UKANET

SEISMIC NETWORK

SEISMIC NETWORK

The UKANET seismic network consisted of 10 stations distributed over the southern Antarctic Peninsula and Ellsworth Land. The Peninsula stations were located at, or close to, British Antarctic Survey bases, with some co-located with UKANET GNSS stations. The other seismic stations were in more remote locations. In collaboration with our US POLENET (Polar Earth Observing Network) partners, the westernmost stations formed a transect across Pine Island Glacier and several deep subglacial basins of the West Antarctic Rift System. Instruments were deployed between 2015/16 and 2017/18.

EQUIPMENT

Our equipment followed the POLENET setup, as advocated by IRIS PASSCAL (Incorporated Research Institutions for Seismology Program for Array Seismic Studies of the Continental Lithosphere) following a decade of polar deployments.

​

We used cold-rated 3-component Güralp 3TP broadband seismometers that have a flat response to ground velocity between 120 s and 100 Hz. The data were digitised and logged using a Quanterra Q330 and B44 baler combination. Stations were powered by solar energy  during the polar summer and lithium metal batteries during the polar winter. Xeos Iridium systems allowed us to remotely monitor the state of health of the stations.
