    Calibrated ice thickness estimate for all glaciers in Austria

    Helfricht, Kay ; Huss, Matthias ; Fischer, Andrea ; Otto, Jan-Christoph

    In: Frontiers in Earth Science, 2019, vol. 7, p. -

    Knowledge on ice thickness distribution and total ice volume is a prerequisite for computing future glacier change for both glaciological and hydrological applications. Various ice thickness estimation methods have been developed but regional differences in fundamental model parameters are substantial. Parameters calibrated with measured data at specific points in time and space can vary when...

    Investigating cold based summit glaciers through direct access to the glacier base: a case study constraining the maximum age of Chli Titlis glacier, Switzerland

    Bohleber, Pascal ; Hoffmann, Helene ; Kerch, Johanna ; Sold, Leo ; Fischer, Andrea

    In: The Cryosphere, 2018, vol. 12, no. 1, p. 401–412

    Cold glaciers at the highest locations of the European Alps have been investigated by drilling ice cores to retrieve their stratigraphic climate records. Findings like the Oetztal ice man have demonstrated that small ice bodies at summit locations of comparatively lower altitudes may also contain old ice if locally frozen to the underlying bedrock. In this case, constraining the maximum age...
