Geochemical signatures of pingo ice and its origin in Grøndalen, West Spitsbergen
(Peer reviewed; Journal article, 2019)Pingos are common features in permafrost regions that form by subsurface massive-ice aggradation and create hill-like landforms. Pingos on Spitsbergen have been previously studied to explore their structure, formation ... -

Geologisk kartlegging av tunnelalternativ for E39 Myrmel - Lunde, Gaular kommune
(Bachelor thesis, 2015)For ny trasé for E39 Myrmel-Lunde i Gaular kommune, har Statens Vegvesen planlagt å legge veien i tunnel. De har utarbeidet to alternative tunneltraséer med felles påhogg i sør. Kort tunneltrasé er planlagt 600 meter lang, ... -
Geologisk landskapsanalyse av Nordfjord og Eikefjord dreneringssystem
(Bachelor thesis, 2020)Forskere er i dag uenige om hvordan fjellene i Norge har blitt dannet. Debatten har ført til to motstridende hypoteser som prøver å gi en forklaring på fjellenes dannelsesprosess. Den klassiske hypotesen mener at fjellene ... -
Geometry and ice dynamics of the Darwin–Hatherton glacial system, Transantarctic Mountains
(Journal article; Peer reviewed, 2017)The Darwin–Hatherton Glacial system (DHGS) connects the East Antarctic Ice Sheet (EAIS) with the Ross Ice Shelf and is a key area for understanding past variations in ice thickness of surrounding ice masses. Here we present ... -
Geomorfologi og strukturer på det ustabile fjellpartiet Tussen, Luster kommune, Sogn og Fjordane
(Bachelor thesis, 2017)Det potensielle fjellskredområdet Tussen befinner seg i en ØSØ vendt breerodert dalside i den indre delen av Sognefjorden. En kombinasjon av romlig analyse i GIS, feltobservasjoner av struktur og geomorfologi, og DIPS ... -
Geomorphological investigation of multiphase glacitectonic composite ridge systems in Svalbard
(Journal article; Peer reviewed, 2018)Some surge-type glaciers on the High-Arctic archipelago of Svalbard have large glacitectonic composite ridge systems at their terrestrial margins. These have formed by rapid glacier advance into proglacial sediments during ... -
Georadarundersøkelser av Skjerdinganebreen. Beregning av istykkelse, volum og sammenligning av dette med estimerte volumer ved volum-arealmetode
(Bachelor thesis, 2015)Smeltende isbreer er den nest største bidragsyteren til havnivåstigning, etter termal ekspansjon. Små breer (areal < 1km2) har lite volum sett i forhold til større breer og isdekker, men responderer betydelig raskere til ... -
Glacial-lake outburst floods of Harbardsbreen, Western Norway, and their relationship to long-term glacier mass balance and climate change
(Master thesis, 2021)In this study I have used various sources of satellite imagery to present long term changes of the two glacial lakes of Harbardsbreen, Luster municipality, Western Norway. I have made a time series which ranges from the ... -
Glacier algae accelerate melt rates on the south-western Greenland Ice Sheet
(Peer reviewed; Journal article, 2020)Melting of the Greenland Ice Sheet (GrIS) is the largest single contributor to eustatic sea level and is amplified by the growth of pigmented algae on the ice surface, which increases solar radiation absorption. This ... -
Glacier area changes in the central Chilean and Argentinean Andes 1955 – 2013/2014
(Journal article; Peer reviewed, 2016)To improve our knowledge of glacier area changes in the central Chilean and Argentinean Andes (32°9′S–33°4′S), two new glacier inventories from 1989 to 2013/14 are compared with a reinterpreted inventory from 1955. Comparisons ... -
Glacier naled evolution and relation to the subglacial drainage system based on water chemistry and GPR surveys (Werenskioldbreen, SW Svalbard)
(Journal article; Peer reviewed, 2016)Glacier naledi are extrusive ice masses that appear in front of glaciers as a consequence of refreezing of meltwater seepage during the accumulation season. These structures provide a unique opportunity to understand ... -

Glacier thinning, recession and advance, and the associated evolution of a glacial lake between 1966 and 2021 at Austerdalsbreen, western Norway
(Peer reviewed; Journal article, 2023)The Jostedalsbreen is the largest ice cap in Norway and mainland Europe. Rapid retreat of many of its outlet glaciers since the 2000s has led to the formation of several glacial lakes. Processes causing the formation and ... -

Global gene flow releases invasive plants from environmental constraints on genetic diversity
(Peer reviewed; Journal article, 2020)When plants establish outside their native range, their ability to adapt to the new environment is influenced by both demography and dispersal. However, the relative importance of these two factors is poorly understood. ... -
Global sea-level contribution from Arctic land ice: 1971 to 2017.
(Journal article; Peer reviewed, 2018)The Arctic Monitoring and Assessment Program (AMAP 2017) report identifies the Arctic as the largest regional source of land ice to global sea-level rise in the 2003–2014 period. Yet, this contextualization ignores the ... -
Globally elevated chemical weathering rates beneath glaciers
(Peer reviewed; Journal article, 2022)Physical erosion and chemical weathering rates beneath glaciers are expected to increase in a warming climate with enhanced melting but are poorly constrained. We present a global dataset of cations in meltwaters of 77 ...
