The Sea-Bird SeaCAT SBE19plus V2 7876 was deployed on 2022-05-21 at Endeavour East. This station is located to the east of the Endeavour Hydrothermal Vents, and includes instrumentation near the NEPTUNE observatory Endeavour node. This device is a Conductivity Temperature Depth. Conductivity Temperature Depth (CTD) is an instrument package that contains sensors for measuring the conductivity, temperature, and pressure of seawater. Salinity, sound velocity, depth and density are variables that can be derived from sensor measurements. CTDs can carry additional instruments and sensors such as oxygen sensors, turbidity sensors and fluorometers. 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.
