The UAF infrasound array in Antarctica provides a unique opportunity to study the propagation of sound in snow and the infrasound signals produced by the movement of snow. After a brief introduction to infrasound and a demonstration of instruments used to detect infrasound, I will describe our deployment of those instruments in Antarctica and show a few of the interesting and often mysterious signals that likely originate with sources such as snow avalanches, the settling of snow (aka firnstoss), and the atmosphere..
