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 ... -
Outcrop-scale fracture analysis and seismic modelling of a basin-bounding normal fault in platform carbonates, central Italy
(Journal article; Peer reviewed, 2022)Faults are characterized by a complex internal architecture. In carbonates, the geometry, attitude, and distribution of fault-related fractures and subsidiary faults can largely affect the petrophysical properties and hy ... -
Estimating the volume of the 1978 Rissa quick clay landslide in Central Norway using historical aerial imagery
(Journal article; Peer reviewed, 2022)Quick clay is found across Scandinavia and is especially prominent in south-eastern and central Norway. Quick clay is prone to failure and can cause landslides with high velocities and large run-outs. The 1978 Rissa landslide ... -
Structural reconstructions of the Eastern Barents Sea at Meso-Tertiary evolution and influence on petroleum potential
(Journal article; Peer reviewed, 2021)Barents Sea basin is the most explored and studied by the regional and petroleum geologists on the Russian Arctic shelf and has approved gas reserves. However, there are many questions in the petroleum exploration, one of ... -
Compositions of dissolved organic matter in the ice-covered waters above the Aurora hydrothermal vent system, Gakkel Ridge, Arctic Ocean
(Journal article; Peer reviewed, 2022)Hydrothermal vents modify and displace subsurface dissolved organic matter (DOM) into the ocean. Once in the ocean, this DOM is transported together with elements, particles, dissolved gases and biomass along with the ... -
The Volcanic Hazards of Jan Mayen Island (North-Atlantic)
(Journal article; Peer reviewed, 2022)Hazard assessment of remote volcanic islands provides many challenges compared to other volcanoes and volcanic fields. Here we present the first systematic volcanic hazard assessment of Jan Mayen Island, a remote island ...
