    • Integrated characterization of igneous intrusions in Central Spitsbergen 

      Festøy, Marte Hergot (Master thesis; Mastergradsoppgave, 2017-05-15)
      Igneous intrusions have a strong influence on petroleum systems, groundwater aquifers, and CO2 storage reservoirs, particularly because they can act as either barriers to, or carriers for fluid flow. This depends on several syn- and post emplacement processes, including fracture development in the intrusion and the host rocks, contact metamorphism of the host rocks, and hydrothermal activity. ...

Glacitectonic deposits are found directly downstream from this area. We ...

    • Interaction of submarine tailings with natural sediments in three northern Norwegian coastal areas. Sedimentological, mineralogical and geochemical constraints 

      Figenschau, Nikolai (Master thesis; Mastergradsoppgave, 2018-05-15)
      Submarine tailings placements (STPs) is an alternative practice of handling mine waste, which involves deposition of tailings into submarine environments. However, the environmental impacts of STPs remain poorly understood. This thesis is a contribution to improve the understanding of how submarine tailings placements interact with natural sediments. It is based on multi-proxy analyses of 10 sediment ...

    • Kortejärvi Veiki moraine plateau - a key to the glacial history of northern Sweden 

      Lindqvist, Mimmi Adina (Master thesis; Mastergradsoppgave, 2020-03-30)
      In many parts of Scandinavia, the glacial history is more well established than in northern Sweden. The Veiki moraines in northeastern Sweden presumably store information about the Weichselian glaciations. The moraines were formed when stagnant ice was slowly melting under a thick debris cover, forming water filled sinkholes, that were left as elevated ice-walled lake plains when the ice finally ...

    • Last Glacial Maximum – Holocene palaeoenvironment in Bessel Fjord and southwestern Dove Bugt, Northeast Greenland 

      Zoller, Kevin Michael (Master thesis; Mastergradsoppgave, 2020-05-14)
      Marine studies reconstructing ice sheet conditions on the Northeast Greenland shelf and adjacent fjords since the Last Glacial Maximum (LGM) are sparse. As a result, the timing and origin of the deglaciation of the ice sheet over marine areas is not well constrained. This thesis aims to improve our understanding of the LGM, deglaciation, and Holocene ice dynamics of the Greenland Ice Sheet (GrIS) ...
