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
