Coupled stalagmite - Alluvial fan response to the 8.2ka event and early Holocene palaeoclimate change in Greece
(Peer reviewed; Journal article, 2019)We explore the expression of early Holocene climatic change in the terrestrial Mediterranean of southern Greece. A regional palaeoclimate record from stable isotope and trace element geochemical proxies in an early Holocene ... -
Coupled surface process and tectonic modelling of extension-inversion tectonics in the Pyrenees
(Doctoral thesis, 2014-09-26) -
Coupling Crustal-Scale Rift Architecture With Passive Margin Salt Tectonics: A Geodynamic Modeling Approach
(Journal article; Peer reviewed, 2022)Continental rifted margins are often associated with widespread, thick evaporite (i.e., salt) deposits and pronounced salt tectonics. The majority of salt basins formed during the latest stages of rifting, prior to continental ... -
Crevasses on Svalbard Glaciers: Distribution and Dynamic Controls
(Master thesis, 2015-05-31)Crevasses play a key role in understanding a wide range of glaciological processes, but the current understanding is mainly based on a few key studies. Recent years, studies on crevasse formation have been motivated by the ... -
Crustal domains in the Western Barents Sea
(Journal article; Peer reviewed, 2021)The crustal architecture of the Barents Sea is still enigmatic due to complex evolution during the Timanian and Caledonian orogeny events, further complicated by several rifting episodes. In this study we present the new ... -
Crustal structure across the western Barents Sea from deep seismic and potential field data. Implications for Caledonian trends and subsequent basin formation
(Doctoral thesis, 2018-05-24)The aim of this project is to map the deep crustal structure of the western Barents Sea in order to increase the understanding of how pre-existing structures related to the Caledonian orogeny and subsequent extensional ... -
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 ... -
