Summary

Abstract:
The aim of the seismic reflection and refraction measurements of the ARK-VII/3b expedition was to: a) map the crustal structure of totally different geological units in a region of close proximity, b) map the sedimentary distribution and the western boundary of the Mesozoic sediment basin of Jameson Land, c) map especially the Quaternary sediments to reconstruct the extension of the Quaternary glaciers and the different glacial phases. Shot interval was 25 m to 50 m for the reflection and 50 m to 75 m for the refraction seismic data. The data are in processing now with emphasis on velocity analysis and multiple suppression for the seismic reflection data. The following instruments were used: 100 and 800 m long streamer (24 channel), 6 and 32 l airgun array, 0.5 litres watergun, 32 l airgun. 6-channel Reftek stations, PCM stations with seismometers and geophone arrays. The geographical coverage is as follows: ARK-VIII/3b: 2440 km of multi-channel reflection seismic and 2440 km of refraction seismic data, and ARK-X/2: 1000 km of multi-channel reflection seismic and 1800 km of refraction seismic data, covering the whole of Scoresby Sund and adjacent fjords. Data are available on request, but with special arrangement |
