Assessing linkages between ice sheet calving, subpolar gyre hydrography and deep water ventilation during the last glaciation
(Master thesis, 2017-06-23)It is commonly postulated that ice sheet dynamics and freshwater perturbations in the North Atlantic were linked to disruptions in deep water circulation and North Atlantic cooling in the past. However, the exact nature ... -
Assessment of CO2 storage capacity based on sparse data: Skade Formation
(Peer reviewed; Journal article, 2018-12)Large North Sea aquifers of high quality are the likely major target for 12 Gt of European CO2 emissions that should be stored in the subsurface by 2050. This involves an upscaling of the present combined injection rate ... -
An Assessment of Geophysical Survey Techniques for Characterising the Subsurface Around Glacier Margins, and Recommendations for Future Applications
(Journal article; Peer reviewed, 2022)Geophysical surveys provide an efficient and non-invasive means of studying subsurface conditions in numerous sedimentary settings. In this study, we explore the application of three geophysical methods to a proglacial ... -
Asynchronous Antarctic and Greenland ice-volume contributions to the last interglacial sea-level highstand
(Peer reviewed; Journal article, 2019-11-06)The last interglacial (LIG; ~130 to ~118 thousand years ago, ka) was the last time global sea level rose well above the present level. Greenland Ice Sheet (GrIS) contributions were insufficient to explain the highstand, ... -
Atlantic circulation changes across a stadial-interstadial transition
(Journal article; Peer reviewed, 2023)We combine consistently dated benthic carbon isotopic records distributed over the entire Atlantic Ocean with numerical simulations performed by a glacial configuration of the Norwegian Earth System Model with active ocean ... -
Atlantic inflow and low sea-ice cover in the Nordic Seas promoted Fennoscandian Ice Sheet growth during the Last Glacial Maximum
(Journal article; Peer reviewed, 2023)The Atlantic water inflow into the Nordic Seas has proven difficult to reconstruct for the Last Glacial Maximum. At that time, the Fennoscandian Ice Sheet grew potentially to its maximum extent. Sea-ice free conditions in ... -
Atlantic Ocean thermohaline circulation changes on orbital to suborbital timescales during the mid-Pleistocene
(Peer reviewed; Journal article, 2003-02-19)Mid-Pleistocene benthic ∂18O and ∂13C time series from the North Atlantic site 983 and Ceara Rise site 928 are compared to an array of existing isotopic records spanning the Atlantic basin and the geographic extremes of ... -
Atmosphere-driven ice sheet mass loss paced by topography: Insights from modelling the south-western Scandinavian Ice Sheet
(Peer reviewed; Journal article, 2018-09)Marine-terminating glaciers and ice streams are important controls of ice sheet mass balance. However, understanding of their long-term response to external forcing is limited by relatively short observational records of ... -
Atmospheric circulation over Europe during the Younger Dryas
(Journal article; Peer reviewed, 2020)The Younger Dryas (YD) was a period of rapid climate cooling that occurred at the end of the last glaciation. Here, we present the first palaeoglacier-derived reconstruction of YD precipitation across Europe, determined ... -
Axial and transverse deep‐water sediment supply to syn‐rift fault terraces: Insights from the West Xylokastro Fault Block, Gulf of Corinth, Greece
(Peer reviewed; Journal article, 2019)Deep‐water syn‐rift systems develop in partially‐ or transiently‐linked depocentres to form complicated depositional architectures, which are characterised by short transport distances, coarse grain sizes and a wide range ... -
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 ... -

(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 ... -
