    • Salt movements in three provinces in the southwestern Barents Sea: development, timing, and implications of regional structural differences 

      Thorsen, Truls (Master thesis; Mastergradsoppgave, 2019-05-15)
      This study has investigated salt movements in the Nordkapp Basin, on the Loppa High (Svalis Dome) and on the Bjarmeland Platform (Samson- and Norvarg domes). The aim is to discuss how differences in salt growth potentially relates to the structural evolution of - and differences between - these three provinces. Evaluation of seismic 2D- and 3D data together with well correlation, allowed a regional ...

    • Sammenhengen mellom landskap og tektonikk på Moskenesøya og Flakstadøya, Lofoten. 

      Trulssen, Mads Fremming (Master thesis; Mastergradsoppgave, 2008-12-04)
      Lofoten utgjør en opphevet horst i forhold til omkringliggende bassenger og består hovedsakelig av prekambrisk grunnfjell. Tidligere modeller viser at landområdene og sokkelområdene utenfor Lofoten ser ut til å ha hatt en lik ekstensjonshistorie med flere faser av forkastningsbevegelser, innsynkning og oppheving gjennom mesozoikum og kenozoikum. Steile strukturer i berggrunnen danner svakhetssoner ...

    • Sand waves and sediment transport on the SW Barents sea continental slope 

      Waage, Malin (Master thesis; Mastergradsoppgave, 2012-11-15)
      I study a sand-wave field in ~600 meters water depth on the continental slope offshore Northern Norway. Using multibeam bathymetry data from 2008 and 2011 and P-Cable high-resolution 3D seismic data from 2011, I characterize the field. Sand waves reach up to 6.6 m in height and have wavelengths as large as 140 m. They are mostly asymmetric in shape with the steepest side dipping to the northwest, ...

However, the uppermost Glitrefjellet Member is typically poorly exposed in outcrops, and ...

    • Sedimentologiske, paleoøkologiske og diagenetiske undersøkelser av holocene deltaavleiringer ved Breivikeidet, Troms. 

      Evison, Kenneth André (Master thesis; Mastergradsoppgave, 2012-06-04)
      Den nedre delen av Breivikeidet er dominert av postglasiale grunnmarine sedimenter. Den glacio-isostatiske hevning av landmassen har gradvis senket erosjonsbasis og ført til blottleggelse av eldre sedimentene der elvene har skåret seg ned i disse. Den nederste delen av de undersøkte avsettingene er tolket som bottomsets med en rik skeletal fauna dominert av muslinger mens snegler og rester av rur ...
