Architecture, deformation style and petrophysical properties of growth fault systems: the Late Triassic deltaic succession of southern Edgeøya (East Svalbard)
(Peer reviewed; Journal article, 2018-05-07)The Late Triassic outcrops on southern Edgeøya, East Svalbard, allow a multiscale study of syn‐sedimentary listric growth faults located in the prodelta region of a regional prograding system. At least three hierarchical ... -
Arctic Holocene proxy climate database – New approaches to assessing geochronological accuracy and encoding climate variables
(Peer reviewed; Journal article, 2014-08-29)We present a systematic compilation of previously published Holocene proxy climate records from the Arctic. We identified 170 sites from north of 58° N latitude where proxy time series extend back at least to 6 cal ka (all ... -
Arctic hydroclimate variability during the last 2000 years: Current understanding and research challenges
(Peer reviewed; Journal article, 2018-04-10)Reanalysis data show an increasing trend in Arctic precipitation over the 20th century, but changes are not homogenous across seasons or space. The observed hydroclimate changes are expected to continue and possibly ... -
Assessing first-order BQART estimates for ancient source-to- sink mass budget calculations
(Journal article; Peer reviewed, 2021)Constraining the timing and volume of sediment dispersal in an ancient sedimentary system is vital to understand a basin's infill history. One preferred method for a first-order approximation of ancient sediment load ... -
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 ... -
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 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 ... -
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 ... -
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 ... -
