  2. 2. HOW WARM IS THE SOUTH POLE?
    Prof. Pavel G. Talalay (Jilin University)

    The Antarctic geothermal heat flux (GHF) has significant influence on the viscosity of basal ice and meltwater content at the ice–base interface. To evaluate GHF under the Antarctic Ice Sheet at South Pole, we used available temperature profile taken by AMANDA and IceCube thermistors installed at depths from 800 m to 2445 m in boreholes produced with hot-water drilling. We applied...

  3. 15. Ice-dynamic implications of geophysical studies upstream of South Pole

    The South Pole is at least 180 km from an ice-flow divide. Thus, the annual-equivalent layer thicknesses in the area are affected by spatial variations in accumulation upstream in addition to temporal variations in regional accumulation. We use a new method to compare the accumulation record from the South Pole Ice Core (SPICEcore), derived by correcting measured layer thicknesses for...

  4. 22. BedMachine: mapping the bed under the Antarctic ice sheet by combining sparse radar data and mass conservation
    Mathieu Morlighem (University of California)
    19/01/2021, 17:05

    Despite major advances in subglacial bed topography mapping over the past decades using nadir-looking radar sounding profiles, significant sectors remain poorly known and critical spatial details are missing, especially in the proximity of grounding lines. We present a novel, high-resolution, physical description of Antarctic bed topography and ice thickness that uses a mass conservation...

  5. 26. Analysis of Surface Motion with South Pole Campus
    George Blaisdell (Cold Regions Research and Engineering Laboratory)
    19/01/2021, 17:25

    Given the vast distance to bedrock and to the nearest outcrop, it seems justified to assume that the ice shelf flow regime at South Pole is uniform within the footprint of the Station. However, survey suggest otherwise.
