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 ...

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 ...

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 ...

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 ...

Natural fractures significantly contribute to improved reservoir quality and recovery factor, especially in carbonate reservoirs. It is important to characterize the matrix and fracture properties, as well as their interaction, in order to describe the natural fracture system and improve the understanding of its effects on a reservoir. This study integrates multi-scale outcrop data from central ...

The Brusque Metamorphic Complex in the Dom Feliciano Belt (Brazil) and the Central Kaoko Zone in the Kaoko Belt (Namibia) represent foreland fold- and thrust belts in external parts of the northern Dom Feliciano-Kaoko orogenic system. Petrographic and field observations of metapelitic samples from the Brusque Metamorphic Complex suggests that the western part of the complex can be subdivided into ...

While most established plays in the Barents Sea have occurred in the Mesozoic, the Alta and Gohta discoveries prove a new carbonate play concept, with a source rock that does not stem from the Jurassic. Based on depositional environment and TOC values from the Palaeozoic interval a source rock with Top Ørn as its bottom and Top Røye as its top was interpreted. Basin modelling carried out on this ...

A geomorphological map has been produced to investigate the glacial history of Aldegondabreen, a small land terminating valley glacier located on the western coast of Spitsbergen. The glacier has changed its dynamic from a tidewater glacier into a land-terminating glacier during the last advance/retreat cycle, and the focus is therefore to reconstruct the glacial history of this cycle. The map ...

Noen veger blir stengt på ubestemt tid på grunn av snøskredfare. Dette er frustrerende for trafikanter og det skaper økonomiske konsekvenser for næringslivet. Statens vegvesen (SVV) har testet ut to teknologier for å detektere og varsle snøskred i sanntid; doppler radar og geofoner. Radaren bruker radiobølger for å måle retning og avstand til et objekt og kan dermed benyttes til å bestemme om skredet ...

Climate change is a comprehensive field of research. The cryosphere is only a small portion of the entire spectrum but is still a very important constituent to try and understand. Thermal expansion of the oceans is the second largest cause for sea level rise around the world after the global melting of glaciers and ice sheets combined. Even the smallest valley glaciers, with small individual volumes, ...
