Summary Abstract: Soil samples were collected and analysed from three profiles across the Wright Valley, to determine the abundance of sodium, magnesium, calcium, potassium, chloride and some minor elements in the salts in soil. Samples were analysed for ionic abundance (mgm/cm2) and ionic ratios. In all, 123 samples were collected with a 2cm2 corer and 650 analyses were performed on 80 of these. The aim of this project was to be able to explain why there are drastic differences in water chemistry between the lakes in the the Taylor Valley and Wright Valley. It was hoped to be able to determine the mechanism for separating the sodium chloride from the calcium chloride or some mechanism for exchanging sodium for calcium.

Quality

In the University of Waikato Antarctic Research Unit Report (found in the Antarctica New Zealand logistic reports), some results are listed. For each traverse (Mt Jason - 22 samples, Mt Odin - 37 samples, Don Juan - 20 samples and water samples from Lake Vanda and Don Juan Pond were analysed) there reported data is altitude (feet), mean core length (cm), abundance mgm/cm2 of chloride, sodium, calcium, magnesium, potassium, lithium, rubidium and strontium, ionic ratios of Cl/Na, Ca/Na, Mg/Na, K/Na, Li/Na, Rb/Na and Sr/Na and ratios of abundance above and below upper lake levels of Chl and Na. Please contact the investigator for more information.
