Between 1989/90 and 1994/95, geodetic GPS surveying techniques were used to measure ice sheet surface velocities at approximately 30 km intervals around an oversnow traverse route in the interior drainage basin of the Lambert Glacier, East Antarctica (longitude 54°-78°E, latitude 67°-76°S).
A new Holocene sea-level record from the Vestfold Hills, Antarctica, has been obtained by dating the lacustrine-marine and marine-lacustrine transitions that occur in sediment cores from lakes which were formerly connected to the sea. From an elevation of similar to 7.5 m 8000 years ago…
A method has been developed for the routine determination of four arsenic species (arsenite, arsenate, monomethylarsenic and dimethylarsenic) in natural water, and has been applied to a study of arsenic cycling in open ocean (Atlantic and Southern Ocean) and estuarine (Huon Estuary, Tasmania)…
Layered orthogneisses of the Oygarden Islands preserve evidence for four high-grade deformation events (D1 to D4). Archaean D1 and D2 structures are only patchily preserved due to extensive recrystallization during D3 and D4, which represent effects of the c.1000 Ma Rayner Structural Episode (RSE).
Surveys of ice thickness, surface elevation, velocity, and accumulation rate were made on the upper part of Totten Glacier by oversnow traverse during 1987.
There is a distinct directional anisotropy in microwave backscatter from the surface of the East Antarctic ice sheet as measured by the C-band wind scatterometer carried by the ERS-1 satellite.
Heard Island is a volcanic island, which is 80% ice-covered, situated in the southern Indian Ocean. Measurement of the variation in the mass and length of Heard Islands glaciers over time provides valuable data related to climatic change in a region mostly devoid of such information.
Deuterium excess (d = dD - 8 * d18O) values in surface snow are presented for central and east Antarctica. The samples are primarily from Soviet, French, and Australian traverses. The d values exhibit a large change going from coastal sites to high-altitude sites on the ice sheet.
Glaciology surveys of the ice sheet in Wilkes Land, Antarctica, have been made on oversnow traverses operating out of Casey. Data collected includes surface elevation, accumulation rate, snow temperature and physical characteristics of the snow cover.
