Modeling and Inversion of CSEM Data using Green's Function Methods
(The University of Bergen, 2014-06-01)
The aim of the present study is to develop new approximations to the integral equation for 3D Controlled Source Electromagnetic (CSEM) synthetic data. Several scattering approximations to the integral equation have previously ...
Seismisk studie av sedimentære prosesser og avsetningsmiljø på Vemafeltet, midtnorsk kontinentalmargin
(The University of Bergen, 2011-12-09)
Denne oppgaven tar for seg havbunnsstrukturer og underliggende linser i Vemafeltet på nordlig del av Vøringplatået. Hovedfokus er på Naustformasjonen som er avsatt i pliocene- pleistocen tid, siden det er innen denne ...
En Paleo-Middelhavs stredavsetning: Kalkarenitter tilhørende Azagadorleddet (miocen), Turreområdet, Almeria, SØ Spania
(The University of Bergen, 2002)
The Vera basin is one of several small, intramontane Neogene basins which developed within the Alpine nappes of the Betic Cordillera of southeastern Spain. This system of interconnected basins acted as a marine strait ...
The seismotectonics of western Skagerrak
The seismically active Skagerrak region in the border area between Denmark and Norway has traditionally been associated with uncertain earthquake locations due to the limited station coverage in the region. A new seismic ...
Dissolved gases in hydrothermal plumes from Artic vent fields
(The University of Bergen, 2013-10-30)
Recent discoveries of active vent fields on slow and ultraslow spreading ridges have revealed that hydrothermal activity is more common than previously assumed. In the Norwegian-Greenland Sea, two such vent fields are ...
Exploring the Microseismicity of the Gakkel Ridge from Arctic Sea Ice
(The University of Bergen, 2013-06-03)
Monitoring of microseismicity is an important tool to understand the magmatism, tectonics and hydrothermal circulation of a mid-oceanic ridge. In the presence of sea ice, use of ocean bottom seismometers is not practical, ...
Isotopic composition of Pb in tree rings of Norway spruce (Picea abies) from the Fensfjorden area, western Norway
(The University of Bergen, 2012-06-01)
The annual growth of tree rings makes the trees as possible archive of the past atmospheric pollution. However, several aspects addressed in literature such as post-depositional mobility of Pb, intra-ring heterogeneity ...
Gravity modeling: Calculations based on porosity-density context
(The University of Bergen, 2010-06-17)
A normal way to model the gravity from a layered model is to determine the densities from the velocities, and then adjusting the densities within acceptable ranges to get a satisfactory fit with the observed gravity. In ...
Physical and Chemical Processes in the Bjerkreim-Sokndal Magma Chamber
(The University of Bergen, 2010-03-19)
Deformation of sandstone reservoirs. Insight from experiments and field studies
(The University of Bergen, 2014-09-18)
