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 bredemde sjøar ved Gråfjellsbrea, Folgefonna
(Master thesis, 2021-09-15)Global oppvarming og smeltande brear fører til aukande fare knytt til stabiliteten av bredemde sjøar og drenering ved jøkullaup. Eit jøkullaup er ei brå tapping av ein bredemd sjø med påfølgjande stor vassføring som igjen ... -
Rekonstruksjon av deglasiasjonsforløpet og havnivåendringar i Valldal, Fjord kommune, Møre og Romsdal, ved bruk av 10Be-eksponeringsdatering og GIS-analysar
(Master thesis, 2021-06-01)Hovudformålet med masteroppgåva er å rekonstruere deglasiasjonsforløpet og havnivåendringane i Valldal, Fjord kommune, for seinglasial tid og holocen. 27 beryllium-10 eksponeringsaldrar frå overflater i Valldal nyttast til ... -
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 ... -
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 ... -
