Sedimentære miljø, mikrobielle samfunn og porevannkjemi: Sammenligning av sedimenter fra dyphavet og på kontinentalskråningen ved Bjørnøyviften
(Master thesis, 2023-06-06)Hensikten med studien er å undersøke om Mohn-Knipovich ryggen har høyere sedimentasjonsrater og mikrobiell aktivitet enn den nærliggende, grunnmarine kontinentalskråningen sørvest for Bjørnøyrenna. Grunnmarine avsetningsmiljø ... -
Sedimentære prosesser og avsetningsmiljø i Byfjorden, Vest-Norge
(Master thesis, 2015-06-01)Hovedformålene med denne oppgaven har vært å kartlegge sedimentære prosesser og avsetningsmiljø som har forekommet under og etter den siste deglasiasjonen av det Fennoskandiske isdekket i et vest-norsk fjordsystem. Studien ... -
SeeCiTe: a method to assess CNV calls from SNP arrays using trio data
(Journal article; Peer reviewed, 2021)Motivation Single nucleotide polymorphism (SNP) genotyping arrays remain an attractive platform for assaying copy number variants (CNVs) in large population-wide cohorts. However, current tools for calling CNVs are still ... -
Seed banks are biodiversity reservoirs: species–area relationships above versus below ground
(Peer reviewed; Journal article, 2015-05-26)Soil seed banks offer plants the possibility to disperse through time. This has implications for population and community dynamics, as recognised by ecological and evolutionary theory. In contrast, the conservation and ... -
Seedbank, Seedrain and Seedling Recruitment along Climate Gradients in Southern Norway
(Master thesis, 2010-06-01)Recruitment through seeds is a critical process in the life history of plants. Better knowledge about this process may be helpful in predicting species ranges and range shifts under climate change. In western Norway, the ... -
The seeding of ice algal blooms in Arctic pack ice: The multiyear ice seed repository hypothesis
(Peer reviewed; Journal article, 2017-07)During the Norwegian young sea ICE expedition (N-ICE2015) from January to June 2015 the pack ice in the Arctic Ocean north of Svalbard was studied during four drifts between 83° and 80°N. This pack ice consisted of a mix ... -
Seeing the wood for the trees: Carbon storage and conservation in temperate forests of the Himalayas
(Journal article; Peer reviewed, 2021)Forests have a prominent role to play in the success of the UN’s Agenda 2030, thus actions to halt deforestation are high on the international sustainability agenda. As humans are altering the composition and extent of ... -

Segmentation of the Caledonian orogenic infrastructure and exhumation of the Western Gneiss Region during transtensional collapse
(Journal article; Peer reviewed, 2021)The (ultra)high-pressure Western Gneiss Region of the Norwegian Caledonides represents an archetypical orogenic infrastructure of a continent–continent collision zone. To test established exhumation models, we synthesize ... -
Seismic acquisition and analysis in a changing Arctic
(Doctoral thesis, 2020-12-03)In the Arctic, temperatures are regularly low enough that water exists in its frozen state, either in the form of ice, snow, or frozen ground. The effective elastic properties of a material depend on the elastic properties ... -
Seismic Acquisition in a Shallow Marine Sea Ice Covered Environment: The Significance of Survey Geometry and Possible Impacts on Pinnipeds
(Master thesis, 2017-06-27)Seismic surveying of Arctic environments is important for both economic and environmental reasons. The world energy demand is increasing, and new areas need to be explored to cover the demand. One of the new areas where ... -
The Seismic Analyzer: Interpreting and Illustrating 2D Seismic Data
(Peer reviewed; Journal article, 2008)We present a toolbox for quickly interpreting and illustrating 2D slices of seismic volumetric reflection data. Searching for oil and gas involves creating a structural overview of seismic reflection data to identify ... -
Seismic Attributes for Carbonates
(Master thesis, 2009-06-02)Seismic attributes can reveal important information about rock properties, and rock physics modeling provide a link between geological and seismic parameters. Carbonate rocks can have wide variations in properties due to ... -
Seismic characterization of reservoirs with multiple fracture sets using velocity and attenuation anisotropy data
(Journal article, 2011)Knowledge about the spatial distribution of the fracture density and the azimuthal fracture orientation can greatly help in optimizing production from fractured reservoirs. Frequency-dependent seismic velocity and attenuation ... -
Seismic data analysis of an onshore-offshore transition zone at Ramså Basin, Norway – a modelling study

Seismic Event Classification using Machine Learning
(Master thesis, 2021-06-02)The manual detection of seismic events is a labor intensive task, requiring highly skilled workers continuously analyzing recorded waveforms. Previous work has shown the potential of machine learning methods for aiding in ... -
Seismic expression of shear zones: Insights from 2-D point-spread-function based convolution modelling
(Journal article; Peer reviewed, 2020)Shear zones are common strain localization structures in the middle and lower crust and play a major role during orogeny, transcurrent movements and rifting alike. Our understanding of crustal deformation depends on our ... -
A seismic field test with a Low level Acoustic Combustion Source and Pseudo Noise codes
(Journal article, 2007-01-20)The Low level Acoustic Combustion Source (LACS) is a new type of pulsed underwater acoustic source with an output level of 0.5-1.0 barm peak to peak. The source is based on a combustion engine and intended for shallow ... -
Seismic hazard in Norway due to large earthquakes
(Master thesis, 2015-06-01)There are many faults located in Norway, posing as potential earthquake sources. Even though the seismicity is characterized as low to moderate, earthquakes of magnitude 3.5 or lower occur regularly. The seismic hazard ...
