Great Artesian Basin aquifer groundwater chemistry grids

Brief description

Grids representing chemical parameter concentrations and isotopic variations in groundwater in the Great Artesian Basin for the following aquifers: Adori Sandstone; Cadna-owie - Hooray and equivalents; Hutton Sandstone and Winton-Mackunda Formation. (Note: Stable isotope carbon variations, Carbon-14 variation and Chlorine ratios produced for the Cadna-owie-Hooray and equivalents only) Hydrochemical parameters and isotopic variations mapped are: - Total dissolved solids (TDS) (mg/L) (adori_tds.txt, cad-hoor_tds.txt, hutton_tds.txt, wint-mack_tds.txt) - Total alkalinity (mg/L CaCO3) (adori_alk, cad-hoor_alk, hutton_alk, wint-mack_alk) - Sulphate (mg/L) ( adori_so4, cad-hoor_so4, hutton_so4, wint-mack_so4) - Fluoride (mg/L) ( adori_flu, cad-hoor_flu, hutton_flu, wint-mack_flu) - Sodium adsorption ratio (adori_sar, cad-hoor_sar, hutton_sar, wint-mack_sar) - Stable carbon isotope variations (d13C % PDB) ( tp-rs_13c_ch) - Carbon-14 variation (14C pMC) ( tp-rs_14c_ch) - Chlorine-36 to Chloride ratio ( t-rs_36clr_ch) Grid cell size (X, Y) = 0.015 DD, 0.015 DD. These GIS data sets were produced for the Great Artesian Basin Water Resource Assessment and used in Figures 8.2, 8.4, 8.5, 8.6, 8.8, 8.10, 8.12 and 8.13 of Ransley TR and Smerdon BD (eds) (2012) Hydrostratigraphy, hydrogeology and system conceptualisation of the Great Artesian Basin.

This dataset and associated metadata can be obtained from www.ga.gov.au, using catalogue number 76942.
