| Definition | A custom-designed pCO2 sensor, developed by the National Oceanography Centre Southampton in collaboration with the University of Southampton. The sensor is based on an immobilised indicator entrapped in a polymer membrane alongside a fluorescent reference compound. The indicator fluorescence is altered according to the partial pressure of CO2 of the seawater. This instrument uses a sensing spot from PreSens GmbH which is attached to the fibre optic cable head. Custom-made electronics (Sensoptics Ltd. SGS 42000) and dedicated software (Sensoptics Photon Counter V1.2) are used to record the fluorescence decay curve. The optode measures at a rate of 0.0028 Hz. pCO2 is measured with an uncertainty of +/- 0.0917 micro atm. More information may be found in https://eprints.soton.ac.uk/384569/. | ||
