Tracing the last remnants of the Scandinavian Ice Sheet: Ice-dammed lakes and a catastrophic outburst flood in northern Sweden
(Peer reviewed; Journal article, 2019-08-08)We present geomorphological evidence of large, previously undocumented, early Holocene ice-dammed lakes in the Scandinavian Mountains of northwestern Sweden. The lakes extents indicate that the last remnants of the ... -
Tracing the Sveconorwegian orogen into the Caledonides of West Norway: Geochronological and isotopic studies on magmatism and migmatization
(Journal article; Peer reviewed, 2021)The Sveconorwegian orogen represents a branch of Grenville-age (~1250–950 Ma) orogenic belts that formed during the construction of the supercontinent Rodinia. This study traces the Sveconorwegian records from its type-area ... -
Transfer entropy computation using the Perron-Frobenius operator
(Peer reviewed; Journal article, 2019)We propose a method for computing the transfer entropy between time series using Ulam's approximation of the Perron-Frobenius (transfer) operator associated with the map generating the dynamics. Our method differs from ... -
Transgressive development of coal-bearing coastal plain to shallow marine setting in a flexural compressional basin, Paleocene, Svalbard, Arctic Norway
(Doctoral thesis, 2008-09-08)The most extensive Paleogene succession on Svalbard, in the Arctic north of Norway, is found in the Central Tertiary Basin of Spitsbergen. It consists of a clastic basin fill of mudstone, sandstone, coal and rare conglomerate ... -
Transient Deep Ocean Cooling in the Eastern Equatorial Pacific Ocean at the Eocene-Oligocene Transition
(Journal article; Peer reviewed, 2023)At the Eocene-Oligocene Transition (EOT), approximately 34 million years ago, Earth abruptly transitioned to a climate state sufficiently cool for Antarctica to sustain large ice sheets for the first time in tens to hundreds ... -
Transient Increase in Arctic Deep-Water Formation and Ocean Circulation under Sea Ice Retreat
(Journal article; Peer reviewed, 2021)While a rapid sea ice retreat in the Arctic has become ubiquitous, the potential weakening of the Atlantic meridional overturning circulation (AMOC) in response to global warming is still under debate. As deep mixing occurs ... -
Transient landscape and stratigraphic responses to drainage integration in the actively extending central Italian Apennines
(Journal article; Peer reviewed, 2020)Drainage networks in continental rifts are generally reported as dynamic features that produce transitions between endorheic and exorheic conditions. While this is of major importance for landscape development, sediment ... -
Transient thermal effects in sedimentary basins with normal faults and magmatic sill intrusions - a sensitivity study
(Journal article; Peer reviewed, 2019-04-05)Magmatic intrusions affect the basin temperature in their vicinity. Faulting and physical properties of the basin may influence the magnitudes of their thermal effects and the potential source rock maturation. We present ... -
Transition from Late-Miocene syn-orogenic extension to Plio-Pleistocene Corinth Rifting in the Southern Hellenides, Northern Peloponnese, Greece
(Journal article; Peer reviewed, 2024)This study investigates the Late Miocene to Pliocene transition from contractional to extensional tectonics in the upper plate of the Western Aegean retreating subduction system focusing on the Northern Peloponnese area, ... -
Transition metal isotope fractionation in marine hydrothermal deposits of the Mohns Ridge, North Atlantic Ocean
(Doctoral thesis, 2012-08-24)Seafloor hydrothermal vent systems form along mid-ocean ridges in all of the Earth’s oceans. They have a major impact on the chemical exchange between the lithosphere and the hydrosphere, as vast volumes of seawater cycle ... -
Transnational Access to Research Facilities: an EPOS service to promote multi-domain Solid Earth Sciences in Europe
(Journal article; Peer reviewed, 2022)Transnational access (TNA) allows cross-border, short-term and frequently free-of-charge access to world-class research facilities, to foster collaborations and exchanges of experience. Specifically, TNA aims to encourage ... -
Transport of mafic magma through the crust and sedimentary basins: Jameson Land, East Greenland
(Journal article; Peer reviewed, 2021)Igneous sheet-complexes transport magma through the crust, but most studies have focused on single segments of the magma transport system or have low resolution. In the Jameson Land Basin in East Greenland, seismic reflection ... -
Traveltime approximation for strongly anisotropic media using the homotopy analysis method
(Peer reviewed; Journal article, 2019)Traveltime approximation plays an important role in seismic data processing, for example, anisotropic parameter estimation and seismic imaging. By exploiting seismic traveltimes, it is possible to improve the accuracy of ... -
Tredimensjonal gravimetrisk modellering på Vøring marginen
(Master thesis, 2008-06-02)En tredimensjonal litosfæremodell ble konstruert for Vøring marginen, utenfor kysten av Midt-Norge. Grunnlaget for modellen var 32 tolkede OBS-profiler. 11 regionale grenseflater ble digitalisert fra hvert av de 32 ... -
Trigger mechanisms for sand intrusions. Inferences from published data and investigation of 3D seismic data from the northern North Sea
(Master thesis, 2018-04-17)Numerous publications have addressed subsurface sediment remobilization, in terms of geometries of the intrusions, where the intrusions occur, the parent unit of the intrusions and trigger mechanisms. Several authors have ... -
Tropical temperature variations during the last glacial cycle from stalagmite fluid inclusions
(Master thesis, 2024-06-03)Low latitudes play a key role in the Earth's climate system, receiving the highest amount of solar energy that is redistributed across the globe through atmospheric and oceanic circulation. The MIS 5a – 4 boundary, ... -
Tsunami risk communication and management: Contemporary gaps and challenges
(Journal article; Peer reviewed, 2022)Very large tsunamis are associated with low probabilities of occurrence. In many parts of the world, these events have usually occurred in a distant time in the past. As a result, there is low risk perception and a lack ... -
