Refining benthic foraminiferal Mg/Ca-temperature calibrations using core-tops from the western tropical Atlantic: Implication for paleotemperature estimation
(Peer reviewed; Journal article, 2013-04)Benthic foraminiferal Mg/Ca has been shown to have great potential as a proxy for reconstructing deep water temperatures. However, the exact relationship between Mg uptake in benthic foraminifera and temperature is still ... -
Regional correlation and seismic stratigraphy of Triassic Strata in the Greater Barents Sea: implications for sediment transport in Arctic basins
(Journal article; Peer reviewed, 2020)The Greater Barents Sea Basin (GBSB) in Arctic Russia and Norway is an intracratonic basin that accommodated an enormous amount of sediment during the Triassic. These deposits are up to 4.5 km thick over an area 2,500,000 ... -
Rekonstruksjon av flommer i Vossovassdraget de siste tusen år
(Master thesis, 2018-06-20)Lake sediments have the potential to register past flood events beyond historical and instrumental archives. In this study, several sediment cores from the bottom of lake Vangsvatnet have been studied to identify flood ... -
Rekonstruksjon av holosen breaktivitet i vestlig sektor av Nordfonna, Folgefonna. En studie basert på analyser av innsjøkjerner og kvartærgeologisk kartlegging
(Master thesis, 2014-06-02)Denne masteroppgaven fokuserer hovedsakelig på bre- og klimafluktuasjoner i vestlig sektor av Nordfonna, Folgefonna. Arbeidet vil baseres på 1) kvartærgeologisk kartlegging av områdene rund brefronten til Juklavassbreen ... -
Rekonstruksjon av innlandsisen i Geiranger i yngre dryas og kvartærgeologisk kartlegging av Grinddalen
(Master thesis, 2018-06-13)The coastal areas of Sunnmøre has been subject to several previous studies, and they show that these areas were ice-free early in the deglaciation after LGM (last glacial maximum). Less research has been done on the ... -
Rekonstruksjon av isavsmeltingsforløpet i Gråsteindal-området, indre Sunnmøre
(Master thesis, 2017-12-07)The North-Western part of Norway became ice free during the Late Weichselian glaciation and the ice margin is mapped across several fjord districts. Distinct moraine systems in the high mountains indicate an extensive local ... -
Rekonstruksjon av isbevegelsesretninger basert på flyttblokker, Heidalsmuen (1745 m o.h.), Sel i Oppland
(Master thesis, 2013-06-03)En provenancestudie av flyttblokker legger grunnlaget for en rekonstruksjon av isbevegelsesretninger over fjellet Heidalsmuen (1745 m o.h.) i Sel i Oppland. Resultatene viser at to isbevegelsesretninger kan antydes, (I) ... -
Rekonstruksjon av skredaktiviteten rundt Langfjordvatnet på Arnøy, Nord-Troms. Ein studie basert på kvartærgeologisk kartlegging og analysar av innsjøkjernar
(Master thesis, 2012-07-16)In this study from Lake Langfjordvatnet at Arnøy, northern Troms, a large rock slope failure has been mapped and dated. In addition the Holocene snow avalanche activity has been reconstructed based on layers of avalanche ... -
Rekonstruksjon av storflommer i Tovdalsvassdraget gjennom holocen, ved terskelinnsjøen Berse
(Master thesis, 2020-07-04)Tovdalsvassdraget på Sørlandet domineres i dag av høstflommer som følge av store nedbørshendelser, men enkelte vårflommer forekommer. I denne studien er flomarkivet for Tovdalsvassdraget utvidet utover de instrumentelle ... -
The relationship between fluid flow, structures, and depositional architecture in sedimentary rocks: An example-based overview
(Journal article; Peer reviewed, 2020)Fluid flow in the subsurface is fundamental in a variety of geological processes including volcanism, metamorphism, and mineral dissolution and precipitation. It is also of economic and societal significance given its ... -
Relative continent - mid-ocean ridge elevation: a reference case for isostasy in geodynamics
(Journal article; Peer reviewed, 2022)The choice of crustal and mantle densities in numerical geodynamic models is usually based on convention. The isostatic component of the topography is not calibrated to fit observations resulting in not very well constrained ... -
Relocating Earthquakes using Seismic Networks on Small Islands: Case Studies from Heimaey (Iceland) and Jan Mayen (Norway)
(Master thesis, 2019-08-24)The main objective of this thesis is to study different aspects of solving the earthquake location problem and to investigate difficulties in locating earthquakes with sparse networks. This was done by using different ... -
A Remote Sensing Investigation into the evolution of Folgefonna Glacier over the last 150 years
(Master thesis, 2012-05-19)The evolution of Folgefonna, three large maritime ice masses in Hardanger, Western Norway has been assessed over the last 150 years using a variety of remote sensing datasets (optical and microwave satellite images, aerial ... -
Reorganization of Atlantic Waters at sub-polar latitudes linked to deep-water overflow in both glacial and interglacial climate states
(Journal article; Peer reviewed, 2022)While a large cryosphere may be a necessary boundary condition for millennial-scale events to persist, a growing body of evidence from previous interglacial periods suggests that high-magnitude climate events are possible ... -
