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 document2) Shapefiles of the magnetic and gravity line data from the OBSP survey3) ASCII xyz grids of the OBSP and merged grids with public domain data4) Georeferenced (GeoTIFF) images of the survey and merged grids5) Gravity and Magnetic data processing reports from the OBSP survey
