Reconstruction of changes in the Weddell Sea sector of the Antarctic Ice Sheet since the Last Glacial Maximum
(Peer reviewed; Journal article, 2014-09-15)A robust understanding of Antarctic Ice Sheet deglacial history since the Last Glacial Maximum is important in order to constrain ice sheet and glacial-isostatic adjustment models, and to explore the forcing mechanisms ... -
Reconstruction of glacier variability from lake sediments reveals dynamic Holocene climate in Svalbard
(Peer reviewed; Journal article, 2015-09-12)The Arctic is warming faster than anywhere else on Earth. Holocene proxy time-series are increasingly used to put this amplified response in perspective by understanding Arctic climate processes beyond the instrumental ... -
Record summer rains in 2019 led to massive loss of surface and cave ice in SE Europe
(Journal article; Peer reviewed, 2021)Glaciers worldwide are shrinking at an accelerated rate as the climate changes in response to anthropogenic influence. While increasing air temperature is the main factor behind glacier mass and volume loss, variable ... -
Record-breaking height for 8000-Year-Old tsunami in the North Atlantic
(EOS : Transactions;Vol. 84, No.31, Journal article, 2003-08-05) -
Reduced El Niño variability in the mid-Pliocene according to the PlioMIP2 ensemble
(Journal article; Peer reviewed, 2021)The mid-Pliocene warm period (3.264–3.025 Ma) is the most recent geological period during which atmospheric CO2 levels were similar to recent historical values (∼400 ppm). Several proxy reconstructions for the mid-Pliocene ... -
Reducing Uncertainties in Carbonate Clumped Isotope Analysis Through Consistent Carbonate-Based Standardization
(Peer reviewed; Journal article, 2018)About a decade after its introduction, the field of carbonate clumped isotope thermometry is rapidly expanding because of the large number of possible applications and its potential to solve long‐standing questions in Earth ... -
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
