An integrated geological characterization of marine ground conditions in the North Sea
(Doctoral thesis, 2023-11-30)Geologiske karakterisering av marine grunnforhold for ankre og fundamenter for vindturbinder store vindkraftverk til havs er et relativt nytt felt. Som sådan er etableringen av beste praksis for integrering av geologiske, ... -
An integrated geological characterization of the Mid-Pleistocene to Holocene geology of the Sørlige Nordsjø II offshore wind site, southern North Sea
(Journal article; Peer reviewed, 2024)Subsurface deposits in recently glaciated marine areas are highly heterogeneous, representing a range of glacial and postglacial environments and processes including glacitectonism, overconsolidation, fluvial and lacustrine ... -
Integrating Multidisciplinary Observations in Vent Environments (IMOVE): Decadal Progress in Deep-Sea Observatories at Hydrothermal Vents
(Journal article; Peer reviewed, 2022-05-13)The unique ecosystems and biodiversity associated with mid-ocean ridge (MOR) hydrothermal vent systems contrast sharply with surrounding deep-sea habitats, however both may be increasingly threatened by anthropogenic ... -
Integration of ground-based hyperspectral and lidar scanning in virtual outcrop geology
(Doctoral thesis, 2011-01-28)The potential to visualize and analyse geological outcrops in a 3D environment has made terrestrial laser scanning (TLS) a standard method in geological field studies. Lidar models can be integrated with high resolution ... -
Interaction between mantle-derived magma and lower arc crust: quantitative reactive melt flow modelling using STyx
(Peer reviewed; Journal article, 2018)The magmatic processes occurring in the lowermost arc crust play a major role in the evolution of mantle-wedge-derived melt. Geological evidence indicates that mantle-derived magmas and in-situ products of lower crust ... -
The interaction between sea ice and salinity-dominated ocean circulation: implications for halocline stability and rapid changes of sea ice cover
(Peer reviewed; Journal article, 2016-11)Changes in the sea ice cover of the Nordic Seas have been proposed to play a key role for the dramatic temperature excursions associated with the Dansgaard–Oeschger events during the last glacial. In this study, we develop ... -
Interaction of igneous sills and host rocks of the Curtis Formation, Eastern Utah
(Master thesis, 2023-08-10) -
The interactions of volcanism and clastic sedimentation in rift basins: Insights from the Palaeogene-Neogene Shaleitian uplift and surrounding sub-basins, Bohai Bay Basin, China
(Journal article; Peer reviewed, 2021)Although volcanism is an important process in the evolution of rift basins, current tectono-sedimentary models largely neglect its impact on sediment supply, transport pathways, and depositional systems. In this paper, we ... -
InterCarb: A Community Effort to Improve Interlaboratory Standardization of the Carbonate Clumped Isotope Thermometer Using Carbonate Standards
(Journal article; Peer reviewed, 2021)Increased use and improved methodology of carbonate clumped isotope thermometry has greatly enhanced our ability to interrogate a suite of Earth-system processes. However, interlaboratory discrepancies in quantifying ... -
Internal Ocean Dynamics Control the Long-Term Evolution of Weddell Sea Polynya Activity
(Journal article; Peer reviewed, 2021)Open-ocean polynyas effectively couple the ocean and atmosphere through large ice-free areas within the sea-ice cover, release vast quantities of oceanic heat, and impact deep ocean ventilation. Changes in polynya activity, ... -
Internal structure of a Himalayan debris-covered glacier revealed by borehole optical televiewing
(Journal article; Peer reviewed, 2023)Characterising the structures within glaciers can give unique insight into ice motion processes. On debris-covered glaciers, traditional structural glaciological mapping is challenging because the lower glacier is hidden ... -
An international intercomparison of stable carbon isotope composition measurements of dissolved inorganic carbon in seawater
(Peer reviewed; Journal article, 2019)We report results of an intercomparison of stable carbon isotope ratio measurements in seawater dissolved inorganic carbon (δ 13C‐DIC) which involved 16 participating laboratories from various parts of the world. The ... -
The interplay between surface processes and tectonics in the actively extending central Italian Apennines
(Doctoral thesis, 2020-06-08)The overall objective of this project is to improve our understanding of the interplay between surface processes and tectonics in active continental rifts, based on the central part of the Italian Apennines. Three key ... -
Interpretation of 3D Ground Penetrating Radar data in archaeology by applying seismic attributes
(Master thesis, 2023-11-20)Ground Penetrating Radar (GPR) has emerged as a widely employed geophysical method in archaeological studies, with recent advancements leading to large-scale, high-resolution surveys. The processing techniques applied to ... -
Interpretation of alluvial deposits in deep directional resistivity data: the Triassic Skagerrak Formation, Ivar Aasen, Utsira High
(Master thesis, 2022-06-01)A significant amount of hydrocarbons are contained within fluvial deposits, which constitute potential CO2 storage sites. The Skagerrak 2 reservoir zone of the Triassic Skagerrak Formation in the Ivar Aasen field (North ... -
Interpreting archaeological site-formation processes at a mountain ice patch: A case study from Langfonne, Norway
(Journal article; Peer reviewed, 2021)In the context of global warming, ice patches are increasingly important foci of high-elevation archaeology. Langfonne in Jotunheimen, central southern Norway, is uniquely suited to provide a window onto site formation ... -
Intraplate Earthquakes in Nordland, Northern Norway : Insight from Seismic Tomography and Earthquake Analysis
(Doctoral thesis, 2023-01-19)Intraplate-seismisitet refererer til jordskjelv i områder som ikke er påvirket av prosessene langs aktive plategrenser. Det totale seismiske momentet utløst fra intraplatejordskjelv er mye mindre enn fra jordskjelv i ... -
