  • Basal conditions at Engabreen, Norway, inferred from surface measurements and inverse modelling 
    Solgaard, Anne; Messerli, Alexandra; Schellenberger, Thomas; Hvidberg, Christine; Grinsted, Aslak; Jackson, Miriam; Zwinger, Thomas; Karlsson, Nanna B; Dahl-Jensen, Dorthe (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Engabreen is an outlet glacier of the Svartisen Ice Cap located in Northern Norway. It is a unique glacier due to the Svartisen Subglacial Laboratory which allows direct access to the glacier bed. In this study, we combine ...
  • Interannual variability of glacier basal pressure from a 20 year record 
    Lefeuvre, Pierre-Marie; Jackson, Miriam; Lappegard, Gaute; Hagen, Jon Ove (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Basal pressure has been recorded at the Svartisen Subglacial Laboratory, northern Norway, for 20 years, and is measured by load cells installed at the ice–rock interface under ∼200 m of glacier ice. Synchronous pressure ...
  • Stress Redistribution Explains Anti-correlated Subglacial Pressure Variations 
    Lefeuvre, Pierre-Marie; Zwinger, Thomas; Jackson, Miriam; Gagliardini, Olivier; Lappegard, Gaute; Hagen, Jon Ove (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    We used a finite element model to interpret anti-correlated pressure variations at the base of a glacier to demonstrate the importance of stress redistribution in the basal ice. We first investigated two pairs of load cells ...
