Tectono-stratigraphic evolution of the El Qaa fault block, Sinai, Egypt - an ArcGIS and MOVE study
(Master thesis, 2015-06-01)The Gulf of Suez is a classic example of a failed rift system and due to the extensive erosion it has become perfect for studying structural style and stratigraphy in a 3D environment, where the sedimentary architecture ... -
Tectono-stratigraphic model for high-displacement crustal normal faults on continental rifts : The Late Jurassic and earliest Cretaceous on and around the Frøya High, Norwegian Sea
(Doctoral thesis, 2024-04-05)Nye seismiske refleksjonsdata og forbedringer i prosessering av seismikk i løpet av de siste to tiårene har forbedret muligheten for å se strukturer i necking- og distaldomenet i riftede marginer. Osmundsen og Peron-Pinvidic ... -
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 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 ... -
A theoretical approach to glacier equilibrium-line altitudes using meteorological data and glacier massbalance
(Peer reviewed; Journal article, 2003-05-01)Based on a close exponential relationship between mean ablation-season temperature and winter precipitation at the equilibrium-line altitude (ELA) of 10 Norwegian glaciers, three equations are derived. The first equation ... -
Theoretical equilibrium-line altitudes and glacier buildup sensitivity in southern Norway based on meteorological data in a geographical information system
(Peer reviewed; Journal article, 2003-05-01)Three equations derived from a close exponential glacier-climate relationship at the equilibrium-line altitude (ELA) of Norwegian glaciers have been utilized and implemented in a geographical information system (GIS). The ... -
Time-lapse techniques for surface velocity, front position and calving rate measurement of a fast-flowing tidewater glacier in Svalbard
(Master thesis, 2015-05-31)Calving is the mechanical loss of icebergs from tidewater glaciers, responsible for 70% of the annual transfer of mass from the cryosphere to the ocean (van der Veen 1998a, 2002). To be able to correctly predict future ... -
