Active Seismics on Sorsdal Glacier 2016-2017
Listed in NASA Earthdata CMR
The active seismics are all part of a survey of the Sorsdal Glacier.
Description
They are designed to measure ice thickness, and the thickness of the water column underneath the ice shelf where the ice is floating. This was part of an investigation to determine the location of the grounding line on Sorsdal Glacier.
Active seismics on Sorsdal Glacier 2016-2017 using hammer and plate source method Sites visited: S02, S04, S06, S08, S11, Channel Lake Files included: *.dat - raw data files each containing seismic record from single shot *.xlsx - record of acquisition layout and settings, including notes for each shot Schaap_Thesis.pdf - Honours thesis from Tom Schaap, UTAS containing more informtaion on data e.g. Figure 3.1 - map of locations, Figure 3.2 - Diagram of geophone layout and shot locations for each site csv file with measured ice thickness and water column thickness is attached here.
