Strandforskyving og isavsmelting i midtre Hardanger
(Master thesis, 2005)A new Holocene relative sea-level (RSL) curve is drawn, based on three firmly dated isolation basins in mid-Hardangerfjorden, southwest Norway. Several AMS-datings of Betula leaves from each isolation contact yielded very ... -
Evidence for three North Sea tsunamis at the Shetland Islands between 8000 and 1500 years ago
(Journal article, 2005-08)Coastal fen- and lake deposits enclose sand layers that record at least three Holocene tsunamis at the Shetland Islands. The oldest is the well-known Storegga tsunami (ca 8100 cal yr BP), which at the Shetlands invaded ... -
Down-dip correlation and modelling of shallow-marine and estuarine deposits in the Sunnyside Member, Book Cliffs, Eastern Utah: implications for the formation of non-depositional discontinuity surfaces
(Master thesis, 2005-11)The Sunnyside Member is part of the Blackhawk Formation and consists of shallow-marine and estuarine deposits reflecting high-frequency changes in sea level. Detailed mapping of the unit reveals an intra parasequence ... -
Den klimatiske og oseanografiske utviklingen over Vøringplatået i perioden Preboreal til Midt-Holosen
(Master thesis, 2006)Dette studiet er basert på en sedimentkjerne som er hentet fra sørlige deler av Vøringplatået (64°45.928’N, 04°46.195’Ø) i Norskehavet. På grunn av sin strategiske plassering i forhold til sirkulasjonsmønsteret, er ... -
Senglasiale vulkanske askelag i innsjøsedimenter på Vestlandet
(Master thesis, 2006-03-15)A sediment core from a peat bog on Dimnøy at Sunnmøre, western Norway has been investigated in order to search for volcanic ash horizons. A new volcanic ash with a geochemistry more or less identical to the rhyolitic ... -

Late Weichselian relative sea-level changes and glacial history in Hordaland, Western Norway
(Doctoral thesis, 2006-05-19)Two well dated lateglacial relative sea-level curves have been constructed from Hordaland, western Norway, by the isolation basin method. The easternmost curve is based on six basins from the Os area, close to the Younger ... -
Seismic depth imaging of complex structures An example from Zagros fold and thrust belt, Iran

Paleoceanography and paleoclimate in the Nordic Seas and the northern North Atlantic during the last 22 000 years
(Doctoral thesis, 2006-09-01)The paleoceanography of the Nordic Seas and the northern North Atlantic during glacial and deglacial times was studied, using oxygen isotopes and Mg/Ca of foraminifera. The specific objectives are listed below: 1) Sea ... -
Numerical simulation of turbidity currents: a new perspective for small- and large-scale sedimentological experiments
(Master thesis, 2007)Turbidity currents are a variety of subaqueous sediment-gravity flows, in which the suspension of sediment by water turbulence produces a water-sediment mixture that is denser than the ambient water and hence flows due to ... -
The start of a major sea-level rise indicates that icesheet expansion in western Norway commenced before the Younger Dryas
(Journal article, 2007)The relative sea level rose 10 m on Sotra, western Norway, during the Younger Dryas (YD). Based on dating of isolation basins, the transgression started in late Allerød at ~13 110 and ended in late YD at ~11 780 cal yr BP, ... -
Inception of the Northern European Ice Sheet due to contrasting ocean and insolation forcing
(Peer reviewed; Journal article, 2007-01)About 115,000 years ago the last interglacial reached its terminus and nucleation of new ice sheet growth was initiated. Evidence from the northernmost Nordic Seas indicate that the inception of the last glacial was related ... -
Seismic properties of carbonate rocks with emphasis on effects of the pore structure
(Doctoral thesis, 2007-06-18) -
Ice-sheet dynamics and glacial development of the Norwegian continental margin during the last 3 million years
(Doctoral thesis, 2007-06-29)This thesis is mainly about the dynamics of the palaeo-ice sheets that covered Scandinavia, Barents Sea and Svalbard during the last glaciation. Morphological interpretation of regional and detailed bathymetric data sets ... -
A late-winter to early-spring temperature reconstruction for southeastern Norway from 1758 to 2006
(Peer reviewed; Journal article, 2007-10)Systematic temperature observations were not undertaken in Norway until the early 19th century, and even then only sporadically. Climate-proxy data may be used to reconstruct temperatures before this period, but until now ... -
High-Resolution Environmagnetic Study of HOTRAX Core JPC-14 from the Alpha Ridge, Arctic Ocean
(Master thesis, 2007-11-19)Core JPC-14 was derived from the HLY-0503 expedition from the Alpha Ridge. My supervisor professor Reidar Løvlie guided me with the project, from experiments, data obtaining, and analyisis.
