  • Application of a two-step approach for mapping ice thickness to various glacier types on Svalbard 
    Jakob Fürst, Johannes; Gillet-Chaulet, Fabien; Benham, Toby; Dowdeswell, Julian A.; Grabiec, Mariusz; Navarro, Francisco; Pettersson, Rickard; Moholdt, Geir; Nuth, Christopher; Sass, Björn; Aas, Kjetil Schanke; Fettweis, Xavier; Lang, Charlotte; Seehaus, Thorsten; Braun, Matthias (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    The basal topography is largely unknown beneath most glaciers and ice caps, and many attempts have been made to estimate a thickness field from other more accessible information at the surface. Here, we present a two-step ...
  • Glacial, fluvial and contour-current-derived sedimentation along the northern North Sea margin through the Quaternary 
    Batchelor, Christine L.; Bellwald, Benjamin; Planke, Sverre; Ottesen, Dag; Henriksen, Sverre; Myklebust, Reidun; Johansen, Ståle E.; Dowdeswell, Julian A. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    The thick sequence of Quaternary sediments preserved within the northern North Sea contains important information about the glacial history, palaeo-oceanographic conditions and slope stability of this region during the ...
  • How accurate are estimates of glacier ice thickness? Results from ITMIX, the Ice Thickness Models Intercomparison eXperiment 
    Farinotti, Daniel; Brinkerhoff, Douglas J.; Clarke, Garry K.C.; Fürst, Johannes J.; Frey, Holger; Gantayat, Prateek; Gillet-Chaulet, Fabien; Girard, Claire; Huss, Matthias; Leclercq, Paul Willem; Linsbauer, Andreas; Machguth, Horst; Martin, Carlos; Maussion, Fabien; Morlighem, Mathieu; Mosbeux, Cyrille; Pandit, Ankur; Portmann, Andrea; Rabatel, Antoine; Ramsankaran, Raaj A.A.J.; Reerink, Thomas J.; Sanchez, Olivier; Stentoft, Peter A.; Singh Kumari, Sangita; van Pelt, Ward J.J.; Anderson, Brian; Benham, Toby; Binder, Daniel; Dowdeswell, Julian A.; Fischer, Andrea; Helfricht, Kay; Kutuzov, Stanislav; Lavrentiev, Ivan; McNabb, Robert Whitfield; Gudmundsson, G. Hilmar; Li, Huilin; Andreassen, Liss Marie (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Knowledge of the ice thickness distribution of glaciers and ice caps is an important prerequisite for many glaciological and hydrological investigations. A wealth of approaches has recently been presented for inferring ice ...
  • Progress toward globally complete frontal ablation estimates of marine-terminating glaciers 
    Kochtitzky, William; Copland, Luke; Van Wychen, Wesley; Hock, Regine; Rounce, David R.; Jiskoot, Hester; Scambos, Ted A.; Morlighem, Mathieu; King, Michalea; Cha, Leo; Gould, Luke; Merrill, Paige-Marie; Glazovsky, Andrey; Hugonnet, Romain; Strozzi, Tazio; Noël, Brice; Navarro, Francisco; Millan, Romain; Dowdeswell, Julian A.; Cook, Alison; Dalton, Abigail; Khan, Shfaqat; Jania, Jacek (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Abstract Knowledge of frontal ablation from marine-terminating glaciers (i.e., mass lost at the calving face) is critical for constraining glacier mass balance, improving projections of mass change, and identifying the ...
  • The unquantified mass loss of Northern Hemisphere marine-terminating glaciers from 2000–2020 
    Kochtitzky, William; Copland, Luke; Van Wychen, Wesley; Hugonnet, Romain; Hock, Regine; Dowdeswell, Julian A.; Benham, Toby; Strozzi, Tazio; Glazovsky, Andrey; Lavrentiev, Ivan; Rounce, David R.; Millan, Romain; Cook, Alison; Dalton, Abigail; Jiskoot, Hester; Cooley, Jade; Jania, Jacek; Navarro, Francisco (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Abstract In the Northern Hemisphere, ~1500 glaciers, accounting for 28% of glacierized area outside the Greenland Ice Sheet, terminate in the ocean. Glacier mass loss at their ice-ocean interface, known as frontal ablation, ...
