Transcription de la présentation

  1. <<<<<< Why hydroacoustic • How much gas is being released, when and where • To detect and map the occurrence of bubbling seep sites, gas wells/pipelines

  2. <<<<<< Why hydroacoustic • How much gas is being released, when and where • To detect and map the occurrence of bubbling seep sites, gas wells/pipelines • With no disturbances, remotely, investigate and monitor the activity of bubble release

  3. <<<<<< Why hydroacoustic • How much gas is being released, when and where • To detect and map the occurrence of bubbling seep sites, gas wells/pipelines • With no disturbances, remotely, investigate and monitor the activity of bubble release • Target water column sampling to investigate methane distribution Yoyo CTD at Hydrate Ridge, Southern Summit

  4. <<<<<< Why hydroacoustic • How much gas is being released, when and where • To detect and map the occurrence of bubbling seep sites, gas wells/pipelines • With no disturbances, remotely, investigate and monitor the activity of bubble release • Target water column sampling to investigate methane distribution • Quantify gas fluxes quickly, with a wide coverage and remotely • Methods used: • Singlebeam echosounder systems (single/multi frequency, splitbeam) • Multibeam echosounder systems (quick spatial mapping) • SideScanSonar • Ships, lander, ROV based • Passive acoustics for flux and BSD determination
