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 ... -
Automated characterisation of Deep-sea imagery using Machine Learning: implications for future conservation and mineral extraction
(Master thesis, 2023-06-01)This thesis aimed to develop a methodology using Machine Learning (ML) techniques for the interpretation of deep-sea resources. The deep-sea hosts diverse ecosystems and valuable resources, but potential environmental ... -
Avalanches, climate and glaciers - a reconstruction based on lake sediments from lake Kjøsnesfjorden
(Master thesis, 2023-03-20)To kjerneprøver fra Kjøsnesfjorden, Vestland, har blitt analysert for å undersøke den glasiale historien og massebevegelser i holocen. Tidligere undersøkelser, klimatiske data og et kvartærgeologisk kart ble brukt for å ... -
AVO Inversion using Data Assimilation

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. ... -
Biogeochemical impact of historical submarine mine tailings on benthic ecosystems in the Repparfjord (Northern Norway)
(Journal article; Peer reviewed, 2024)Historical copper mine tailings deposited in the Repparfjord, Northern Norway, provided new insight into the biogeochemical impact of submarine tailings disposals on high-latitude coastal ecosystems. The submarine tailings ... -
Biomineralisering i kalde grotter: eksempler fra Nordland
(Master thesis, 2019-06-26)Samhandlingen mellom biologi og geologi i grotter er fortsatt lite forstått. Dette gjelder spesielt for biomineralisering; prosessen der mikroorganismer danner mineraler. Med bakgrunn i dette er det i denne oppgaven ... -
BLOKKHAV PÅ FJELLTOPPER PÅ YTRE SUNNMØRE OG LANGS INDRE ROMSDALSFJORDEN
(Master thesis, 2022-03-07)Åtte blokkhavsdekkede topper på ytre Sunnmøre og langs indre Romsdalsfjorden viser varierende overflatekarakteristikk og en stor spredning i 10Be-aldre. Aldrene strekker seg fra 15 ± 1 ka til 151 ± 2 ka, uten noen tydelige ... -
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 ... -
