  • Wave-induced Lagrangian drift in a porous seabed 
    Weber, Jan Erik H.; Ghaffari, Peygham (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Abstract The mean drift in a porous seabed caused by long surface waves in the overlying fluid is investigated theoretically. We use a Lagrangian formulation for the fluid and the porous bed. For the wave field we assume ...
  • The wavelength selectivity of light scattering in the Barents Sea

  • Wazzani Spring : assessment of the present international water conflict between Lebanon and Israel - seen within an Arab-Israeli context. 
    Hansen, Anders Omberg (Master thesis / Hovedoppgave, 2005)
    The situation in the Middle East has over the last centuries received much attention from the international community. There is a long history of disputes over natural resources like oil and land in the Middle East, and ...
  • Weather routing : Sensitivity to ensemble wind and current input. 
    Kristensen, Nils Melsom (Master thesis / Masteroppgave, 2010)
    We consider the relative importance of wind and currents in the determination of optimal routes, commonly referred to as weather routing, for sailboats. Weather routing for sailboats is the process of finding the fastest ...
  • Weathering of Precambrian basement and formation of sedimentary particles in Scania

    Saprock-saprolite associations were studied by field and laboratory methods (optical microscopy, X-ray powder diffraction, scanning electron microscopy, electron microprobe) in order to describe regolith development in the ...
  • Weathering trends and secondary clay-mineral formation in monzogranites from Georgia, USA 
    Stangvik, Kristian Bendiksen (Master thesis / Masteroppgave, 2015)
  • Weekly glacier flow estimation from dense satellite time series using adapted optical flow technology 
    Altena, Bas; Kääb, Andreas (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Contemporary optical remote sensing satellites or constellations of satellites can acquire imagery at sub-weekly or even daily timescales. These systems have the potential to facilitate intra-seasonal, short-term surface ...
  • West Spitsbergen fold and thrust belt: A digital educational data package for teaching structural geology 
    Horota, Rafael Kenji; Senger, Kim; Rodes, Nil; Betlem, Peter; Smyrak-Sikora, Aleksandra; Jonassen, Marius Opsanger; Kramer, Daniel; Braathen, Alvar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    The discipline of structural geology is taking an advantage of compiling observations from multiple field sites to comprehend the bigger picture and constrain the region's geological evolution. In this study we demonstrate ...
  • What drives 20th century polar motion? 
    Adhikari, Surendra; Caron, Lambert; Steinberger, Bernhard; Reager, John T.; Kjeldsen, Kristian K.; Marzeion, Ben; Larour, Eric; Ivins, Erik R. (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
  • What explains inconsistencies in field-based ecosystem mapping? 
    Naas, Adam Eindride; Halvorsen, Rune; Horvath, Peter; Wollan, Anders Kvalvåg; Bratli, Harald; Brynildsrud, Katrine Marie; Finne, Eirik Aasmo; Keetz, Lasse Torben; Lieungh, Eva; Olson, Christine; Simensen, Trond; Skarpaas, Olav; Tandstad, Hilde; Torma, Michal; Værland, Espen Sommer; Bryn, Anders (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Questions: Field-based ecosystem mapping is prone to observer bias, typically resulting in a mismatch between maps made by different mappers, that is, inconsistency. Experimental studies testing the influence of site, ...
  • What is fieldwork for? Exploring Roles of Fieldwork in Higher Education Earth Science 
    Malm, Rie Hjørnegaard (Doctoral thesis / Doktoravhandling, 2021)
    This thesis provides insights into fieldwork practices in Higher Education Earth Science and how these practices influence students’ senses of belonging and their negotiations of geoscience identities. The work illustrates ...
  • What is the global glacier ice volume outside the ice sheets? 
    Hock, Regine; Maussion, Fabien; Marzeion, Benjamin; Nowicki, Sophie (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Abstract A recent study (Millan and others, 2022 a , Nature Geoscience 15(2), 124–129) claims that ice volume contained in all glaciers outside the ice sheets and its potential contribution to sea level is 20% less than ...
  • Which glaciers are the largest in the world? 
    Windnagel, Ann; Hock, Regine; Maussion, Fabien; Paul, Frank; Rastner, Philipp; Raup, Bruce; Zemp, Michael (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
