Anatomy and allostratigraphy of deep-marine Mount Messenger Formation (Miocene), eastern-margin Taranaki Basin, New Zealand
(Master thesis, 2003)Purpose of study: Sedimentological description of outcropping deep-water clastics within Mount Messenger Formation. Study area: North-Taranaki coastal region, North Island, New Zealand. Methodology: Mapping on foot and ... -
Anisotropic Properties of a Mid-Lithospheric Discontinuity in eastern North America
(Master thesis, 2017-06-23)During the last few years the occurrence of a mid-lithospheric discontinuity (MLD) has been observed in lithospheric studies of cratons. Studies using receiver functions have focused mainly on extracting high resolution ... -
Antropogen påvirkning og bæreevne i turistgrotter: Grønligrotta, Mo i Rana
(Master thesis, 2018-06-20)Grønligrotta er den eneste turistgrotta i Norge med innlagt belysning og god tilrettelegging for turister. Hensikten med denne masteroppgaven har vært å undersøke hvordan turistene påvirker miljøet i grotta, og om dette ... -
Application of Clumped Isotope Thermometry to Benthic Foraminifera
(Peer reviewed; Journal article, 2019-04)Obtaining absolute temperatures of the ocean in deep time is complicated by the lack of constraints on seawater chemistry. Seawater salinity, carbonate ion concentration, δ18O, and elemental abundance changes may obscure ... -
Applied Structural Geology – Case Studies of Underground Constructions and Rockslides
(Doctoral thesis, 2008-02-26)An understanding of the structural elements in the sub-surface is of great importance when establishing new constructions in bedrock, or surveying areas prone to rockslides. In this thesis the focus has been on combining ... -
Architecture of growth basins in a tidally influenced, prodelta to delta-front setting: The Triassic succession of Kvalpynten, East Svalbard
(Peer reviewed; Journal article, 2019)World‐class examples of fault‐controlled growth basins with associated syn‐kinematic sedimentary fill are developed in Upper Triassic prodelta to delta‐front deposits exposed at Kvalpynten, SW Edgeøya in East Svalbard. ... -
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 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 ... -
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 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 ... -
