  • Morfologisk og sedimentologisk studium av det moderne og hevede Storfjorddeltaet, Troms 

    Jensen, Lisbeth (Master thesis; Mastergradsoppgave, 2018-07-05)
    Denne oppgaven består i å undersøke det aktive Storfjorddeltaet med hensyn på morfologi og sedimentologi. Den hevede delen av deltaet ble også undersøkt ved 3 snitt for å finne ut hvordan deltaet hadde progradert for omtrent 3000 år siden og frem til i dag. Kartlegging og flybilder ble brukt, i tillegg til siling av prøver og datering av materiale. Resultatet ble at deltaet er klassifisert som et ...
  • Source of CO2 in large Talc-Carbonate veins in serpentinites of the Zermatt-Saas Fee unit

    Strømme, Kristine (Master thesis; Mastergradsoppgave, 2019-05-15)
    The late Quaternary evolution of the outer Ingøydjupet area (SW Barents Sea) is studied using a merge of conventional 3D-seismic cubes and a new generation of high-resolution 3D-seismic (TopSeis). The glacigenic sequence is subdivided into five main seismic units: unit A1 (oldest) to A5. These are separated by six glacially eroded boundaries: the Upper Regional Unconformity (URU), intra-glacial ...
