    Sammanfattning : This doctoral dissertation presents a study of the glacial history of the North American Cordillera using numerical ice sheet modelling calibrated against field evidence. This area, characterized by the steep topography of several mountain ranges separated by large inter-montane depressions, was once covered by a large-scale ice mass: the former Cordilleran ice sheet.

  2. 2. Retreat pattern and dynamics of glaciers and ice sheets: reconstructions based on meltwater features

    Detta är en avhandling från Stockholm : Department of Physical Geography and Quaternary Geology, Stockholm University

    Författare :Martin Margold; Stockholms universitet.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Palaeoglaciology; Cordilleran Ice Sheet; deglaciation; glacial meltwater features; glacial lake; Physical Geography; naturgeografi;

    Sammanfattning : Glaciers and ice sheets covered extensive areas in the Northern Hemisphere during the last glacial period. Subsequently to the Last Glacial Maximum (LGM), they retreated rapidly and, except for Greenland and some other ice caps and glaciers, they vanished after the last glacial termination. LÄS MER

  3. 3. Retreat pattern and dynamics of glaciers and ice sheets: reconstructions based on meltwater features

    Detta är en avhandling från Stockholm University

    Författare :Martin Margold; Stockholms universitet.; [2010]
    Nyckelord :;

    Sammanfattning : The pattern of ice marginal retreat during the last deglaciation has, thus far, most frequently been reconstructed using absolute dating methods and landform record. In reconstructions using landform record, meltwater system has most often been neglected. This is predominantly a consequence of the smaller scale of meltwater features. LÄS MER
