary variables measured are temperature and conductivity, and other variables like salinity and density are derived. It was deployed on a mobile 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.
