Acoustic Characterization of Gas Seepage at Yam Seep: Exploring the Influence of Methane Concentration on Sound Propagation

Gas seepage is a common geological phenomenon observed at continental margins. This study aim to monitor and quantify the optimal distance from the source for gas bubbles by conducting acoustic experiments at Yam Seep, located in the southwestern offshore region of Taiwan. This research utilizes a 3D parabolic model to determine the ideal positioning of the source and hydrophone in relation to gas flare locations, thereby investigating the impact of gas flares on sound propagation. Our objective is to address uncertainties in sound propagation resulting from gas emissions, which may aid in mitigating geohazards and improving the monitoring of ocean stability. Additionally, by quantifying the volume of gas emissions, we can gain a deeper understanding of the various geological processes that drive gas seepage, facilitating further exploration of the region's subsurface dynamics and contributing to the comprehension of gas-related geological risks.
