Great Artesian Basin Potentiometric Surfaces

These grids represent the potentiometric surface of the Cadna-owie - Hooray Aquifer in the Great Artesian Basin at 20 year intervals from 1900-2010. They were interpolated from GAB water table elevations and from observations of hydraulic head obtained from state groundwater databases. Head measurements were density corrected prior to creation of surfaces. Where there were no temperatures supplied with the head measurement to allow correction, temperature was interpolated from dataset 'Great Artesian Basin groundwater temperature' (Geoscience Australia dataset, Catalogue No. 76929, available from http://www.ga.gov.au).The grid surfaces 1900-1920, ?, 2000-2010 account for the possible effects of geological faults on groundwater flow in the GAB. Grids 1900-1920_nf and 2000-2010_nf are without the influence of regional tectonic faulting. Null values assigned as 1.000000e+30. Grid cell size (X, Y) = 5000 m, 5000 m. This GIS data set and metadata was produced by CSIRO for the Great Artesian Basin Water Resource Assessment and used in figures 7.2, 7.3 and 7.4 of Ransley TR and Smerdon BD (eds) (2012) Hydrostratigraphy, hydrogeology and system conceptualisation of the Great Artesian Basin.

Projection is Albers equal area conic, with central meridian 143 degrees longitude, standard parallels at -21 and -29 degrees latitude and latitude of projection's origin at -25.
