    The first aircraft-based observations of an Icelandic dust storm are presented. The measurements were carried out over the ocean near Iceland's south coast in February 2007. This dust event occurred in conjunction with an ...

    In recent years, water shortage is becoming one of the most serious problems in the Poyang Lake. In this paper, the long-term water balance items of the Poyang Lake have been analyzed to reveal the coupling effects of Three ...
  • Aslan, G; Cakir, Ziyadin; Ergintav, Semih; Lasserre, Cécile; Renard, Francois (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    The identification and measurement of ground deformations in urban areas is of great importance for determining the vulnerable parts of the cities that are prone to geohazards, which is a crucial element of both sustainable ...
  • Vestreng, Vigdis; Støren, Egil (Research report / Forskningsrapport, 2000)
  • Cornet, Jan Stanislas P. E. (Doctoral thesis / Doktoravhandling, 2018)
    Rock salt creeps under shear at the low temperatures encountered close to the surface. Salt flow is problematic for any cavity, like caverns or wells, because of the time dependent closure it induces if the internal hole ...
  • Nurullina, Rauza (Master thesis / Masteroppgave, 2006)
    The study area of this work belongs to continental margin offshore Angola. Despite the large amount of data acquired, the geometries of subsalt sedimentary layers and lower crustal structure offshore Angola remain much ...
  • Abate, Eyilachew Yitayew (Master thesis / Masteroppgave, 2010)
    Abstract This study describes the contribution of anthropogenic factors for groundwater pollution in the urban environment of developing countries. Dire Dawa is one of the oldest urbanized and densely populated city in ...
  • 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 ...
  • Debella-Gilo, Misganu (Master thesis / Masteroppgave, 2007)
    Digital terrain modeling has revolutionized the way topography is characterized and analyzed. Its applicability has widened to almost anything where topography has a role to play. On the other hand, digital soil mapping ...
  • Ashwal, Lewis D.; Wiedenbeck, Michael; Torsvik, Trond Helge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    A fragment of continental crust has been postulated to underlie the young plume-related lavas of the Indian Ocean island of Mauritius based on the recovery of Proterozoic zircons from basaltic beach sands. Here we document ...
  • Moore, JC; Rinke, A; Yu, X; Ji, D; Cui, X; Li, Y; Alterskjær, Kari; Kristjansson, Jon Egill; Muri, Helene; Boucher, O; Huneeus, N; Kravitz, B; Robock, A; Niemeier, U; Schulz, M; Tilmes, S; Watanabe, S; Yang, S (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
    We analyze simulated sea ice changes in eight different Earth System Models that have conducted experiment G1 of the Geoengineering Model Intercomparison Project (GeoMIP). The simulated response of balancing abrupt quadrupling ...
  • Prata, Alfredo; Dezitter, Fabien; Davies, Ian; Weber, Konradin; Birnfeld, Manfred; Moriano, David; Bernardo, Cirilo; Vogel, Andreas; Prata, Gemma S.; Mather, Tasmin A.; Thomas, Helen E.; Cammas, Jean; Weber, M. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    Airborne volcanic ash particles are a known hazard to aviation. Currently, there are no means available to detect ash in flight as the particles are too fine (radii < 30 μm) for on-board radar detection and, even in good ...
  • Luna, Byron Quan (Master thesis / Masteroppgave, 2007)
    In October 2005, massive slope failures were triggered all around Guatemala by the heavy rainfall that accompanied Hurricane Stan and unchained a series of landslides, debris flows and lahars. Two communities called Panabaj ...
  • Pulver, Kari-Anita R (Master thesis / Masteroppgave, 2006)
    Abstract: Accurate vegetation mapping is a crucial tool in the decision making process for the proper management of outfield areas. This thesis assesses the use of Landsat TM and ETM+ data for mapping the grazing quality ...
  • Miller, Charlotte Sarah; Peterse, Francien; da Silva, Anne-Christine; Baranyi, Viktoria; Reichart, Gert-Jan; Kürschner, Wolfram Michael (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    The geological record contains evidence for numerous pronounced perturbations in the global carbon cycle, some of which are associated with mass extinction. In the Carnian (Late Triassic), evidence from sedimentology and ...
