gskyNONENONEapplication/vnd.ogc.se_xmlGravity data measure small changes in gravity due to changes in the density of rocks beneath the Earth\'s surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
This Australia gravity grid 2016 (complete spherical cap Bouguer anomaly) is a complete spherical cap Bouguer anomaly grid for the National Gravity Grids, 2016. This gravity survey was acquired under the project No. 4107 for the geological survey of None. The grid has a cell size of 0.00833 degrees (approximately 878m). The data are given in units of um/s^2, also known as \'gravity units\', or gu. A total of None gravity stations were acquired to produce this grid.

Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock.The first vertical derivative (1VD) grid is derived from the 2019 Total magnetic Intensity (TMI) grid of Australia which has a grid cell size of ~3 seconds of arc (approximately 80 m). As the vertical derivative filter is essentially a high-pass filter, longer wavelengths are suppressed, and shorter wavelengths emphasized. The magnetic units of the data are in nT per metre.

This grid only includes airborne-derived TMI data for onshore and near-offshore continental areas.Since the sixth edition was released in 2015, data from 234 new surveys have been added to the database, acquired mainly by the State and Territory Geological Surveys. The new grid was derived from a re-levelling of the national magnetic grid database. The survey grids were levelled to each other, and to the Australia Wide Airborne Geophysical Survey (AWAGS), which serves as a baseline to constrain long wavelengths in the final grid. It is estimated that 33 500 000 line-kilometres of survey data were acquired to produce the 2019 grid data, about 2 000 000 line-kilometres more than for the previous edition.
