Basement highs: definitions, characterisation and origins
(Journal article; Peer reviewed, 2020)A glossary of commonly used terms related to the geometric forms and geological settings of basement highs is presented to assist cross-disciplinary understanding, qualifying prefixes for the term basement are discussed ... -
Basement structure and its influence on the structural configuration of the northern North Sea rift
(Peer reviewed; Journal article, 2017-06)The northern North Sea rift basin developed on a heterogeneous crust comprising structures inherited from the Caledonian orogeny and Devonian postorogenic extension. Integrating two‐dimensional regional seismic reflection ... -
Basin-scale architecture of deeply emplaced sill complexes: Jameson Land, East Greenland
(Peer reviewed; Journal article, 2016)Igneous sills are common components in rifted sedimentary basins globally. Much work has focused on intrusions emplaced at relatively shallow palaeodepths (0 – 1.5 km). However, owing to constraints of seismic reflection ... -
Be-10 Dating of Ice-Marginal Moraines in the Khumbu Valley, Nepal, Central Himalaya, Reveals the Response of Monsoon-Influenced Glaciers to Holocene Climate Change
(Journal article; Peer reviewed, 2022)The dynamic response of large mountain glaciers to climatic forcing operates over timescales of several centuries and therefore understanding how these glaciers change requires observations of their behavior through the ... -
Behaviourally modern humans in coastal southern Africa experienced an increasingly continental climate during the transition from Marine Isotope Stage 5 to 4
(Journal article; Peer reviewed, 2023-07-25)Unravelling evolution-by-environment interactions on the gut microbiome is particularly relevant considering the unprecedented level of human-driven disruption of the ecological and evolutionary trajectories of species. ... -
The brittle evolution of Western Norway – A space-time model based on fault mineralizations, K–Ar fault gouge dating and paleostress analysis
(Journal article; Peer reviewed, 2022)Basement fracture and fault patterns on passive continental margins control the onshore landscape and offshore distribution of sediment packages and fluid pathways. In this study, we decipher the spatial-temporal evolution ... -
Bruddsystem og spenningsfelt tilknyttet tunneltraséen Ringveg Vest i Bergen
(Master thesis, 2003)Denne hovedfagsoppgaven er en del av forundersøkelsene som er utført i sammenheng med tunnelprosjektet Ringveg Vest i Bergen kommune, Hordaland, som har driftstart i 2005. Ringveg Vest er planlagt å ligge cirka 4 kilometer ... -
Bruk av borekaksmateriale fra letebrønner til studier av erosjon i kvartær.
(Master thesis, 2016-06-15)Naustformasjonen er en glasialt derivert avsetning dannet gjennom de siste 2,8 millioner år (Ma) på midtnorsk sokkel. Formasjonen, som består av fem enheter (Naust-N, -A, -U, -S og - T), består av mektige klinoformer som ... -
Building up or out? Disparate sequence architectures along an active rift margin-Corinth rift, Greece
(Peer reviewed; Journal article, 2017-12)Early Pleistocene synrift deltas developed along the southern Corinth rift margin were deposited in a single, dominantly lacustrine depocenter and were subject to the same climate-related base-level and sediment supply ... -
Buoyancy forcing: A key driver of northern North Atlantic sea surface temperature variability across multiple timescales
(Journal article; Peer reviewed, 2023)Analyses of observational data (from year 1870 AD) show that sea surface temperature (SST) anomalies along the pathway of Atlantic Water transport in the North Atlantic, the Norwegian Sea and the Iceland Sea are spatially ... -
Calendar year age estimates of Allerød - Younger Dryas sea-level oscillations at Os, western Norway
(Journal article, 2004)A detailed shoreline displacement curve documents the Younger Dryas transgression in western Norway. The relative sea-level rise was more than 9m in an area which subsequently experienced an emergence of almost 60 m. The ... -
Calibration of seismic and well data: Towards Improved Quantitative Seismic Reservoir Characterisation of the Triassic to Middle-Jurassic Gullfaks Reservoir Units of the northern North Sea
(Master thesis, 2011-11-20)Abstract: Characterization and evaluation of (oil and gas) reservoirs is typically achieved using a combination of seismic and well data. It is therefore critical that the two data types are well calibrated to correct and ... -
Calibration, validation and application of the foraminiferal Mg/Ca. Reconstructing the intermediate water masses structure and origin in the Western Tropical Atlantic
(Doctoral thesis, 2015-05-22)The Atlantic Meridional Overturning Circulation (AMOC) plays a central role in the northward distribution of heat. It is a key mechanism in the climatic system that needs to be further understood. Most studies focused on ... -
Cambrian (Series 3 - furongian) conodonts from the alum shale formation at Slemmestad, Oslo region, Norway
(Peer reviewed; Journal article, 2018-05-09)Nine samples from the Alum Shale of Slemmestad, Oslo Region, were processed for conodonts. The limestone-rich interval extending from the mid Cambrian Paradoxides paradoxissimus trilobite Zone to the Lower Ordovician ... -
Can we use ice sheet reconstructions to constrain meltwater for deglacial simulations?
(Peer reviewed; Journal article, 2012)Freshwater pulses from melting ice sheets are thought to be important for driving deglacial climate variability. This study investigates challenges in simulating and understanding deglacial climate evolution within this ... -
The Cascadia subduction zone: Kinky or not? An implementation of a 2D background velocity model in teleseismic scattered-wave inversion.
(Master thesis, 2017-06-23)This thesis, within the field of seismology, investigates the process and effect of implementing a complex reference model in a teleseismic migration technique based on the Inverse Generalized Radon Transform. This migration ... -
Case study of combined marine- and land-based passive seismic surveying in front of Nordenskiöldbreen outlet glacier, Adolfbukta, Svalbard
(Journal article; Peer reviewed, 2023)Glaciers generate seismic waves due to calving and fracturing, meaning that recording and following event classification can be used to monitor glacier dynamics. Our aim with this study is to analyse seismic data acquired ... -
Causality from palaeontological time series
(Peer reviewed; Journal article, 2018-07)As custodians of deep time, palaeontologists have an obligation to seek the causes and consequences of long‐term evolutionary trajectories and the processes of ecosystem assembly and collapse. Building explicit process ... -
