Seismic campaigns in David Glacier (Expedition XXXI)

Seismological observations can be useful in the monitoring of ice stream dynamics and evolution. A temporary seismic array was deployed around the David Glacier, Victoria Land, during the austral summers 2015-16. Target of the experiment is the collection of seismometric data in order (i) to contribute to filling the gap in global seismic instrumentation, (ii) to monitor the Antarctic seismicity despite its weakness, (iii) to study the lithospheric and deep structure of the continent, (iv) to study interconnections between geodynamics and icecap and glacial evolution.
