MRTAS Offshore NW Tasmania magnetic grid geodetic
Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data 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 MRTAS Offshore NW Tasmania magnetic grid geodetic has a cell size of 0.00167 degrees (approximately 163m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 2008 by the TAS Government, and consisted of 43783 line-kilometres of data at 800m line spacing and 85m terrain clearance.

- Statement
-
This MRTAS Offshore NW Tasmania magnetic grid geodetic is an airborne-derived Total Magnetic Intensity (TMI) grid for the Offshore NW Tasmania, Tas, 2008 survey. The survey was acquired under the project No. 1181 for the geological survey of TAS. The grid has a cell size of 0.00167 degrees (approximately 163m). The units are in nanoTesla (or nT). A total of 43783 line-kilometres of data at a line spacing of 800m and 85m terrain clearance were acquired to produce this grid. Details of the specifications of individual airborne surveys can be found in the Fourteenth Edition of the Index of Airborne Geophysical Surveys (Percival, 2014). This Index is also available online at http://pid.geoscience.gov.au/dataset/79134.
