Major ion chemistry of Antarctic Saline Lakes

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
