Modelling of OBS Data Across the Vestbakken Volcanic Province
(Master thesis, 2011)A P-Wave model of a 384 km long Ocean Bottom Seismometer profile has been modelled by use of ray-tracing. The profile, Bear Island South (BIS-2008), crossses the transtensional Vestbakken Volcanic Province and the boundary ... -
A Modelling Workflow for Seismic Characterization of Paleokarst Reservoirs
(Master thesis, 2018-12-14)Karst is a type of landscape formed by dissolution of soluble rocks such as carbonates. Caves are common subsurface karst features and develop where water percolates through the host rock and creates cave-passages through ... -
The Moho Architecture and Its Role for Isostasy—Insights From the Lofoten-Vesterålen Rifted Margin, Norway
(Journal article; Peer reviewed, 2023)The crustal structure of the Nordland and Troms region, Norway, has received growing scientific attention because (a) the region is one of the most seismically active areas of mainland Norway, and (b) there are differing ... -
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 ... -
Morphology and life history divergence in cave and surface populations of Gammarus lacustris (L.)
(Peer reviewed; Journal article, 2018-10-25)Cave animals provide a unique opportunity to study contrasts in phenotype and life history in strikingly different environments when compared to surface populations, potentially related to natural selection. As such, we ... -
Morphotectonic Evolution of Passive Margins Undergoing Active Surface Processes: Large-Scale Experiments Using Numerical Models
(Journal article; Peer reviewed, 2020)Extension of the continental lithosphere can lead to the formation of rifted margins with contrasting tectonic and geomorphologic characteristics. Many of these characteristics depend on the manner extension spatially ... -
Morris Jesup Spur and Rise north of Greenland – exploring present seabed features, the history of sediment deposition, volcanism and tectonic deformation at a Late Cretaceous/early Cenozoic triple junction in the Arctic Ocean
(Journal article; Peer reviewed, 2021)The narrow Morris Jesup Spur and an adjacent broader western rise extend 220 km into the Eurasia Basin from the shelf edge north of Greenland. We have used a hovercraft platform drifting with the sea to collect the first ... -
Mountain Building or Backarc Extension in Ocean-Continent Subduction Systems: A Function of Backarc Lithospheric Strength and Absolute Plate Velocities
(Journal article; Peer reviewed, 2019)The crustal structure of overriding plates in subduction settings around the world varies between a wide range of deformation styles, ranging from extensional structures and backarc opening as in the Tonga or Hellenic ... -
Mudstone-rich fluvial systems as reservoirs: The Brushy Basin Member of the Morrison Formation, Eastern Utah
(Master thesis, 2018-09-27)Mudstone-rich fluvial systems are common in the sedimentary record, such as the Triassic of the Barents Sea, but have received little scientific attention compared to their sandstonerich counterparts. However, mudstone-rich ... -
A multi-model CMIP6-PMIP4 study of Arctic sea ice at 127 ka: sea ice data compilation and model differences
(Journal article; Peer reviewed, 2021)The Last Interglacial period (LIG) is a period with increased summer insolation at high northern latitudes, which results in strong changes in the terrestrial and marine cryosphere. Understanding the mechanisms for this ... -
A multi-nuclide approach to constrain landscape evolution and past erosion rates in previously glaciated terrains
(Peer reviewed; Journal article, 2015-10)Cosmogenic nuclides are typically used to either constrain an exposure age, a burial age, or an erosion rate. Constraining the landscape history and past erosion rates in previously glaciated terrains is, however, notoriously ... -
Multi-proxy evidence of unprecedented hydroclimatic change in a high Arctic proglacial lake: Linnévatnet, Svalbard
(Journal article; Peer reviewed, 2023)Svalbard is at the forefront of sea ice, marine, and terrestrial environmental change in the Arctic and so can be viewed as an example of what may be expected in other high latitude regions influenced by the North Atlantic ... -
Multi-proxy speleothem-based reconstruction of mid-MIS 3 climate in South Africa
(Journal article; Peer reviewed, 2023)The southern coast of South Africa displays a highly dynamical climate as it is at the convergence of the Atlantic and Indian oceans, and it is located near the subtropical/temperate zone boundary with seasonal influence ... -
Multidecadal changes in Iceland Scotland Overflow Water vigor over the last 600 years and its relationship to climate
(Peer reviewed; Journal article, 2016-03)Changes in the Atlantic Meridional Overturning Circulation (AMOC) have commonly been invoked to explain the low-frequency climate changes evident over millennial-multidecadal timescales during the Holocene period. While ... -
Multidimensional Multirate Sampling and Seismic Migration
(Master thesis, 2010-06-01)Seismic data are usually recorded in time and space on rectangular lattices. Seismic wave propagation is described by the wave-equation, which yields a Fourier spectrum with smaller bandwidth than the rectangular periodicity ... -
Multimode 3‐D Kirchhoff Migration of Receiver Functions at Continental Scale
(Journal article; Peer reviewed, 2019)Receiver function analysis is widely used to image sharp structures in the Earth, such as the Moho or transition zone discontinuities. Standard procedures either rely on the assumption that underlying discontinuities are ... -
National EPOS initiatives and participation to the EPOS integration plan
(Journal article; Peer reviewed, 2022)European Plate Observing System (EPOS) is designed on a three-level architecture. The national research infrastructures (NRIs) constitute the backbone of the EPOS delivery framework, where data are generated, processed, ... -
Nature and geodynamics of Grenville-age orogens in Norway and Dronning Maud Land (East Antarctica) during the assembly of Rodinia: insights into the lateral terminations of the greater Grenville Orogen
(Doctoral thesis, 2021-09-14)The Grenville Orogeny represents a globally pervasive tectonothermal event resulting in the amalgamation of the supercontinent Rodinia between ca. 1.3 and 1.0 Ga. The Grenville Orogen appears to be a continuous collisional ... -
Nature and origin of the cover sequence of the Tuscan basement on Elba Island: evidence from detrital zircon dating
(Master thesis, 2013)Elba Island represents the westernmost part of the northern Apennines and has, for the last decades, been a subject to comprehensive geological studies. Due to west-directed subduction of the Adriatic microplate below ... -
