Geomorfologiske og kvartærgeologiske studier i og omkring midtre Gudbrandsdal
(Master thesis, 1962) -
Geomorphological processes shape plant community traits in the Arctic
(Journal article; Peer reviewed, 2022)Aim Geomorphological processes profoundly affect plant establishment and distributions, but their influence on functional traits is insufficiently understood. Here, we unveil trait–geomorphology relationships in Arctic ... -
Geophysical investigation of the Hugin Fracture, a soft-sediment seafloor fracture on the Utsira High, North Sea. Implications for subsurface fluid migration
(Doctoral thesis, 2019)The 2011 discovery of the Hugin Fracture, a 3.5 km long seafloor fracture on the Utsira High, shows that large-scale, unexpected features can still be found in ostensibly wellmapped, highly industrialized offshore areas ... -
Germination and seedling growth of Calluna vulgaris is sensitive to regional climate, heathland succession, and drought
(Journal article; Peer reviewed, 2023)The coastal heathlands of Northwest Europe are highly valued cultural landscapes, that are critically endangered due to land use and climatic changes, such as increased frequency and severity of drought events. Our study ... -
Germination ecology of the clonal grassland herb Knautia arvensis: Regeneration strategy and geographic variation.
(Peer reviewed; Journal article, 2003)We investigated germination responses and seed recruitment in the clonal grassland herb Knautia arvensis (Dipsacaceae) throughout the species’ distributional range in Norway. Four predicted relationships between germination ... -
A giant reconstruction of α-quartz (0001) interpreted as three domains of nano dauphine twins
(Peer reviewed; Journal article, 2015-10-08)Silica (SiO2) is one of the most common materials on Earth. The crystalline form α-quartz is the stable silica polymorph at ambient conditions although metastable forms exist. α-quartz is a piezoelectric material, it can ... -
Giant sponge grounds of Central Arctic seamounts are associated with extinct seep life
(Journal article; Peer reviewed, 2022)The Central Arctic Ocean is one of the most oligotrophic oceans on Earth because of its sea-ice cover and short productive season. Nonetheless, across the peaks of extinct volcanic seamounts of the Langseth Ridge (87°N, ... -
Gill and labial palp areas in blue mussels (Mytilus edulis) at sites with different food quantity
(Master thesis, 2013-06-01)Suspension feeding bivalves captures and process particles with their gills and labial palps. These foraging apparatus are known to be flexible in size related to seston quantity and quality. It is important to understand ... -
The gill parasite Paramoeba perurans compromises aerobic scope, swimming capacity and ion balance in Atlantic salmon
(Peer reviewed; Journal article, 2017-01)The parasitic amoeba Paramoeba perurans is an aetiological agent of amoebic gill disease (AGD), a serious problem in seawater salmonid aquaculture globally. Other finfish species are also infected and infection events may ... -
Giving eyes to pelagic trawls: Acoustic and optical techniques measure behaviour, species, and sizes of fish in situ
(Doctoral thesis, 2013-11-26)Trawling, towing a cone-shaped net behind a moving boat, is a widespread fishing method both in commercial fisheries and to collect fish for scientific investigations. It combines filtering effect with herding behaviour ... -
Gjennom grottekartlegging og kjemiske analyser studere lengdesnittet av Plurdalen og dannelsen av Pluragrotta
(Master thesis, 2015-05-31)Denne oppgaven har hatt som formål å studere lengdesnittet av Plurdalen i Rana. Metoden har vært tredelt i form av grottekartlegging, lokalisering av erosjonsbasis og utføring av kjemiske vannanalyser. Det ble kartlagt ... -
Gjennom grottekartlegging, kjemiske analyser av litologien og strukturgeologiske målinger, danne en plausibel dannelsesmodell for Burfjellgrotta, Rana, Nordland
(Master thesis, 2014-06-02)Denne oppgaven er en del av Glomdalsprosjektet og er knyttet opp til nykartleggingen av Burfjellgrotta høsten 2012. Den har som formål å bidra til økt innsikt i glasial påvirkning på grottedannelse i høyereliggende områder. ... -
Glacial microbiota are hydrologically connected and temporally variable
(Journal article; Peer reviewed, 2020)Glaciers are melting rapidly. The concurrent export of microbial assemblages alongside glacial meltwater is expected to impact the ecology of adjoining ecosystems. Currently, the source of exported assemblages is poorly ... -
Glacier and ocean variability in Ata Sund, west Greenland, since 1400 CE
(Journal article; Peer reviewed, 2020)To improve knowledge of marine-terminating glaciers in western Greenland, marine sediment cores from the Ata Sund fjord system, hosting two outlet glaciers, Eqip Sermia and Kangilerngata Sermia, were investigated. The main ... -
Glacier dynamics in the fjords of Svalbard, inferred from submarine landforms and marine sediment cores
(Doctoral thesis, 2017-09-19)This thesis presents a reconstruction of the late Weichselian, deglacial and Holocene glacial history of the Svalbard fjords, focusing on eastern Svalbard. The study is based on high-resolution multibeam data, shallow ... -
Glacier retreat alters downstream fjord ecosystem structure and function in Greenland
(Journal article; Peer reviewed, 2023)The melting of the Greenland Ice Sheet is accelerating, with glaciers shifting from marine to land termination and potential consequences for fjord ecosystems downstream. Monthly samples in 2016 in two fjords in southwest ... -
Glacier thinning, recession and advance, and the associated evolution of a glacial lake between 1966 and 2021 at Austerdalsbreen, western Norway
(Journal article; Peer reviewed, 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 ... -
Glacigenic sedimentation pulses triggered postglacial gas hydrate dissociation
(Peer reviewed; Journal article, 2018-02-12)Sediment cores from the south-eastern Nordic Seas simultaneously archive the variability of the Fennoscandian Ice Sheet (FIS), the British-Irish Ice Sheet (BIIS) and the regional oceanic conditions. This study aims to ... -
