The metasediementary rocks of the Coastal Terrane in the Kaoko Belt (Namibia) and the meta-igneous rocks of the Punta del Este-Terrane in the Dom Feliciano Belt (Uruguay) both share one high-grade metamorphic event at approximately the same time of c. 650-630 Ma. Metamorphic conditions of this high-grade event were estimated in four samples from the Punta del Este Terrane and two samples from ...

Enterprise wireless networks are becoming larger and larger, with more and more users and devices connecting to the networks. This requires the infrastructure to be closely monitored and adjusted to ensure an optimum experience for users and their devices. Existing proprietary solutions exist, but are either costly, resource demanding, rigid or may not be able to deliver the functionality that is ...

The oil and gas installations are associated with risk due to different degradation mechanisms. Microbial Influenced Corrosion, commonly known as MIC, is one of them. The failures caused by MIC may have significant impacts on health, safety and environment (HSE). Therefore, to avoid failures regular inspection of the assets and maintenance plans need to be executed. With this on mind, engineers try ...

We find that summer methane (CH4) release from seabed sediments west of Svalbard substantially increases CH4 concentrations in the ocean but has limited influence on the atmospheric CH4 levels. Our conclusion stems from complementary measurements at the seafloor, in the ocean, and in the atmosphere from land-based, ship and aircraft platforms during a summer campaign in 2014. We detected high ...

In this thesis a series of geophysical surveys are carried out on the geologically important and remote Svalbard using magnetotelluric imaging, to constrain better the geology particularly defining geothermal resources. Magnetotellurics (MT) relays on natural source time-varying electric and magnetic field data measured at the earth’s surface in order to derive the subsurface resistivity structure. ...

On Uløya, an island located east of the Lyngen peninsula in northern Troms, Norway, four Caledonian nappes are exposed. These are from bottom to top: part of the Kalak Nappe Complex (KNC), the Vaddas, the Kåfjord and the Nordmannvik nappe. In the present study the geology of these nappes is described, macroscopic and microscopic deformation structures are analyzed, and phase equilibrium modeling is ...

The effect of surfaces and interfaces on the molecular properties and structure is of a great interest in the applied sciences and technology. In the following thesis, a theoretical framework for the calculations of the free energy and properties, including the effect of interfaces and surfaces, in quantum-mechanical formalism is presented. The model of choice is Polarizable Continuum Method (PCM), ...

This thesis has focused on the depositional environments of the Upper Triassic Snadd Formation. This formation covers the time-period Ladinian to early Norian with multiple marine regressions and transgressions, resulting in depositional environments ranging from offshore marine shelf to a coastal plain. A 3D seismic dataset and its correlating well have been studied and a refined seismic stratigraphic ...

Large seabed depressions in the Ingøydjupet Trough have previously been interpreted to be formed by sub-glacial melt-water. However, fluid migration and gas expulsion occur over large parts of the Barents Sea, which are frequently associated with seabed depressions. This thesis studies how the seabed depressions are related to sub-surface canyons on the southern part of the Loppa High, SW Barents ...
