[MTT05-P04] Infrasound signal detected at the Lützow-Holm Bay region, East Antarctica, and their relation to surface environment
Keywords:Infrasound, Seismic waves, Antarctica, Microbaroms, icequake, Sensor array
Detailed and continuous measurements of infrasound waves in Antarctica could prove to be a new proxy for monitoring regional environmental change as well as temporal climate variations in high southern latitudes.
Until now, these arrays clearly detected the propagation direction and frequency content of microbaroms from the Southern Ocean. In addition to the microbaroms, several other remarkable infrasound signals were detected, including regional earthquakes, and so on.
In this presentation, we would introduce detected infrasound signals.
