Non-Gaussian statistical analysis of polarimetric synthetic aperture radar images
(Doctoral thesis; Doktorgradsavhandling, 2011-02-18)
This thesis describes general methods to analyse polarimetric synthetic aperture radar images, with the primary application of unsupervised image segmentation. The fundamental physics of electromagnetic scattering from distributed targets leads to the image phenomenon called speckle. Speckle is shown to be potentially non-Gaussian and several statistical distributions are investigated. Non-Gaussianity ...
U-Pb geochronology of crustal evolution and orogeny Contributions from Caledonide Spitsbergen and the Precambrian West Troms Basement Complex, North Norway

Palaeoenvironment of the Barents Sea during the last deglaciation and Holocene : processes and timing
(Doctoral thesis; Doktorgradsavhandling, 2012-03-01)
The scope of this PhD thesis is twofold: Firstly, processes, patterns and timing of the last deglaciation in the Barents Sea are reconstructed and secondly, depositional conditions on the Barents shelf during Holocene are elucidated. This cumulative PhD thesis encompasses an introductory part and five papers - three as first-author and two as co-author. Three papers are focused on the most prominent ...
The Dayside Open/Closed Field line Boundary -Ground-based optical determination and examination
(Doctoral thesis; Doktorgradsavhandling, 2011-12-20)
The Open/Closed eld line Boundary (OCB) is the most important boundary in the magnetospheric system. On the dayside, the equatorward edge of the 6300 Å[OI] cusp aurora can be used as a proxy for the OCB. This work, which is a dissertation for the degree of philosophiæ Doctor consists of three scienti c papers focusing on the latitude of the optical cusp OCB and one paper focusing on polar cap patch ...
Automatic Inspection of Cod (Gadus Morhua L.) Fillets by Hyperspectral Imaging
(Doctoral thesis; Doktorgradsavhandling, 2011-11-11)
The manual trimming and inspection of cod fillets by candling, is considered the bottleneck of cod fillet processing. The operation is both labour intensive and expensive, reported to account for as much as 50 % of the cost with cod fillet production. Due to the high labour costs in Norway, it is of great interest for the industry to optimize this process. In this work a hyperspectral imaging ...
Rockslide Mapping in Norway by Means of Interferometric SAR Time Series Analysis
(Doctoral thesis; Doktorgradsavhandling, 2011-03-18)
Rockslides have a high socioeconomic and environmental importance in many coun- tries. Norway is particularly susceptible to large rockslides due to its many fjords and steep mountains. One of the most dangerous hazards related to rock slope failures are tsunamis that can lead to large loss of life. It is therefore very important to systemati- cally identify potential unstable rock slopes. In this ...
Relative sea level, deglaciation and tsunami history deduced from isolation basins
(Doctoral thesis; Doktorgradsavhandling, 2010-10-15)
NORSK SAMANDRAG: <br>Denne avhandlinga tek for seg endringane i relativt havnivå – strandforskyvinga – dei siste vel 11.500 åra på kysten av Finnmark og i midtre Hardanger. Ei stor mengd kjerneprøver frå avsettingane i innsjøar som ein gong låg under havnivået, er henta inn og analysert. Grenser mellom sediment som vart avsett i salt- eller ferskvatn er bestemt ved å analysere både kiselalgar ...
Theoretical studies of natural and electromagnetically induced birefringences

Characterization of sub-seabed fluid flow and hydrate systems at Nyegga, offshore mid- Norway : integration of seismic imaging and velocity modeling
(Doctoral thesis; Doktorgradsavhandling, 2010-11-12)
What causes the escape of natural gases to the seafloor and how significant this escape has been along the mid-Norwegian continental margin? These are questions that guided the doctoral thesis. The thesis is part of a research project supported by the European Commission and the Norwegian Research Council, which aims at quantifying geological processes that control fluid flow and gas hydrate formation ...
