-
(Master thesis / Masteroppgave, 2018)Recent studies show that the noise recorded by seismic sensors can be used to characterize the seismic structure in the area where the sensors are located. This is called ambient noise tomography. In this thesis, data from ...

Application of Spectral Time-Domain Induced Polarization in Engineering Geophysics - A study on black shale in the Oslo GrabenRestricted Access (Master thesis / Masteroppgave, 2017)
-
Asessing offshore geohazards: seismic integration and velocity-model building at the ICG Finneidfjord lab site, NorwayRestricted Access (Master thesis / Masteroppgave, 2014)
-
(Master thesis / Masteroppgave, 2019)The aim of this thesis has been to look at the possibility of using a convolutional neural network to attenuate seismic interference (SI) noise in marine seismic data. Modern SI-denoising algorithms employed by the industry ...

-
(Master thesis / Masteroppgave, 2016)Several studies have been conducted since last 50 years to understand the crustal architecture of the passive margins. The conjugate passive margins along Indian Ocean are very less surveyed and studied due to geographical ...
-
(Master thesis / Masteroppgave, 2020)Oxia Planum is the chosen landing site for the ExoMars2022 rover that launches between August and October 2022. The nominal mission is one Mars year, and the goal is to look for signs of past or present life on Mars. The ...
-
(Master thesis / Masteroppgave, 2014)The Eggvin Bank is a shallow area located on the northern segment of Kolbeinsey Ridge. Its crustal structure was investigated along a 301 km long transect from the Greenland Basin to the Iceland Plateau, crossing over the ...
-
(Master thesis / Masteroppgave, 2016)This thesis is an investigation of currents in the outer Oslofjord using available tools. Current records and output from the NorKyst-800 model are examined and compared using statistical methods. Internal tidal waves are ...

-
(Master thesis / Masteroppgave, 2011)This thesis investigates the application of the Empirical Mode Decomposition (EMD) and Ensemble Empirical Mode Decomposition (EEMD) techniques in de-noising of marine seismic data. EMD decomposes the seismic dataset into ...
-
(Master thesis / Masteroppgave, 2021)AbstractMt. Bromo is a strombolian-type volcano in East Java, Indonesia, that entered into one of its main eruption periods; between November 2015 and January 2016. The activity was registered by several seismic stations, ...

-
(Master thesis / Masteroppgave, 2014)The main focus of this thesis work has been diffractions and their associated multiples in marine seismic. Since diffraction carry useful information about small scale inhomogeneities in general, techniques able to enhance ...
-
(Doctoral thesis / Doktoravhandling, 2009)Magma transport through the Earth’s crust often ends in sedimentary basins. While it erupts at the surface, a significant part of the magma emplaces in depth in the basin forming sheet complexes dominated by horizontal ...

-
(Master thesis / Masteroppgave, 2010)In a 3D marine survey, often large areas of poor coverage (‘coverage holes’) exist caused by feathering during the actual acquisition. Infill management is introduced to fill those ‘coverage holes’, but a high percentage ...
