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 ... -
Orogenesis from bottom to top – Investigating the geodynamics of mountain building using coupled thermo-mechanical-surface-process models
(Doctoral thesis, 2021-03-10)The objective of this project is to The objective of this project is to advance our understanding of mountain building processes in different plate tectonic settings and with specific focus on the interaction between surface ... -
Geochemical characteristics of volcanogenic massive sulfide mineralizations on Bømlo and Stord islands, Sunnhordaland, SW Norway
(Master thesis, 2021-09-11)The results from the present study have brought forward new knowledge about geochemical, mineralogical, stable isotope and trace element data for volcanogenic massive sulfide deposits hosted within Early Ordovician Ophiolitic ... -
Geochemical characteristics of the gold-bearing quartz veins in the Lykling area, Bømlo, SW Norway
(Master thesis, 2021-09-11) -
Sedimentary ancient DNA shows terrestrial plant richness continuously increased over the Holocene in northern Fennoscandia
(Journal article; Peer reviewed, 2021)The effects of climate change on species richness are debated but can be informed by the past. Here, we generated a sedimentary ancient DNA dataset covering 10 lakes and applied novel methods for data harmonization. We ... -
Sedimentary response to tectonism and rifting in basins on the Norwegian shelf and onshore Norway
(Doctoral thesis, 2021-09-10)The Norwegian sedimentary basins offshore and onshore have in variable degree been influenced by tectonism as rifting and faulting during deposition. This stems from post Caledonian extensional events that affected both ... -
Large-scale features of Last Interglacial climate: results from evaluating the lig127k simulations for the Coupled Model Intercomparison Project (CMIP6)–Paleoclimate Modeling Intercomparison Project (PMIP4)
(Journal article; Peer reviewed, 2021)The modeling of paleoclimate, using physically based tools, is increasingly seen as a strong out-of-sample test of the models that are used for the projection of future climate changes. New to the Coupled Model Intercomparison ... -
Paleokarst reservoir modelling - A concept-driven approach
(Doctoral thesis, 2021-08-20)A significant proportion of the world's hydrocarbon production comes from paleokarst reservoirs. Although these reservoirs boast some of the most productive wells in oil history, the recovery factor is relatively low ... -
Seasonal sea ice persisted through the Holocene Thermal Maximum at 80°N
(Journal article; Peer reviewed, 2021)The cryospheric response to climatic warming responsible for recent Arctic sea ice decline can be elucidated using marine geological archives which offer an important long-term perspective. The Holocene Thermal Maximum, ... -
Sea ice thickness from air-coupled flexural waves
(Journal article; Peer reviewed, 2021)Air-coupled flexural waves (ACFWs) appear as wave trains of constant frequency that arrive in advance of the direct air wave from an impulsive source travelling over a floating ice sheet. The frequency of these waves varies ... -
Late Holocene canyon-carving floods in northern Iceland were smaller than previously reported
(Journal article; Peer reviewed, 2021)Catastrophic floods have formed deep bedrock canyons on Earth, but the relationship between peak discharge and bedrock erosion is not clearly understood. This hinders efforts to use geological evidence of these cataclysmic ... -
Cold spells in the Nordic Seas during the early Eocene Greenhouse
(Journal article; Peer reviewed, 2020)The early Eocene (c. 56 - 48 million years ago) experienced some of the highest global temperatures in Earth’s history since the Mesozoic, with no polar ice. Reports of contradictory ice-rafted erratics and cold water ... -
Frictional properties and microstructural evolution of dry and wet calcite-dolomite gouges
(Journal article; Peer reviewed, 2021)Calcite and dolomite are the two most common minerals in carbonate-bearing faults and shear zones. Motivated by observations of exhumed seismogenic faults in the Italian Central Apennines, we used a rotary-shear apparatus ... -
Abiotic synthesis of methane and organic compounds in Earth’s lithosphere
(Journal article; Peer reviewed, 2020)Accumulation of molecular hydrogen in geologic systems can create conditions energetically favorable to transform inorganic carbon into methane and other organic compounds. Although hydrocarbons with a potentially abiotic ... -
Earthquake statistics changed by typhoon-driven erosion
(Journal article; Peer reviewed, 2020)Tectonics and climate-driven surface processes govern the evolution of Earth’s surface topography. Topographic change in turn influences lithospheric deformation, but the elementary scale at which this feedback can be ... -
Growth of collisional orogens from small and cold to large and hot ‐ inferences from geodynamic models
(Journal article; Peer reviewed, 2021)It is well documented that the interplay between crustal thickening and surface processes determines growth of continent-continent collision orogens from small and cold to large and hot. Additionally, studies have demonstrated ... -
Basement highs: definitions, characterisation and origins
(Journal article; Peer reviewed, 2020)A glossary of commonly used terms related to the geometric forms and geological settings of basement highs is presented to assist cross-disciplinary understanding, qualifying prefixes for the term basement are discussed ... -
Sedimentary anatomy and hydrological record of relic fluvial deposits in a karst cave conduit
(Journal article; Peer reviewed, 2021)This case study from the renowned Demänová Cave System in the Carpathians of Slovakia demonstrates that the conventional methods of fluvial sedimentology, combined with an allostratigraphic mapping and speleothem U-series ... -
Citizen Seismology in the Arctic
(Journal article; Peer reviewed, 2020)Landslides, earthquakes and other natural disasters are expected to increase in the Arctic, yet our ability to make informed decisions about safety is tightly limited by lack of data. As part of the Integrated Arctic ... -
Disentangling source of moisture driving glacier dynamics and identification of 8.2 ka event: evidence from pore water isotopes, Western Himalaya
(Journal article; Peer reviewed, 2020)Two atmospheric circulation patterns, the Indian Summer Monsoon (ISM) and mid-latitude Westerlies control precipitation and thus glacier variability in the Himalaya. However, the role of the ISM and westerlies in controlling ...
