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 ... -
Arctic sediment routing during the Triassic: sinking the Arctic Atlantis
(Journal article; Peer reviewed, 2022)Opening of the Arctic Ocean has been the subject of much debate, and the placement of terranes in the Early Mesozoic remains a crucial part of this important discussion. Several continental terranes complicate the ... -
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 ... -
Assessing rock glaciers for their hydrological significance in the Semi-arid Andes, Chile
(Master thesis, 2024-08-05)Rock glacier plays an important hydrological role in the semi-arid Chilean Andes, acting as buffers against water scarcity in a warming climate. This role will become more significant in the future since the glaciers in ... -
Assessing the influence of supraglacial lakes to the mass balance of Tapado Glacier
(Master thesis, 2023-11-27)Glaciers are an important source of water for agriculture, mining and large population residing in downstream basins in the semiarid Andes. The Tapado Complex (2.44 km2) is the main glacier in the catchment Coquimbo-La ... -
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 ... -
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 ... -
