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 ... -
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 ... -
Interdistributary bayfills, Neslen Formation (Upper Cretaceous), Book Cliffs: Processes and controls
(Master thesis, 2021-06-01)The Campanian (Upper Cretaceous) Neslen Formation which crops out in the Book Cliffs, Utah (USA) has been the focus area for this study where 32 sedimentary logs have been collected to identify the sedimentary processes ... -
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, ... -
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 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 ... -
Inversion of seismic AVA data for porosity and saturation
(Master thesis, 2013-06-27)Rock physics serves as the link between reservoir parameters and the effective elastic reservoir properties, and Amplitude Variation with Angle (AVA) modelling serves as the link between elastic properties and reflection ... -
Inversion of Teleseismic Polarization Data for Crustal Velocities in Norway
(Master thesis, 2017-06-23)To characterize the crustal and upper mantle structure it is possible to perform a joint inversion of receiver functions and apparent S-velocities. The inversion is performed using a linearized weighted iterative least-squares ... -
Inversion of the Linear and Parabolic Radon Transform

Inversion of time-lapse seismic waveform data using integral equation methods
(Master thesis, 2018-06-20)Time-lapse seismic data are considered a valuable tool for monitoring hydrocarbon reservoirs. Since the changes in elastic parameters associated with production of hydrocarbons, or injection of CO2 into a reservoir, tend ... -
