  2. 1. Past dynamics of a marine-terminating glacier in lower Borgarfjörður, west Iceland - Analyses of glaciotectonic sediments and landforms

    Author : Thorbjorg Sigfusdottir; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; glacier dynamics; marine-terminating glacier; glaciomarine processes; thrust-block moraines; glaciotectonics; micromorphology; Early Holocene; Late Weichselian; Iceland;

    Abstract : Large and complete sections through glacial landforms formed in subaqueous environments are rare, impeding our knowledge of their internal composition and the processes responsible for their formation. Following the last deglaciation of the Icelandic Ice Sheet (IIS), a marine-terminating outlet glacier advanced out of the fjord of Borgarfjörður resulting in large-scale glaciotectonic deformation of glaciomarine sediments.

  4. 2. Glacier-Ocean Interactions in the Arctic : Contemporary calving and frontal melt from field observations, remote sensing, and numerical modelling

    Author : Felicity Alice Holmes; Nina Kirchner; Benedict T. I. Reinardy; Riko Noormets; Jason Briner; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Glacier-ocean interactions; Arctic; Calving; naturgeografi; Physical Geography;

    Abstract : Globally, glaciers are losing mass as a result of the changing climate, with this mass loss having a considerable societal impact through rising sea levels. Glaciers which terminate in the oceans are particularly vulnerable to changing external conditions as a result of high sensitivity at their marine margins. READ MORE

  5. 3. Modelling calving and sliding of Svalbard outlet glaciers : Spatio-temporal changes and interactions

    Abstract : Future sea level rise associated to global warming is one of the greatest societal and environmental challenges of tomorrow. A large part of the contribution comes from glaciers and ice sheets discharging ice and meltwater into the ocean and the recent worldwide increase is worrying. READ MORE
