Transforming analogue sparker records from the Norwegian continental shelf into SEG-Y format - technical report, SPARDIG project.

Abstract

Analogue seismic lines (sparker) acquired mainly by IKU during 17 surveys in the period 1970-1984 have been transformed to SEG-Y format. The old data, which make up a regular seismic grid from 60\u00B0N (Northern North Sea) to ca. 71\u00B030'N (Tromsøflaket; SW Barents Sea), are of medium to good quality.A total of 31 261 km of sparker lines were processed and transformed. Compared to conventional seismic lines the resolution of sparker is better. An integrated interpretation of SEG-Y transformed sparker together with available 2D seismic data and high resolution bathymetric datasets will have a large potential for improved geological regional mapping of the upper layers of the seabed.
