Crystallographic orientation mapping of lizardite serpentinite by Raman spectroscopy
(Journal article; Peer reviewed, 2022)The serpentine mineral lizardite displays strong Raman anisotropy in the OH-stretching region, resulting in significant wavenumber shifts (up to ca. 14.5 cm−1) that depend on the orientation of the impinging excitation ... -
Sen-holocene maringeologiske avsetningsprosesser i Førdefjorden
(Master thesis, 2022-06-01)Fjordlandskapet langs den vestnorske kysten er viktige maringeologiske arkiv grunnet deres semi-isolerte morfologi. Fjordbassengenes sedimentære avsetninger består hovedsakelig av sediment knyttet til proksimale- og distale ... -
Holocene skredhendingar i Sulafjorden og på Hareidlandet, Sunnmøre
(Master thesis, 2022-06-01)Masteroppgåva har som formål å undersøkje om det er ein potensiell samanheng mellom observerte holocene skredhendingar og jordskjelv eller om det er tsunami, i Sulafjorden og i innsjøsedimenter på Hareidlandet. Problemstillinga ... -
Interpretation of alluvial deposits in deep directional resistivity data: the Triassic Skagerrak Formation, Ivar Aasen, Utsira High
(Master thesis, 2022-06-01)A significant amount of hydrocarbons are contained within fluvial deposits, which constitute potential CO2 storage sites. The Skagerrak 2 reservoir zone of the Triassic Skagerrak Formation in the Ivar Aasen field (North ... -
Processing and interpretation of reflection seismic data from Isfjorden, Svalbard
(Master thesis, 2022-06-01)The geology of the present-day Svalbard is complex and has formed through several million years of repeated episodes of orogeneses, uplift, deformation and erosion. This has resulted in complex deformation structures and ... -
Evolution of ore-forming fluids in a post-collisional porphyry Cu-Au system: A case study from the Bučim deposit, Republic of North Macedonia
(Journal article; Peer reviewed, 2022)The Bučim porphyry Cu-Au deposit is situated in the westernmost part of the Serbo-Macedonian Massif, Republic of North Macedonia. The deposit is hosted by Precambrian gneisses with tectonically imbedded rare lenses of ... -
Elastic Imaging and Full Waveform Inversion for Carbon Sequestration
(Master thesis, 2022-06-01)Geological sequestration of carbon dioxide (CO2) is essential to reduce the effects of global warming. However, this requires careful monitoring. Reflection seismics collects data from a large area and is therefore the ... -
Impact of runoff temporal distribution on ice dynamics
(Journal article; Peer reviewed, 2022)Record highs of meltwater production at the surface of the Greenland ice sheet have been recorded with a high recurrence over the last decades. Those melt seasons with longer durations, larger intensities, or with both ... -
Skredkartlegging og 10Be-eksponeringsdatering av fjellskred i Bondhusdalen, Kvinnherad kommune
(Master thesis, 2022-06-01)I Norge er skred den naturfaren som tar flest menneskeliv. Skred er en landskapsendrende prosess, med hurtige massebevegelser av bergartsfragmenter, løsmasser, vann og snø. Ulike skredprosesser avsetter landformer og ... -
Last interglacial sea-level proxies in the glaciated Northern Hemisphere
(Journal article; Peer reviewed, 2022)Because global sea level during the last interglacial (LIG; 130–115 ka) was higher than today, the LIG is a useful approximate analogue for improving predictions of future sea-level rise. Here, we synthesize sea-level ... -
Sources of uncertainty in Greenland surface mass balance in the 21st century
(Journal article; Peer reviewed, 2022)The surface mass balance (SMB) of the Greenland ice sheet is subject to considerable uncertainties that complicate predictions of sea level rise caused by climate change. We examine the SMB of the Greenland ice sheet in ... -
Temperature exposure in cod driven by changes in abundance
(Journal article; Peer reviewed, 2022)Animals actively select the most suitable habitat in terms of fitness, much of which is mediated by temperature. We reconstructed population abundance, oxygen isotope and temperature chronologies for the Icelandic and the ... -
Surface mass balance modeling of the Greenland ice sheet : Sensitivity and uncertainty of the energy balance model BESSI
(Doctoral thesis, 2022-06-17)The surface mass balance is the main connection between the atmospheric climate change and the evolution of Greenland ice sheet over the next century. This thesis focuses on the development of surface mass and energy balance ... -
Radiation damage allows identification of truly inherited zircon
(Journal article; Peer reviewed, 2022)Many studies have reported U-Pb dates of zircon that are older than the igneous rocks that contain them, and they are therefore thought to be inherited from older rock complexes. Their presence has profound geodynamic ... -
Investigating multiple sulfur isotope variations in active hydrothermal chimneys and fluids from the Arctic Mid Ocean Ridges
(Master thesis, 2022-05-09)The four different vent fields Seven Sisters, Soria Moria, Fåvne and Loki’s Castle are all located on the ultra-slow spreading AMOR. The Seven Sisters and the Soria Moria vent fields are located on the southern part of the ... -
The role of ocean and atmospheric dynamics in the marine-based collapse of the last Eurasian Ice Sheet
(Journal article; Peer reviewed, 2022)Information from former ice sheets may provide important context for understanding the response of today’s ice sheets to forcing mechanisms. Here we present a reconstruction of the last deglaciation of marine sectors of ... -
Tsunami risk communication and management: Contemporary gaps and challenges
(Journal article; Peer reviewed, 2022)Very large tsunamis are associated with low probabilities of occurrence. In many parts of the world, these events have usually occurred in a distant time in the past. As a result, there is low risk perception and a lack ... -
Monitoring glacial lake outburst flood susceptibility using Sentinel-1 SAR data, Google Earth Engine, and persistent scatterer interferometry
(Journal article; Peer reviewed, 2022)Continuous monitoring of glacial lakes, their parent glaciers and their surroundings is crucial because possible outbursts of these lakes pose a serious hazard to downstream areas. Ongoing climate change increases the risk ...
