Seismic reflection data from a 50km line southeast of the summit of Mt Erebus to assess the amplitude and wavelength of crustal flexure associated with the load of the Ross Archipelago
Entry ID: K101_1988_1989_NZ_1

Abstract: A joint project between the New Zealand Geophysic Division (now IGNS), Stanford University and the University of Nebraska was conducted to carry out a seismic reflection line of approximate 50 km in length, southeast of Ross Island to assess the amplitude and wavelength of crustal flexure associated with the load of the Ross Archipelago. 50 km of 6-fold multichannel seismic reflections on a line that started approximately 60km southeast of the summit of Mt Erebus was completed. 5 kg dynamite charges were detonated in 20 m deep holes at intervals of 200 m along the full length of the line. A 30 km long wide-angle reflection/refraction experiment was also carried out to provide seismic velocity control throughout the crust. Deep reflections from the base of the crust were also recorded.
