Some sedimentological and structural studies of the old red sandstone Hitra group, Hitra, Sør-Trøndelag
(Master thesis, 1986-06)The Old Red Sandstone (O.R.S.) area on Hitra contains an about 1350 m thick, continental succession of conglomerates, sandstones and mudstones, here referred to as the Hitra Group. It has further been divided into 3 ... -
Source and receiver deghosting by demigration-based supervised learning
(Journal article; Peer reviewed, 2022)Deghosting of marine seismic data is an important and challenging step in the seismic processing flow. We describe a novel approach to train a supervised convolutional neural network to perform joint source and receiver ... -
Source Study of the 24 August 2016 Mw 6.8 Chauk, Myanmar, Earthquake
(Journal article; Peer reviewed, 2018)The source process of an intraslab intermediate‐depth earthquake (h=90 km) that occurred near Chauk, central Myanmar, on 24 August 2016 was investigated using teleseismic body‐wave inversion. The focal mechanism solution ... -
Source-Sink Analysis of the Pleistocene sediment routing systems within the Wasatch Mountains, Salt Lake City segment, Utah
(Master thesis, 2013-06-03)Source-sink studies consider the sedimentary systems holistically from the erosional hinterland to the depositional basin. Such studies are often challenged by poor constraint on key parameters controlling sediment production, ... -
Sources of uncertainty in Greenland surface mass balance in the 21st century
(Journal article; Peer reviewed, 2022)The surface mass balance (SMB) of the Greenland ice sheet is subject to considerable uncertainties that complicate predictions of sea level rise caused by climate change. We examine the SMB of the Greenland ice sheet in ... -
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 ...
