The heat balance and chemistry of Lake Bonney was investigated in the 1962-63 field season. Temperature profiles were measured through 11 holes drilled in the surface ice of Lake Bonney. Of these, ...


6. Investigation of the physics (heat balance) and chemistry of Lake Vanda, Wright Valley, 1961-1962 [K042_1961_1962_NZ_1]
The first study of the physics and chemistry of Lake Vanda and the geology of the surrounding area were investigated in the 1961-1962 field season. Twelve holes were drilled at 1000ft intervals along ...


7. Measurements of water temperature, spectral irradiance (amount of sunlight), density and salt concentration from lakes in the Taylor and Wright Valley [K042_1963_1964_NZ_1]
The physics and chemistry of the many lakes and ponds in the McMurdo Dry Valleys was investigated in the 1963-64 field season. Previous work on Lakes Vanda and Bonney in the Wright and Taylor Valleys ...


8. Water chemistry and biology of the Canada Glacier glacial meltwater stream [K009_1981_1982_NZ_1]
Lake water chemistry is relatively well understood, whereas in comparison stream waters have been little studied. The chemistry of glacial meltwater from the Canada Glacier was characterised and the ...


9. Chemical and nutrient analysis of meltwaters in the Victoria Valley and Bull Pass [K091_1989_1990_NZ_1]
Baseline chemistry data for ponds and lakes in the Victoria Valley/Bull Pass region was collected in January 1990. Water samples were taken from Upper Victoria Glacier drainage, Lake Victoria, Lake ...


10. Trace element distribution and speciation in Lake Vanda, Wright Valley, Antarctica [K093_1987_1988_NZ_1]
In Nov/Dec 1987, waters were sampled from Lake Vanda, Don Juan Pond, and the Onyx River (Wright Valley) to provide information on major ion and trace element chemistry and behaviour under the range ...


11. Analysis of water and soil samples for pollutants (trace metals, major anions, mercury) to determine the nature and extent of contamination in meltwaters in the Ross Dependency [K105_1992_1994_NZ_1]
A set of baseline data for the composition of meltwaters in the Ross Dependency, with particular concentrations on the levels of ultra trace heavy metals in waters remote from significant or current ...


12. Heavy metal analysis of soil samples from pits excavated around Scott Base [K105_1993_1994_NZ_1]
Comparison of soils from Scott Base (site with human activity) with baseline data taken from pristine sites around the Ross Dependency (without human activity) found elevated levels of most heavy ...


13. Salt, nutrient and other contaminant analysis of soil samples taken near the old Vanda Station [K105_1993_1994_NZ_2]
Water and soil samples from Vanda Station were found to have contamination by apparently anthropogenically derived components (such as heavy metals) and these contaminants are moving in the soils ...


14. Soil and salt samples and geological observations from high altitude sites in the Upper Taylor Valley to determine the history of the Antarctic environment through the composition of salts in soils [K105_1997_1998_NZ_1]
To understand the processes of Antarctic soils as they affect the composition and distributions of salts and ice in and below the soils, the salts in very old soils and paleosols were investigated. ...
