Tests and improvements of the SubOcean probe (SubOcean++)
The project in a nutshell:
The SubOcean probe is an in-situ sensor embedding a laser spectrometer, designed to continuously monitor infrared-absorbing trace gases dissolved in water.
The SENSE lab has acquired two of them: one for CH4 and its stable carbon isotopes, and the other for CH4 and N2O.
Key objectives of the project include testing and improving the probe’s performance, evaluating custom-made gas extraction membranes, enabling surface-powered real-time data control, integrating a 3D positioning system, and developing an ROV extension for monitoring critical area.
