Outline of Final Research Achievements

We have maintained broadband seismograph station in Greenland to define the fine structure and detailed mechanisms of glacial earthquakes within the Greenland Ice Sheet. We have started to operate ICESG station since 2011. We have visited the station every summer and successfully retrieved one year of continuous records from the broadband seismometer. The observed three component seismograms demonstrate that the quality of this ice sheet station is good enough to record not only local earthquakes around Greeland but also teleseismic earthquakes. We use 4.5-year ambient noise surface wave data from seismic stations all over Greenland to detect both seasonal and long-term changes in seismic velocity beneath the inter-station transect lines. We find a clear summer/long-term velocity decrease beneath a line in the north-central inland of the ice sheet, which is considered as an increase of meltwater due to ice sheet pressure melting.
