The Sea-Bird Microcat SBE37SMP-ODO 16834 was deployed on 2020-04-22 at Boundary Pass. Boundary Pass is a strait located along the boundary between Washington State and British Columbia. It connects Haro Strait with the Strait of Georgia. 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.
