<div dir="ltr"><div>Dear Colleagues,</div><div><br></div><div>We would like to let you know about our session: "A117 - Sounds of the Solar System: Geophysical and Planetary Acoustics." We welcome submissions from all walks of geophysical acoustics, including propagation at thermospheric and ionospheric altitudes. Acoustics is emerging as an important line of investigation on other planets: abstracts focusing on these aspects are welcome as well. Session description follows.</div><div><br></div><div>Best,</div><div><br></div><div>Danny Bowman</div><div><br></div><div>Forces imposed on the atmosphere of Earth and other planets can create
acoustic waves that travel vast distances, providing information on
their source and the transmission medium. On Earth, low frequency sound
("infrasound") sensors can capture signals from natural sources
(volcanoes, earthquakes, severe storms, bolides, gravity-driven flows
etc.) and human activities (chemical and nuclear explosions, wind
turbines, dams, etc.). These sounds can be inverted to determine
atmospheric structure. They may also carry energy into the upper
atmosphere, creating localized heating. The recent detection of Martian
infrasound via the InSight lander has highlighted the scientific
dividends of acoustic monitoring on other solar system bodies as well.
In fact, studies of acoustic wave propagation have also been performed
for Venus, Jupiter, and Titan. This session is dedicated to
highlighting studies of acoustic waves on the Earth and beyond. We
invite theoretical, numerical, and experimental studies in geophysical
and planetary acoustics.</div></div>
