Gravity and magnetic enhancement grids and images for the Otway Basin Seismic Program 2020
In association with the OB2020 seismic survey, over 8,200 line kilometre of gravity and magnetic data were acquired. These data were subsequently merged with existing satellite data to produce merged grids at 1000m grid cell size.
Several enhancement processing techniques were applied to these magnetic and gravity data to better highlight buried features within the Otway Basin. The merged input data from the survey and the enhanced products in this release provide valuable information on the geometry and spatial extent of igneous rocks in the deep-water basin. The distribution of these rocks is critical to the understanding of the petroleum systems and therefore the hydrocarbon prospectivity of the area.
This data package contains:
1) A metadata statement document
2) Shapefiles of the magnetic and gravity line data from the OBSP survey
3) ASCII xyz grids of the OBSP and merged grids with public domain data
4) Georeferenced (GeoTIFF) images of the survey and merged grids
5) Gravity and Magnetic data processing reports from the OBSP survey

- Purpose
-
The purpose of this data package is to provide enhanced grids and images of gravity and magnetic data acquired during the Otway Basin Seismic Program and merged with public domain satellite data. These images could be combined with other data for the interpretation of basement and shallow structures, including igneous rocks useful for basin prospectivity studies.

- Statement
-
New magnetic data from the Otway Basin Seismic Program (OBSP) were merged with public domain survey data to produce seamless magnetic maps of the combined onshore and offshore parts of the Otway Basin. Similarly, the new gravity data were merged with public domain satellite data to produce gravity images. Both the magnetic and gravity data were filtered and enhanced to better highlight some buried features in the basin. The data from the OBSP survey are available for download with the survey and processing reports from the National Offshore Petroleum Information System (www.nopims.gov.au) under ENO0603786.
