Ground to Space Geoacoustic Characterization during the DAG Experiment

Bowman, Daniel B.; Cutts, James; Komjathy, Attila; Pauken, Michael; Whitaker, Rod

It is therefore of paramount importance to quantify the three dimensional propagation characteristics of infrasound from buried sources. Despite initial success with using an octocopter to quantify ground motion with a seismic hammer (Jones et al., 2015), attempts to capture buried explosion sources using this method have proven very difficult. Even when successful, octocopter-borne sensors suffer from high levels of background noise, have limited flight time due to battery life, and require substantial resources to deploy.

Geoacoustics Takes to the Sky

Bowman, Daniel B.; Young, Eliot; Cutts, James

Low frequency sound waves transmit information on both natural and anthropogenic phenomena, transfer energy between the lower and upper atmosphere, and often propagate for thousands of kilometers. These sound waves are typically in the "infrasound" (below human hearing) range. Although the vast majority of geoacoustic sensor networks have existed on the Earth's surface, microphones drifting in the atmosphere may have much greater sensitivity as well as sample regions inaccessible from the ground.
