Tectono-thermal evolution and morphodynamics of the central dronning maud land mountains, east antarctica, based on new thermochronological data
(Peer reviewed; Journal article, 2018-10-26)The lack of preserved Mesozoic–Cenozoic sediments and structures in central Dronning Maud Land has so far limited our understanding of the post-Pan-African evolution of this important part of East Antarctica. In order to ... -
Tectonostratigraphic development of the Upper Triassic to Middle Jurassic in the Hoop Area, Barents Sea: Implications for understanding ultra-condensed reservoir units
(Journal article; Peer reviewed, 2022)The most prolific reservoir intervals in the Barents Sea are found in the Upper Triassic to Middle Jurassic Realgrunnen Subgroup, deposited during a major change in the structural evolution of the basin which greatly ... -
Tectonostratigraphic evolution of a multi-episodic rift. The northern Norway - Greenland rift: from post-orogenic exhumation to deep marine turbidites
(Doctoral thesis, 2015)The aim of this project is to improve the tectonostratigraphic understanding of the northern part of the Norwegian passive continental margin, the so-called Lofoten margin, and contribute to the wider understanding of ... -
Temperature controls carbon cycling and biological evolution in the ocean twilight zone
(Journal article; Peer reviewed, 2021)Theory suggests that the ocean’s biological carbon pump, the process by which organic matter is produced at the surface and transferred to the deep ocean, is sensitive to temperature because temperature controls photosynthesis ... -
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 ... -
Temperature sensitivity of the mineral permafrost feedback at the continental scale
(Journal article; Peer reviewed, 2024)Oxidative weathering of sulfide minerals in sedimentary rocks releases carbon dioxide (CO2) into the atmosphere. In permafrost zones, this could be a positive feedback on climate change if it increases with warming, yet ... -
Temperature variability within the upper water masses of the western tropical Atlantic during rapid climate transitions
(Master thesis, 2010-01-20)Rapid reorganization of the ocean circulation in the Atlantic Ocean has been linked to widespread varations in climate on both millennial and glacial-interglacial timescales. The response of the tropical Atlantic upper ... -
Temperature variation in caves and its significance for subterranean ecosystems
(Journal article; Peer reviewed, 2023)Climate change affects all ecosystems, but subterranean ecosystems are repeatedly neglected from political and public agendas. Cave habitats are home to unknown and endangered species, with low trait variability and intrinsic ... -
Tephra horizons identified in the western North Atlantic and Nordic Seas during the Last Glacial Period: Extending the marine tephra framework
(Journal article; Peer reviewed, 2020)Geochemically distinct volcanic ash (tephra) deposits are increasingly acknowledged as a key geochronological tool to synchronize independent paleoclimate archives. Recent advances in the detection of invisible (crypto) ... -
Tephrochronology of the North Atlantic during the Last Glacial period – a paleoclimate synchronization tool
(Doctoral thesis, 2021-04-09)During present time, the global climate is changing at a rapid pace. To understand the future consequences of these changes, studies of past abrupt climate change are essential. A natural analogue to the current climate ... -
Testing the Environmental Seismic Intensity Scale on Data Derived from the Earthquakes of 1626, 1759, 1819, and 1904 in Fennoscandia, Northern Europe
(Journal article; Peer reviewed, 2021)Earthquake environmental effects (EEEs) were compiled for the earthquakes of 1626, 1759, 1819, and 1904 in the Fennoscandian Peninsula, northern Europe. The principal source of information was the contemporary newspaper ... -
Textural and geochemical characteristics of hematitic chert deposits in SW Norway: Implications for formation settings and processes
(Master thesis, 2017-11-30)Jasper, a specific type of hematitic chert, is often interpreted as an ancient analogue to modern seafloor hydrothermal deposits. Modern low-temperature seafloor hydrothermal Fe-deposits are mainly produced by Fe(II)- ... -
The formation of the ophiolitic terrane of SW Norway - relationships between immature island arc volcanic sequences and trondhjemitic complexes on Bømlo
(Master thesis, 2021-10-01)Single zircon U/Pb dating, geochemistry, and field descriptions from trondhjemitic and tonalitic intrusions, intruding the Lykling Ophiolite Complex, provide new insights into the origin and evolution of the Early Ordovician ... -
THE GEOMETRY AND TOPOLOGY OF DEFORMATION BAND NETWORKS IN VOLCANICLASTIC ROCKS: A CASE STUDY FROM SHIHTIPING, SOUTH-EASTERN TAIWAN
(Master thesis, 2021-03-05)Deformation bands are tabular strain localization features, common in porous and granular rocks. These structures of millimeter to centimeter thickness can occur as single bands and develop into clusters or networks of ... -
The importance of mineralogy in the formation of polygonal fault systems in the North Sea
(Master thesis, 2023-06-01) -
The Molloy Oceanic Core Complex: Petrological Studies of Mantle Rocks
(Master thesis, 2024-06-03)Seafloor spreading at ultraslow spreading rates causes uplift of the underlying crustal structure and mantle, forming oceanic core complexes (OCC). At the edge of the perennial Arctic sea ice cover, the Fram Strait forms ... -
The propagation, interaction and linkage of vein segments and the scatter of geometric data
(Master thesis, 2019-06-28)The lengths, widths, orientations, bridge widths and linkage characteristics of 636 vein segments from 84 arrays have been measured and analysed. The relationships between the parameters are assessed. The veins are in the ... -
The spatial-temporal geomorphology of meandering river channels in distributive fluvial systems

The topographic evolution of post-Caledonian landscapes in the inner Nordfjord, SW-Norway | New insights from AFT dating and thermal history modelling
(Master thesis, 2021-08-24)The topographic evolution of the present-day mountains of western Norway is not completely resolved. Long after the breakup of the Caledonides, the mountains along the passive continental margin of Norway remain high, with ...
