Transforming analogue sparker records from the Norwegian continental shelf into SEG-Y format - technical report, SPARDIG project.
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°N (Northern North Sea) to ca. 71°30'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.
