Data was obtained from 31-Aug-2021 to 10-Oct-2021. The experiment consists of 3x Geophone loggers deployed on landfast ice just north of Casey station.
Geophone loggers record vibrations using a tri-axis GS-ONE geophone. The tri-axis geophone was dug slightly in the top layer of the ice (few centimeters), and the hole was filled with a mixture of snow and fresh water to create a slush for rapid refreezing.
The geophone converts motion of a mass suspended by a spring to a voltage. The voltage is proportional to the velocity of the mass' motion. The GS-One has a (open-circuit) sensitivity of 85.8 V/m/s (+- 3.5%) and a corner frequency of 10Hz. Spurious frequency is 240 Hz. The geophone will still respond to vibrations of frequencies
