GSWA Yowalga Sub Basin total count grid geodetic

This GSWA Yowalga Sub Basin total count grid geodetic is an airborne-derived radiometric total count window countrate grid for the Yowalga Sub-Basin, WA, 1995-1996 survey. The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of total count (K), total count (U) and total count (Th). 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 GSWA Yowalga Sub Basin total count grid geodetic has a cell size of 0.001 degrees (approximately 105m). The data are in units of counts per second (cps). The data used to produce this grid was acquired in 1995 by the WA Government, and consisted of 87401 line-kilometres of data at 500m line spacing and 80m terrain clearance.

Statement

This GSWA Yowalga Sub Basin total count grid geodetic is an airborne-derived radiometric total count window countrate grid for the Yowalga Sub-Basin, WA, 1995-1996 survey. The survey was acquired in 1995 under the project No. 916 for the geological survey of WA. The data consisted of 87401 line-kilometres of data at 500m line spacing and 80m terrain clearance. The radiometric count rate is contaminated by background radiation contributions from the aircraft, cosmic rays, and the presence of Radon gas escaping from the ground. It is also affected by the ground clearance of the detector, as well as the volume of the detector. This grid was produced after applying radiometric corrections to the total count window data from the survey. Noise-adjusted singular value decomposition (NASVD) has been applied to the data. NASVD is a spectral component analysis procedure for the removal of noise from gamma-ray spectra. The final grid is checked for quality by GA geophysicists to ensure that the final data released are fit-for-purpose. This GSWA Yowalga Sub Basin total count grid geodetic has a cell size of 0.001 degrees (approximately 105m) and shows the total count window countrate of the Yowalga Sub-Basin, WA, 1995-1996 survey in units of counts per second (or cps). 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.
