Southern Ocean bottom-water cooling and ice sheet expansion during the middle Miocene climate transition
(Journal article; Peer reviewed, 2021)The middle Miocene climate transition (MMCT), around 14 Ma, was associated with a significant climatic shift, but the mechanisms triggering the event remain enigmatic. We present a clumped isotope (Δ47) bottom-water ... -
Spatial and temporal variations in minibasin geometry and evolution in salt tectonic provinces: Lower Congo Basin, offshore Angola
(Journal article; Peer reviewed, 2021)In passive margin salt basins, the distinct kinematic domains of thin‐skinned extension, translation and contraction exert important controls on minibasin evolution. However, the relationship between various salt minibasin ... -
Spatial patterns of North Atlantic Oscillation influence on mass balance variability of European glaciers
(Peer reviewed; Journal article, 2012-06-14)We present and validate a set of minimal models of glacier mass balance variability. The most skillful model is then applied to reconstruct 7735 individual time series of mass balance variability for all glaciers in the ... -
Spatio-temporal development of a joint network and its properties: a case study from Lilstock, UK
(Master thesis, 2019-06-26)The aim of this study is to investigate the spatial distribution and scaling properties of various joint sets, with particular focus on the temporal development of network properties and the influence of pre-existing ... -
Spatio-temporal evolution of earthquake swarms in the Nordland area of Norway
(Master thesis, 2016-06-15)The double difference earthquake relocation method (DD) is used to improve the seismicity image for regions with high seismic activity. Common location techniques include standard hypocenter location (absolute locations) ... -
Spatio-temporal patterns of Pyrenean exhumation revealed by inverse thermo-kinematic modeling of a large thermochronologic data set
(Journal article; Peer reviewed, 2021)Large thermochronologic data sets enable orogen-scale investigations into spatio-temporal patterns of erosion and deformation. We present the results of a thermo-kinematic modeling study that examines large-scale controls ... -
A spatio-temporal reconstruction of sea-surface temperatures in the North Atlantic during Dansgaard-Oeschger events 5–8
(Journal article, 2017-08-24)Here we establish a spatio-temporal evolution of the sea-surface temperatures in the North Atlantic over Dansgaard Oeschger (DO) events 5–8 (c. 30–40 ka) using the proxy surrogate reconstruction method. Proxy data suggest ... -
Spatio-temporal variability of Arctic summer temperatures over the past 2 millennia
(Peer reviewed; Journal article, 2018-04-24)In this article, the first spatially resolved and millennium-length summer (June–August) temperature reconstruction over the Arctic and sub-Arctic domain (north of 60°N) is presented. It is based on a set of 44 annually ... -

Spring-summer temperature reconstruction in western Norway 1734-2003: a data-synthesis approach
(Peer reviewed; Journal article, 2003-12-16)A series of spring–summer (April–August) temperatures was reconstructed for the period 1734–1923 for western Norway based on multi-proxy data. For the period 1734–1842 the long-term variations were based on terminal moraines ... -
Sr/Ca in Calcitic Tests of Benthic Foraminifera - A Potential Water-Depth Proxy?
(Peer reviewed; Journal article, 2009)Well-preserved low-Mg calcite tests of modern benthic foraminifera from a depth transect off SW Norway show decreasing Sr/Ca with increasing water depth (r = –0.84). The Mg/Ca ratios also decrease with increasing water ... -
Stable Biological Production in the Eastern Equatorial Pacific Across the Plio-Pleistocene Transition (∼3.35–2.0 Ma)
(Journal article; Peer reviewed, 2021)Upwelling within the Eastern Equatorial Pacific (EEP) Ocean is a key factor for the Earth's climate because it supports >10% of the present-day biological production. The dynamics of upwelling in the EEP across the ... -
Stable oxygen isotope reconstruction of temperature exposure of the Icelandic cod (Gadus morhua) stock over the last 100 years
(Journal article; Peer reviewed, 2020)Increasing water temperatures are predicted around the globe, with high amplitudes of warming in Subarctic and Arctic regions where Atlantic cod (Gadus morhua) populations currently flourish. We reconstructed oxygen isotope ... -
Stable Southern Hemisphere westerly winds throughout the Holocene until intensification in the last two millennia
(Journal article; Peer reviewed, 2022)The Southern Hemisphere westerly winds sustain the Southern Ocean’s role as one of Earth’s main carbon sinks, and have helped sequester nearly half the anthropogenic CO2 stored in the ocean. Observations show shifts in the ... -
The start of a major sea-level rise indicates that icesheet expansion in western Norway commenced before the Younger Dryas
(Journal article, 2007)The relative sea level rose 10 m on Sotra, western Norway, during the Younger Dryas (YD). Based on dating of isolation basins, the transgression started in late Allerød at ~13 110 and ended in late YD at ~11 780 cal yr BP, ... -
Static and dynamic elastic behaviour of siliciclastic reservoir rocks
(Doctoral thesis, 2013-06-24)Siliciclastic rocks are composed of a wide range of minerals; including quartz, feldspar, clay minerals, calcite to name the most common; and various textural properties such as grain size (sorting), shape, orientation and ... -
The Storfjorden, Svalbard, earthquake sequence 2008-2020: Transtensional tectonics in an arctic intraplate region
(Journal article; Peer reviewed, 2021)An earthquake sequence in the Storfjorden offshore area southwest of Spitsbergen in the Svalbard archipelago initiated with a 21 February 2008 magnitude Mw 6.1 event. This area had previously not produced any significant ... -
Straight from the source's mouth: controls on field-constrained sediment export across the entire active Corinth Rift, central Greece
(Journal article; Peer reviewed, 2020)The volume and grain‐size of sediment supplied from catchments fundamentally control basin stratigraphy. Despite their importance, few studies have constrained sediment budgets and grain‐size exported into an active rift ... -
Strain migration during multiphase extension, Stord Basin, northern North Sea rift
(Journal article; Peer reviewed, 2021)In regions experiencing multiple phases of extension, rift‐related strain can vary along and across the basin during and between each phase, and the location of maximum extension can differ between the rift phase. Despite ...
