Crustal structure and erosion of the Lofoten/Vesterålen shelf, northern Norwegian margin
(Journal article; Peer reviewed, 2020)The Norwegian continental shelf has been through several rift phases since the Caledonian orogeny. Early Cretaceous rifting created the largest sedimentary basins, and Early Cenozoic continental breakup between East Greenland ... -
Crustal structure and evolution of the Arctic Caledonides: Results fromcontrolled-source seismology
(Peer reviewed; Journal article, 2017-10)The continuation of the Caledonides into the Barents Sea has long been a subject of discussion, and two major orientations of the Caledonian deformation fronts have been suggested: NNW-SSE striking and NE-SW striking. A ... -
Crustal structure and intraplate seismicity in Nordland, Northern Norway: insight from seismic tomography
(Journal article; Peer reviewed, 2022)The Nordland region, Northern Norway, situated in an intraplate continental setting, has the highest seismicity rate in mainland Norway. However, the exact cause of seismicity in this region is still debated. Better ... -
Crustal structure and origin of the Eggvin Bank west of Jan Mayen, NE Atlantic
(Peer reviewed; Journal article, 2017-01)The Eggvin Bank, located between the Jan Mayen Island and Greenland, is an unusually shallow area containing several submarine volcanic peaks, confined by two transforms on the Northern Kolbeinsey Ridge (NKR). We represent ... -
Crustal structure and seismicity of Cuba and Web-based applications for earthquake analysis
(Doctoral thesis, 2002)This thesis comprises six papers divided into two parts. Part I consist of four papers in which a study of the crust and seismicity of Cuba is presented. The main achievements in this part are: (1) A new Pwave velocity ... -
The crustal structure in the Northwest Atlantic region from receiver function inversion – Implications for basin dynamics and magmatism
(Journal article; Peer reviewed, 2022)The Labrador Sea and Baffin Bay form an extinct Palaeogene oceanic spreading system, divided by a major continental transform, the Davis Strait, with the whole region defined as the Northwest Atlantic. The Davis Strait ... -
The crustal structure in the transition zone between the western and eastern Barents Sea
(Peer reviewed; Journal article, 2018-07)We present a crustal-scale seismic profile in the Barents Sea based on new data. Wide-angle seismic data were recorded along a 600 km long profile at 38 ocean bottom seismometer and 52 onshore station locations. The modelling ... -
Crustal structure of the ultra-slow spreading Knipovich Ridge, North Atlantic, along a presumed ridge segment center
(Peer reviewed; Journal article, 2010)A combined ocean bottom seismometer, multichannel seismic reflection and gravity study has been carried out along the spreading direction of the Knipovich Ridge over a topographic high that defines a segment center. The ... -
Crustal transect from the Knipovich Ridge to Bear Island across the western Barents Sea margin
(Master thesis, 2010-06-08)A crustal model of a 322 km long transect from the Knipovich Ridge to Bear Island (Bjørnøya) has been obtained by use of reflection seismic data and wide angle Ocean Bottom Seismometer (OBS) data. Further constraints of ... -
Crustal velocity-depth model from Barents Sea Southeast based on a SSW-NNE oriented OBS-profile transecting the Tiddlybanken Basin and the Bjarmeland Platform
(Master thesis, 2014-11-20)A crustal model transecting the Tiddlybanken Basin, Hjalmar Johansen High and Bjarmeland Platform in the Barents Sea Southeast have been constructed with emphasis on P-wave phase picking and subsequent P-wave model-building ... -
Cryostratigraphy and sedimentology of high-Arctic fjord-valleys
(Doctoral thesis, 2018-01-17)Fjord-valleys, as sediment-filled palaeofjords, are characteristic of formerly glaciated mountainous coastal areas. High-Arctic fjord-valleys commonly host permafrost, but are poorly accessible and hence have drawn relatively ... -
Cryostratigraphy, sedimentology, and the late Quaternary evolution of the Zackenberg River delta, northeast Greenland
(Peer reviewed; Journal article, 2017-05-30)The Zackenberg River delta is located in northeast Greenland (74°30′ N, 20°30′ E) at the outlet of the Zackenberg fjord valley. The fjord-valley fill consists of a series of terraced deltaic deposits (ca. 2 km2) formed ... -
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 ... -
Dansgaard-Oeschger and Heinrich event temperature anomalies in the North Atlantic set by sea ice, frontal position and thermocline structure
(Journal article; Peer reviewed, 2022)We use eighteen timescale-synchronised near-surface temperature reconstructions spanning 10–50 thousand years before present to clarify the regional expression of Dansgaard-Oeschger (D-O) and Heinrich (H) events in the ... -
Dansgaard-Oeschger cycles: Interactions between ocean and sea ice intrinsic to the Nordic seas
(Peer reviewed; Journal article, 2013-09)Dansgaard-Oeschger (D-O) cycles are the most dramatic, frequent, and wide-reaching abrupt climate changes in the geologic record. On Greenland, D-O cycles are characterized by an abrupt warming of 10 ± 5°C from a cold ... -
Dansgaard–Oeschger events in climate models: review and baseline Marine Isotope Stage 3 (MIS3) protocol
(Journal article; Peer reviewed, 2023)Dansgaard–Oeschger (D–O) events, millennial-scale climate oscillations between stadial and interstadial conditions (of up to 10–15 ∘C in amplitude at high northern latitudes), occurred throughout the Marine Isotope Stage ... -
Data integration and FAIR data management in Solid Earth Science
(Journal article; Peer reviewed, 2022)Integrated use of multidisciplinary data is nowadays a recognized trend in scientific research, in particular in the domain of solid Earth science where the understanding of a physical process is improved and made complete ... -
