Brief description

Gravity data measures 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 Sheffield Area North West Tasmania Gravity (P196850) contains a total of 856 point data values acquired at a spacing between 1000 and 2500 metres. The data is located in TAS and were acquired in 1968, under project No. 196850 for University of Tasmania.
