Wind-induced seismic noise at the Princess Elisabeth Antarctica Station [PDF]

open access: yesThe Cryosphere, 2021
Icequakes are the result of processes occurring within the ice mass or between the ice and its environment. Studying icequakes provides a unique view on ice dynamics, specifically on the basal conditions.
