Gravity (400m) of WA v1, 2020 (DMIRS-070)

Bouguer Gravity - The data are displayed using a pseudo colour ramp with relief shading (azimuth 0°, elevation 80°). Values from low to high are represented by colours blue to red. This grid combines onshore Spherical Cap Bouguer gravity anomalies with offshore Free-air anomalies for Western Australia. Ground data over the continental region have been extracted from the Australian National Gravity Database (ANGD) and corrected for terrain effects. The ground data have been merged with 23 airborne vertical gravity and gravity gradiometer surveys acquired at various line spacings. Offshore Ellipsoidal Free-air gravity anomalies are based on gravity (V16.1) and topography (V9.1) data extracted from the Marine Gravity from Satellite Altimetry dataset (Sandwell and Smith, 1997, 2005).
