Methods of acoustic gas flux inversion—Investigation into the initial amplitude of bubble excitation
Methods of acoustic gas flux inversion—Investigation into the initial amplitude of bubble excitation
Passive acoustic inversion techniques for measuring gas flux into the water column have the potential to be a powerful tool for the long-term monitoring and quantification of natural marine seeps and anthropogenic emissions. Prior inversion techniques have had limited precision due to lack of constraints on the initial amplitude of a bubble's excitation following its release into the water column (𝑅𝜀0𝑖). 𝑅𝜀0𝑖 is determined by observing the acoustic signal of bubbles released from sediment in a controlled experiment and its use is demonstrated by quantifying the flux from a volcanic CO2 seep offshore Panarea (Italy), improving the precision by 78%.

Abstract
Passive acoustic inversion techniques for measuring gas flux into the water column have the potential to be a powerful tool for the long-term monitoring and quantification of natural marine seeps and anthropogenic emissions. Prior inversion techniques have had limited precision due to lack of constraints on the initial amplitude of a bubble's excitation following its release into the water column (𝑅𝜀0𝑖). 𝑅𝜀0𝑖 is determined by observing the acoustic signal of bubbles released from sediment in a controlled experiment and its use is demonstrated by quantifying the flux from a volcanic CO2 seep offshore Panarea (Italy), improving the precision by 78%.

Funding Information:
Funding was provided by the European Union’s Horizon 2020 research and innovation programme under the Grant No. 654462 (Strategies for Environmental Monitoring of Marine Carbon Capture and Storage). We would like to thank Michele Deponte, Emiliano Gordini, Diego Cotterle, Valentina Esposito from the Italian National Institute of Oceanography and Applied Geophysics for their logistical support and the scientific divers Andrea Fogliozzi and Martina Gaglioti. We are grateful to the European carbon dioxide capture and storage laboratory infrastructure (ECCSEL)—NatLab Italy of Panarea, an ECCSEL-European Research Infrastructure Consortium infrastructure of Istituto Nazionale di Oceanografia e di Geofisica Sperimentale, without whom our field work would not have been possible. We thank John Davis for his contributions to the lander design and fieldwork.
