Mid Miocene – Early Pliocene depositional environment on the northern part of the Mid-Norwegian Continental Shelf
(Master thesis; Mastergradsoppgave, 2016-05-15)Based on the study of 2D seismic data, this thesis have focused on the depositional environment during the deposition of the Kai formation (Mid-Miocene – Early Pliocene) on the Mid-Norwegian continental margin, in order to increase our knowledge of the evolution of the paleo-environment in the time-period right before the development of the large Northern Hemisphere ice sheets. Based on a seismic ... -
Modelling laser-matter interactions using resonant states
(Master thesis; Mastergradsoppgave, 2016-05-12)Studying how light interacts with materials has become important for many technological applications from optical communication to developing of new materials. Therefore scientists have always tried to improve their understanding of these effects. The primary goal has always been to microscopically describe the pertinent processes. This paper provides a brief introduction into the interactions of ... -
Reconstruction of ice stream retreat and palaeoceanographic development during the deglaciation and Holocene in the Storfjorden Trough, Svalbard. Based on geophysical data, benthic foraminiferal and sedimentological records
(Master thesis; Mastergradsoppgave, 2016-05-15)Here we investigate the retreat of a palaeo-ice stream and the subsequent palaeoceanographic development in the eastern Storfjorden Trough during the deglaciation and Holocene. The results are based on multibeam bathymetric and acoustic sub-bottom data, and a multiproxy analysis of a 14C dated sediment core (including benthic foraminifera, δ13C, δ18O and sedimentology). The ice stream experienced a ... -

(Master thesis; Mastergradsoppgave, 2016-05-11)Provenance studies reconstruct the erosion and transport history of sediments based on character and composition of deposited sedimentological records with implications for uplift and subsidence of the investigated area. This Master thesis presents a new combination of in situ analytical methods for qualitative provenance studies exemplified on siliciclastic sediments from three offshore exploration ... -
Sedimentation environment during deglaciation and Holocene in Southern Sentralbanken, Barents Sea
(Master thesis; Mastergradsoppgave, 2016-05-15)Grounding zone wedges and ridges throughout the Barents Sea gives good spatial constraints of the Late Weichselian deglaciation of the Barents Sea, however, little is known about Late Weichselian ice dynamics in the Central Barents Sea, primarily due to a lack of data. The study is carried out south of Sentralbanken in Sentralbankrenna which was likely an important source area feeding the Bjørnøyrenna ... -

(Master thesis; Mastergradsoppgave, 2016-05-15)The Trondsvangen-Baugsberget Cu-bearing ore deposits are located in the Tynset-Alvdal region, Hedmark county, central Norway. The earliest documented work in these mines are from the late 17th century, with extensive mining between 1880 and 1911. The ore deposits are located within volcanic and metasedimentary sequences of the Lower Seve Nappes of the Middle Allochthon, Scandinavian Caledonides. The ... -
Argumentasjon i praktiske arbeid. En studie av elevers vurderinger og argumentasjon rundt konkurrerende påstander i forbindelse med et praktisk arbeid i naturfag VG1.
(Master thesis; Mastergradsoppgave, 2015-12-15)Denne oppgaven handler om elevers argumentasjon og vurderinger rundt tre konkurrerende påstander i forbindelse med et praktisk arbeid i naturfag VG1. Elevenes argumentasjon ble kartlagt gjennom to diskusjonsrunder. Den ene diskusjonen var i forkant av forsøket, og foregikk dermed uten datamaterialet. Elevene skulle i denne diskusjonsrunden bruke forkunnskapene de hadde om emnet. Den andre diskusjonen ... -
Lærebokas påvirkning på elevers karakternedgang i Biologi 2
(Master thesis; Mastergradsoppgave, 2015-06-01)Denne studien er en analyse av to læreverk og åtte eksamenssett i faget Biologi 2 på videregående skole. Bakgrunnen for studien var Utdanningsdirektoratets karakterstatistikk, hvor det ble fremstilt at elevene gjennomsnittlig gikk ned omtrent én karakter fra standpunkt til skriftlig eksamen. Studien tok utgangspunkt i at oppgavene i læreboka ikke forberedte elevene godt nok til eksamen. Formålet med ... -

Mer enn bare fakta - En studie av elevers vurderingskompetanse av påstander om proteiner
(Master thesis; Mastergradsoppgave, 2015-06-01)Naturfagundervisning har vært preget av innlæring av faktakunnskaper, og har blitt kritisert for å ha liten sammenheng med den praktiske bruken av faget i samfunnet. Denne oppgaven omhandler et undervisningsopplegg som bygger på samfunnsrelatert undervisning. Hensikten med undervisningsopplegget var å bidra til scientific literacy gjennom elevers evne til å bruke naturfaglig kunnskap i vurdering av ... -
Morfologisk og sedimentologisk undersøkelse av sanduravsetninger foran Steindalsbreen, Lyngen, Tromsø
(Master thesis; Mastergradsoppgave, 2016-05-15)Steindalsbreen som er lokalisert i øvre del av Steindalen, Lyngen har etter siste istid smeltet tilbake. Dette har ført til suksessiv dannelse av tre sandursletter på lavgradients områder i dalbunnen som har blitt eksponert gradvis mens isbreen har smeltet tilbake. Alle tre har ulik alder, distanse til breen, samt horisontal og lateral utbredelse med ulik morfologi. De representerer forskjellig ... -
High frequency financial time series prediction: machine learning approach
(Master thesis; Mastergradsoppgave, 2016-05-13)Machine learning is a rapidly evolving subfield of computer science. It has enormous amount of applications. One of the application domains is financial data analysis. Machine learning was usually applied for analysis and forecasting of daily financial time series. Availability of high frequency financial data became another challenge with its own specifics and difficulties. Regressors, being a ... -

Interaction between ice streaming, glacitectonics and fluid flow in Håkjerringdjupet, SW Barents Sea
(Master thesis; Mastergradsoppgave, 2016-05-13)By using high resolution multibeam swath batymetry and 2- and 3D seismic data this thesis investigate the interactions between ice streaming, glacitectonics and fluid flow in Håkjerringdjupet. The source area for a glacitectonic hill-hole pair is located directly above spatial fluid accumulations assosiated to a fault complex. Glacitectonic deposits are found directly downstream from this area. We ... -
Waveguide Mach-Zehnder interferometer for measurement of methane dissolved in water
(Doctoral thesis; Doktorgradsavhandling, 2016-04-25)In this dissertation, we present the development of a novel, compact and highly sensitive waveguide Mach-Zehnder interferometer to measure methane dissolved in water. Methane is a greenhouse gas, like carbon dioxide, and is emitted from both natural sources and human activities. Due to the challenges to measure dissolved methane in the sea and the vast area it covers, much of the methane cycle is ... -

Fluid flow features and gas hydrates in the outer Vøring Basin
(Master thesis; Mastergradsoppgave, 2015-12-15)The 3D seismic survey ST0827 in the outer Vøring Basin reveals a complex fluid flow system consisting of hydrothermal vents, polygonal faults and acoustic pipes. The polygonal faults are bound to the fine-grained Top Brygge Formation and ooze-dominated Kai Formation. The Kai Formation is overlain by the Naust Formation, in which glacigenic debris flow units are observed. As polygonal faults can be ... -
Modelling the evolution of ideal, infinite domain patterns, on a finite domain using a Perfectly Matched Layer
(Master thesis; Mastergradsoppgave, 2016-01-28)The Swift-Hohenberg equation is an evolution equation which can produce a Pattern, or a pattern-like picture, to be more precise. For example, it could be used to model some simple natural patterns, like stripes and rolls that one may observe in a Rayleigh-Benard convection experiment. But for any pattern formation obtained by an evolution equation to look ideal, we have to consider this equation ... -
North Atlantic warming during Dansgaard-Oeschger events synchronous with Antarctic warming and out-of-phase with Greenland climate
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-02-05)The precise reason for the differences and out-of-phase relationship between the abrupt Dansgaard- Oeschger warmings in the Nordic seas and Greenland ice cores and the gradual warmings in the southcentral Atlantic and Antarctic ice cores is poorly understood. Termed the bipolar seesaw, the differences are apparently linked to perturbations in the ocean circulation pattern. Here we show that ...
