Line Drawings of AGSO-Geoscience Australia's Regional Seismic Profiles, Offshore Northern and Northwestern Australia

Updated: 2026-07-23

Between 1990 and 1994, AGSO - Geoscience Australia acquired approximately 35,000km of regional, mostly deep (commonly 15s record length), 2D seismic reflection data along the northern and north-western continental margins of Australia. These data were shot primarily to provide a structural and tectonic framework to assist petroleum exploration companies in their search for hydrocarbons in the region, as well as an aid to understanding the margin's geological evolution. This CD contains line drawings of interpretations of all of the lines that compose the Geoscience Australia's regional grid. The interpretations (horizons and faults) were made by an external contractor to Geoscience Australia, IKODA Pty Ltd, using Landmark software, and build on previously published Geoscience Australia work of parts of the grid (e.g. papers in Purcell & Purcell, 1994) as well as tying to Geoscience Australia-sponsored detailed NW Shelf and Timor Sea high-resolution seismic studies.
