Alps to Apennines zircon roller coaster along the Adria microplate margin
(Peer reviewed; Journal article, 2018-02-09)We have traced the particle path of high-pressure metasedimentary rocks on Elba Island, Northern Apennines, with the help of a U-Pb-Hf detrital zircon study. One quarter of the analysed zircons are surprisingly young, ... -
Ambient noise levels and detection threshold in Norway
(Peer reviewed; Journal article, 2016-07)Ambient seismic noise is caused by a number of sources in specific frequency bands. The quantification of ambient noise makes it possible to evaluate station and network performance. We evaluate noise levels in Norway from ... -
Ambient noise levels, QLg wave tomography and earthquake source parameters in Norway
(Doctoral thesis, 2019-04-05)Norway is part of an intraplate environment and therefore experiences low to intermediate seismicity. This seismicity is a response to the stress eld in the lithosphere, which is mainly in uenced by ridge push from the ... -
Ammonia-oxidizing archaea have similar power requirements in diverse marine oxic sediments
(Journal article; Peer reviewed, 2021)Energy/power availability is regarded as one of the ultimate controlling factors of microbial abundance in the deep biosphere, where fewer cells are found in habitats of lower energy availability. A critical assumption ... -
An investigation on the development of liquid water content in different snow types during slushflow-inducing weather conditions
(Master thesis, 2024-06-03)Slushflows, defined as rapid mass-movements of water-saturated snow, occur when high liquid water content (LWC) causes bonds to melt and the snowpack to lose cohesion, triggering flow. Characterized by their shallow release ... -

Analysis of Deformation Data at Grímsvötn (Iceland) Reveal Viscoelastic and Cyclic Magma Chamber Dynamics
(Master thesis, 2024-06-03)Volcanic eruptions are quite unpredictable and pose a great hazard to humans and society. The most efficient way to mitigate this hazard is through improved understanding of volcanic systems. This can be done through ... -
Analysis of storm surge events along the Norwegian coast
(Journal article; Peer reviewed, 2023-02-08)Observed extreme sea levels are caused by a combination of extreme astronomical tide and extreme storm surge, or by an extreme value in one of these variables and a moderate value in the other. We analyzed measurements ... -
Analytical and numerical studies of fluid reservoirs and fracture development in heterogeneous rocks
(Doctoral thesis, 2009-06-29) -
Anatomy and allostratigraphy of deep-marine Mount Messenger Formation (Miocene), eastern-margin Taranaki Basin, New Zealand
(Master thesis, 2003)Purpose of study: Sedimentological description of outcropping deep-water clastics within Mount Messenger Formation. Study area: North-Taranaki coastal region, North Island, New Zealand. Methodology: Mapping on foot and ... -
Anisotropic Properties of a Mid-Lithospheric Discontinuity in eastern North America
(Master thesis, 2017-06-23)During the last few years the occurrence of a mid-lithospheric discontinuity (MLD) has been observed in lithospheric studies of cratons. Studies using receiver functions have focused mainly on extracting high resolution ... -
Anisotropic Structure of the Core-Mantle Boundary Using Core-Reflected Phases
(Master thesis, 2024-06-03) -
Anoxic Sediments & Ice Coverage: Severe Winter Climate Indicators in the Acrctic from Lake Stuptjørna, Svalbard
(Master thesis, 2024-08-05)The Arctic is experiencing accelerated climate change, which has global significance. Changes in temperature and precipitation in the region affect glacier and ice cap dynamics, sea ice extent, eustatic sea level rise, and ... -
Anthropogenic and environmental drivers of vegetation change in southeastern Norway during the Holocene
(Journal article; Peer reviewed, 2021)Uncovering anthropogenic and environmental drivers behind past biological change requires integrated analyses of long-term records from a diversity of disciplines. We applied an interdisciplinary approach exploring effects ... -
Antropogen påvirkning og bæreevne i turistgrotter: Grønligrotta, Mo i Rana
(Master thesis, 2018-06-20)Grønligrotta er den eneste turistgrotta i Norge med innlagt belysning og god tilrettelegging for turister. Hensikten med denne masteroppgaven har vært å undersøke hvordan turistene påvirker miljøet i grotta, og om dette ... -
Application of Clumped Isotope Thermometry to Benthic Foraminifera
(Peer reviewed; Journal article, 2019-04)Obtaining absolute temperatures of the ocean in deep time is complicated by the lack of constraints on seawater chemistry. Seawater salinity, carbonate ion concentration, δ18O, and elemental abundance changes may obscure ... -
Application of in-situ gamma spectrometry for radiogenic heat production estimation in the Western Himalaya, Kohistan, and Karakoram in northern Pakistan
(Journal article; Peer reviewed, 2023)The Himalaya, Kohistan, and Karakoram ranges comprise Proterozoic to Cenozoic crystalline complexes exposed in northern Pakistan. Numerous hot springs in the area indicate high subsurface temperatures, prompting a need to ... -
Applied Structural Geology – Case Studies of Underground Constructions and Rockslides
(Doctoral thesis, 2008-02-26)An understanding of the structural elements in the sub-surface is of great importance when establishing new constructions in bedrock, or surveying areas prone to rockslides. In this thesis the focus has been on combining ... -
