Measurements of crystal size have been made on seven firn cores drilled at sites covering a range of mean annual temperature from -12.6 °C to -52.5 °C and a range of accumulation rate from 52 to 315 kg/sq.m/a. The sorting coefficient…
The temperature of upper 20 m was measured at four sites, S1, LJ, LJ24 and BJ, during a period of 21 months at the western Law Dome, Antarctica. the sensors were emplaced at the depths of 1, 2.5, 5, 7.5, 10, 15 and 20 m. S1 is in ablation sphere with a dynamo-metamorphosed ice…
The borehole BHQ, 430 m deep, was drilled in Law Dome, Antarctica, by the Australian National Antarctic Research Expedition in 1977. The core from BHQ was estimated to contain ice layers for about 5000 a, and was sent partly to China in 1983 for studies in detail.
Remote sensing techniques can be used to investigate the dynamics and surface characteristics of the Antarctic ice sheet and its outlet glaciers. This paper describes a methodology developed to map glacial movement velocities from LANDSAT MSS data…
