8. Examination of permafrost properties from soil samples and core samples from a range of disturbed soil surfaces sites at Marble Point and Scott Base/McMurdo Station [K150_1989_1990_NZ_1]
The properties of the permafrost immediately beneath the soil was investigated in a range of surfaces disturbed by earlier construction activities such as compacted fill, cut, embankment, retreated ...


9. Examination of the chemistry, physics and sedimentology of Lake Wilson, Waikato Valley, Brown Hills Region [K009_1974_1975_NZ_1]   PARENT DIF
Lake Wilson was examined to see if it contained permanent water. The thickness of the ice was described. 36 holes were drilled and the bathymetry was mapped. Surface sediment samples were collected ...


10. Geochemical and geochronology of late quaternary glaciations in the McMurdo Sound Region [K009_1982_1983_NZ_1]   PARENT DIF
The history and mechanics of the late Wisconsin age lakes which have periodically filled many of the lower portions of many of the Valleys that open into McMurdo Sound was studied from samples taken ...


11. Geological and geomorphic data and Sirius Group core analysis (stratigraphy, petrographical analysis, ground temperature and isotope analysis) from Table Mountain to determine the depositional history [K047_1996_1997_NZ_1]
The depositional and post depositional history of the Sirius Group tillite in the Dry Valleys area was investigated to resolve the ongoing debate as to whether the East Antarctic ice sheet formed ...


12. Gravimetric water contents of soils and permafrost from sites near Lake Vanda in the Wright Valley and at Beacon Heights in the upper Taylor Valley [K150_1993_1994_NZ_2]
The water content of soils and permafrost from localities with a climate contrasting to that of Scott Base were measured from sites near Lake Vanda in the Wright Valley and at Beacon Heights in the ...


13. Ice core and soft sediment samples from Lake Fryxell, Lake Vanda, Don Juan Pond and surrounding shallow lakes in the Wright Valley [K009_1978_1979_NZ_3]   PARENT DIF
A bathymetric map of Lake Fryxell was completed by drilling 28 holes through the floating ice and mapping the lake bottom. 13 cores were collected. The lake benthic sediment was cored for investigation. ...


14. Measurements of the effects of debris on the mechanical behaviour (deformation and motion) of ice of the Taylor Glacier, Taylor Valley, Antarctica [K053_1992_2000_NZ_1]
Debris-rich ice is a commonly observed basal ice facies found at the base of many temperate and polar glaciers and at the base of cores through major ice sheets. The effects of the presence of debris ...


15. Measurements of water loss from permafrost (soil ice/moisture content) in an experimentally disturbed and undisturbed permafrost area near Scott Base [K150_1993_1994_NZ_1]
Water content measurements were made continuously from 15 bore holes at an experimentally disturbed and undisturbed site at Scott Base to measure the amount of water loss from permafrost, to compare ...


16. Sediment cores from Lakes Fryxell, Lake Bonney and Lake Joyce, in the McMurdo Dry Valleys, Antarctica [K022_2002_2003_NZ_1]   PARENT DIF
