Unstable areas producing rock slope failures come with large consequences. The understanding of why and where they might occur is necessary to mitigate damage and prevent casualties. A total of 133 unstable rock slopes have been detected in Troms, Northern Norway, evidencing that a great focus on these geohazards is important. This study has focused on seven unstable rock slopes in Kåfjorden, Troms, ...

Sedimentkjerne NP05-11-21GC fra Kongsfjordrenna vest for Spitsbergen er analysert for å kartlegge utviklingen av paleomiljø de siste ~11 800 år. Analysene er basert på undersøkelser av bentiske foraminiferer og sedimentologiske egenskaper. Kjernen er 5,15 meter lang og 104 prøver er analysert med hensyn på fauna, droppstein og kornfordeling. Sedimentenes fysiske egenskaper er målt ved hjelp av en ...

This Master thesis investigates the relationship between glacial erosion, glaciotectonically displaced sediment blocks and indications of fluid flow and shallow gas accumulations in buried glacial sediments of the south-western Barents Sea margin. The thesis is based on two three-dimensional (3D) seismic datasets, NH98003 and EL0001, the two-dimensional (2D) seismic survey NH9702 and exploration ...

The Nordmannvik nappe (Lyngen fjord, northern Norway) is a high grade tectonic unit dominated by mylonitic garnet-kyanite-mica gneisses, with additional calc-sillicates, mafics and high grade relics. The unit was principaly deformed during the Scandian event of the Caledonian orogeny, reaching at least an upper amphibolite facies. A metamorphic peak, set at a minimum of 750°C / 0.9 GPa, has been ...

Rockfalls and snow avalanches are a major natural hazard and common phenomenon in mountainous areas in Norway, endangering people and infrastructure. Svarthola, on Fv 862, Senja, is a 100 m long unprotected stretch of road that experiences a high frequency of mass movements. The road is situated at a tunnel portal, between a 100 m high cliff and the fjord. As such, it is the only short access route ...

The overall aim of this thesis is to better understand the development and emplacement of diapiric mound features in the Vema Dome area, located in the Vøring basin on the mid-Norwegian continental margin. Two 3D seismic surveys, ST9603R99 and BPN9601, were interpreted in this study, in order to investigate the diapiric mounds and their relationship with an underlying fluid plumbing system including ...

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 ...

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, ...

Multi-proxy analyses of the giant piston core MD992301 (including lithostratigraphy, physical properties and XRF-scanning) and analyses of swath bathymetry data was integrated in order to reconstruct the glacial history and paleoenvironment of the distal parts of the INBIS channel, located between the distal Bear Island Trough Mouth Fan and Storfjorden Trough Mouth Fan. Based on the swath bathymetry ...

Low-resolution bathymetry, high-resolution seismic data (chirp) and multi-proxy analyses of three sediment gravity cores were integrated to study sedimentary processes with the purpose of reconstructing paleoenvironments in the three north Norwegian fjords Øksfjorden, Bergsfjorden and Jøkelfjorden since the last glacial. These three fjords are located on the Bergsfjorden peninsula and surround the ...
