Context
Subocean is a new generation of dissolved gas sensor. Precise measurements with ultra-fast response time are the result of an innovative method of gas extraction using membranes. OFCEAS laser spectrometry allows in-situ measurement of multiple gas concentrations and isotope ratios down to the ocean floor. The data provided in real time allows instantaneous interpretation and high-resolution profiling.
Technology
- Laser spectrometer technology
- Unique membrane gas extraction system
- Battery or cable power supply
- Real-time communication for data visualization
- Works in deep water
- Analysis of methane, carbon dioxide, isotopes, multi-gas
Advantages
- Easy to install and deploy
- Immediate overview enables decisions to be made in situ
- High resolution allows measurements from low gas concentrations
- Possibility of integrating laboratory equipment for discrete analyses
- Possibility of integration on an AUV or ROV
- Continuous 3D profiling
State of progress
Demonstrator used in the Svalbard Arctic Ocean with excellent detection results.
Applications
- Oil and gas: Prospecting new areas, offshore leak detection, methane hydrate studies
- Environmental monitoring: geochemical characterization of the origin of hydrocarbons, study of oil pollution in a groundwater table, monitoring of dissolved gases
- Industry: study of industrial processes of treatment or chemical reaction involving living matter
