• 3D seismic data indicate potential glide planes for submarine sliding : the mid-Norwegian margin Nyegga area. 

      Eilertsen, Håkon Andre (Master thesis; Mastergradsoppgave, 2010-05-15)
      The Nyegga study area of the thesis is located at the north-eastern escarpment of the Holocene giant Storegga Slide. It lies on the southern part of the Vøring plateau on the mid-Norwegian continental margin at approximately 700-1000m water depth. The area has been known to be prone for submarine sliding and is therefore an excellent location for studying morphological features to infer slide ...
    • 3D seismisk analyse av begravde rasavsetninger på den SV delen av Vøringmarginen 

      Johansen, Runar (Master thesis; Mastergradsoppgave, 2010-05-18)
      To 3D-seismiske datasett fra den sørvestlige delen av Vøringmarginen på midtnorsk kontinentalsokkel er blitt brukt til å analysere den øvre del av Naustformasjonen (~0,5-0,2 ma). En seismisk stratigrafi med fire hovedenheter er etablert (enhet 1-4). De to eldste enhetene (enhet 1 og 2) er dominert av glasiale debrisstrømmavsetninger dannet under glasiale maksima da det Fennoskandiske isdekket nådde ...

    • 3D seismisk analyse av storskala sandinduksjoner i Ormen Lange området i den midtnorske marginen 

      Holbæk-Hanssen, Leif Egil (Master thesis; Mastergradsoppgave, 2009-05-14)
      Analyser av 3D seismiske data fra Ormen Lange området på den midtnorske marginen har resultert i oppdagelsen av amplitudeanomalier som krysser diskordant opp gjennom, de sterkt polygonalt forkastede, biogene silikasedimentene i Bryggeformasjonen av Oligocen alder. Disse amplitudeanomaliene har en slående likhet med lignende amplitudeanomalier som er tolket til å være sandintrusjoner i Nordsjøen. ...

      The present work focuses on the onshore/offshore analysis and correlation of brittle faults and fractures on the Porsanger Peninsula area in west-Finnmark, the shelf areas and the immidiate offshore areas (Finnmark Platform and Gjesvær low). Structural field observation, microstructural and SEM analysis provide the basis for the characterization of the geometry, kinematics and fault rocks. This data ...
    • Atmospheric circulation patterns associated with avalanche cycles in the Troms region 

      Jenssen, Marius (Master thesis; Mastergradsoppgave, 2018-05-15)
      Snow avalanches endangers human lives and infrastructure situated in alpine environments during the winter season. Occurrence of avalanche activity is a product of processes taking place in the snow cover situated in steep terrain, which are governed by meteorological conditions induced by synoptic weather patterns. Avalanche forecasting can therefore better forecast avalanche activity if they ...
    • Bretilbaketrekningshistorie og landformer foran Steindalsbreen, Lyngen, Troms 

      Nilsen, Carina (Master thesis; Mastergradsoppgave, 2016-06-15)
      Steindalen er lokalisert sør på Lyngenhalvøya, i Troms fylke. Steindalsbreen er en av de lettest tilgjengelige breer i området. Dette gjør breen til et yndet turmål, men det gjør det også lettere å studere en bre på nært hold. Undersøkelse av Steindalsbreen har foregått ved hjelp av feltturer til området, ved å studere foto og flybilder over området og ved å sammenstille data samlet over mange år, ...

These are from bottom to top: part of the Kalak Nappe Complex (KNC), the Vaddas, the Kåfjord and the Nordmannvik nappe. In the present study the geology of these nappes is described, macroscopic and microscopic deformation structures are analyzed, and phase equilibrium modeling is ...
    • Carbonate concretions in an ice-contact delta, Skarmunken, Ullsfjord, northern Norway 

      Amundsen, Mats (Master thesis; Mastergradsoppgave, 2017-03-10)
      At Skarmunken, a small village south of Ullsfjord, northern Troms, Norway, an outcrop containing carbonate concretions have been investigated. From sedimentary logging, five facies (facies A-E) have been classified by their grading and composition. Depositional data from logs, maximum pebble size (MPS) and earlier investigations suggests an ice-contact delta. TOC/TS data have revealed a dominantly ...
    • The Cenozoic pre-glacial sedimentary environment of the SW Barents Sea continental margin – Lofoten Basin 

      Høgseth, Gert Vidar (Master thesis; Mastergradsoppgave, 2016-05-15)
      2D seismic data have been analysed to study the Cenozoic pre-glacial sedimentary environment on the southwest Barents Sea margin and the Lofoten Basin. Based on a seismic stratigraphic analysis and correlation to previous work in the area, the pre-glacial seismic unit G0 has been subdivided into four. The four units have been described and discussed with regards to the geometry and internal seismic ...
    • Characterisation of palaeosols in the Lower Cretaceous Helvetiafjellet Formation, Svalbard. Palaeo-climatic implications 

      Tennvassås, Ingrid (Master thesis; Mastergradsoppgave, 2018-05-15)
      Although the Cretaceous period is known to have been dominated by greenhouse conditions, the Early Cretaceous climatic conditions in Svalbard have been under some debate. Both indicators of warm climate such as coal seams, Ornithopod tracks and warm-water dinoflagellates, and indicators of cold climate such as arctic belemnites, glendonites and ice rafted debris have been reported. This study ...
    • Climate reconstruction during the Last Glacial Maximum based on a marine sediment core from Vestnesa Ridge, Svalbard 

      Matteis, Felix (Master thesis; Mastergradsoppgave, 2018-07-14)
      The sediment core HH15-1255PC has been analyzed to reconstruct the climate in the Fram Strait during the last 45,000 years. The coring site is located west of Svalbard on the Vestnesa Ridge, a contourite drift with a high-resolution sedimentary record (Plaza-Faverola et al., 2015). This ridge also includes a pockmark field formed by methane seepage (Vogt et al., 1994). The core HH15-1255PC is a ...
    • A combined 3D seismic and sedimentological study of the Lower Cretaceous succession in the northeastern part of the Nordkapp Basin 

      Brennhaugen, Adam Alfred (Master thesis; Mastergradsoppgave, 2018-05-15)
      In this master’s thesis in geology, 3D seismic data and shallow stratigraphic cores were used to investigate the Lower Cretaceous succession in the central sub-basin of the Nordkapp Basin, Barents Shelf. The Lower Cretaceous is listed as a potential petroleum play model on the Barents Shelf, which makes the succession of interest for petroleum exploration. Recent studies of the have divided the ...
    • Combining geophysical data with a mathematical model to describe vertical two-phase flow 

      Hansen, Johanne (Master thesis; Mastergradsoppgave, 2018-05-15)
      This thesis combines a geological model with a mathematical model to describe the vertical propagation of a gas plume through layers with different physical properties. The geological model is based on geophysical data from the Sørvestsnaget Basin and the mathematical model is derived based on the classical Buckley-Leverett theory for two-phase flow. The model estimates the velocity of a vertical ...
    • A comparative seismic study of gas chimney structures from active and dormant seepage sites offshore mid-Norway and west-Svalbard 

      Virs, Robert (Master thesis; Mastergradsoppgave, 2015-05-15)
      Understanding the fluid flow and the related fluid expulsion from gas chimneys and pipe structures is very important to our environment, since seeping methane has a great influence on our Earth’s climate. Chimneys are found in many places in the world, for instance at the Vestnesa ridge offshore western Svalbard and at the Nyegga region on the mid Norwegian margin. Plumbing systems and chimney ...
    • Comparison and classification of an Arctic Transitional snow climate in Tromsø, Norway 

      Velsand, Paul (Master thesis; Mastergradsoppgave, 2017-10-11)
      Winter tourism in Tromsø has increased significantly over the last years, consequently also the skiing tourism. It is advertised that Tromsø has a mild coastal climate compared to other destinations at similar latitudes. Existing snow climate classes separate covers into a maritime, continental and a transitional class where persistent weak layers are rare in the maritime class. Rain and average air ...
    • Comparison of 3D and 2D rockfall models. Considering terrain model quality effect on respective model performances 

      Hind, Håvard (Master thesis; Mastergradsoppgave, 2018-05-15)
      Rockfalls are blocks of rock that bounce and roll down slopes. They are commonly detached from rock-slopes with inclinations over 40-45°. They embody high energy and mobility and are a major cause of landslide related deaths. Rockfalls can be simulated using empirical relationships and modelling, of which 2D and 3D variants exist for the latter. 3D models allow for rock fragment- and surface shape ...
