Time:            Tuesday March 17, 12:45 – 13:05
Venue:         South Gallery Room 5

Unique in situ gas release experiments could be realized within the CLIMIT demonstration project ACT4storage (Acoustic and Chemical Technologies for environmental monitoring of geological carbon storage) funded by Gassnova together with industry partners and managed by the Norwegian Geotechnical Institute (NGI) in Norway.


During a near shore experiment conducted in 2019 in the Oslo Fjord at 60 m water depth various acoustic and chemical sensors were used for a comprehensive monitoring of CO2 and air bubble plumes from stationary and mobile platforms. This presentation will focus on the discussion of unique datasets obtained with various state-of-the-art active acoustic sensors, vessel-borne and seabed lander based. This data provides a good basis to discuss differences in various active acoustic sensor technologies (single beam-, multibeam echo sounder; sonar) and investigate differences in their suitability for gas plume mapping, monitoring and quantification.

KONGSBERG WILL GIVE SEVERAL PAPERS DURING OI:

  • Vegard Haugen
