5 samples have either one estimated parameter or an incomplete data set. Major ion data for 41 samples from 10 lakes in the Vestfold Hills. Lakes: Cemetery, Club, Deep, Dingle, Jabs, Laternula, Lebed', Oblong, Organic and Stinear Parameters (measured and calculated): - Major anions and cations Total halides (mol/kg) by potentio titrn Cl (chlorinity (unitless, g/kg) calculated by Jacobsen and Knudsen formula Cl (mol/kg and g/kg) calculated by difference Br (mmol/kg and g/kg) from titration SO4 (mmol/kg and g/kg) from gravimetry total alkalinity (mmol or meq/kg and g/kg as HCO3) Ca (mmol/kg and g/kg) by photo titrn Mg+Sr (mmol/kg) by photo titrn M(II) (mmol/kg) calculated by summation of photo titrn data * Note: M(II) = total alkaline earths (Mg+Ca+Sr) Mg (mmol/kg and g/kg) calculated by difference Sr (mmol/kg and mg/kg) by flame-AAS Na (mol/kg and g/kg) by flame-AES K (mol/kg and g/kg) by flame-AES M(II) (mmol/kg) by potentio titrn (more accurate than photo titrn data) Mg (mmol/kg, g/kg) by difference (more accurate than data derived from photo titrn) - density of brine at 20 degrees C (g/cm3) * calculated values of relative density (relative to water) at 20 degrees C, and specific gravity - ion balance error (%) * calculated from selected mol/kg data for anions and cations - absolute salinity (g/kg) * calculated from selected g/kg data for anions and cations - empirical composition-chlorinity relations for VH brines - empirical and theoretical density-chlorinity or density-salinity relations * density expressed as relative density; vs chlorinity or absolute salinity; linear, quadratic, Root, Redlich * density expressed as specific gravity; vs chlorinity or absolute salinity; linear, quadratic - residual sulphate concentrations form composition analysis of brines - composition functions for VH brines * 'freezing' and 'gypsum' functions
