Instrument Description

CO2 Sensor

CO2 sensors are installed to monitor CO2 levels in the ocean, and how its concentration affects the marine environment. CO2 sensors installed at Ocean Networks Canada measure the partial pressure, or the concentration of dissolved CO2 in seawater by a variety of techniques. Since carbon dioxide molecules absorb infrared (IR) radiation in a characteristic absorption band and specific wavelengths, CO2 is often detected by IR sensors. Sensors are also equipped with calibration mechanisms that provide a zero CO2 measurement each day, which compensates for changes in the performance of sensors during long deployments.
