Abstract

Abstract

There were two parts to the K045 scientific programme. The first involved the downhole velocity logging of the CIROS-1 drillhole at the completion of drilling. This work encountered severe noise problems which may make the signal irrecoverable. The second part of the event involved the determination, using seismic reflection techniques, of the dip, faults and strong reflectors in the geologic structure in the immediate vicinity of the CIROS-1 drillhole as well as the testing of various seismic reflection techniques for any future reflection projects on the sea-ice. Despite transport and manning problems 2 seismic lines were shot running at right angles from the CIROS-1 drillhole and records appear to have primary reflected energy down at least to 800 metres sub-seafloor. Tests proved explosives a more useful sound source than marine airguns.
