Normal fault growth and fault zone architecture of normal faults exposed in the Corinth Canal, central Greece
(Master thesis, 2016-08-22)The Corinth Canal in central Greece consists of an excellent natural transect across a population of normal faults. This study presents a structural analysis of 23 exposed faults, focusing on fault geometry, fault zone ... -
Normal Fault Kinematics and the Role of Lateral Tip Retreat: An Example From Offshore NW Australia
(Journal article; Peer reviewed, 2021)Understanding how normal faults grow is key to determining the tectono-stratigraphic evolution of rifts. According to recent studies, normal faults tend to grow in two temporally distinct stages: a lengthening stage, ... -
Northeast Atlantic breakup volcanism and consequences for Paleogene climate change – MagellanPlus Workshop report
(Peer reviewed; Journal article, 2019-12-02)The northeast Atlantic encompasses archetypal examples of volcanic rifted margins. Twenty-five years after the last ODP (Ocean Drilling Program) leg on these volcanic margins, the reasons for excess melting are still ... -
Northern hemisphere glaciation during the globally warm early late Pliocene
(Peer reviewed; Journal article, 2013-12-12)The early Late Pliocene (3.6 to ,3.0 million years ago) is the last extended interval in Earth’s history when atmospheric CO2 concentrations were comparable to today’s and global climate was warmer. Yet a severe global ... -
Northward shifts in the polar front preceded Bølling and Holocene warming in southwestern Scandinavia
(Journal article; Peer reviewed, 2020)The last deglaciation in northern Europe provides an opportunity to study the hydrologic component of abrupt climate shifts in a region with complex interactions between ice sheets and oceanic and atmospheric circulation. ... -
Norwegian margin outer shelf cracking: a consequence of climate-induced gas hydrate dissociation?
(Peer reviewed; Journal article, 2010)A series of en echelon cracks run nearly parallel to the outer shelf edge of the mid-Norwegian margin. The features can be followed in a *60-km-long and *5-km-wide zone in which up to 10-m-deep cracks developed in the ... -
Numerical simulation of turbidity currents: a new perspective for small- and large-scale sedimentological experiments
(Master thesis, 2007)Turbidity currents are a variety of subaqueous sediment-gravity flows, in which the suspension of sediment by water turbulence produces a water-sediment mixture that is denser than the ambient water and hence flows due to ... -
Observing system evaluation based on ocean data assimilation and prediction systems: On-going challenges and future vision for designing/supporting ocean observational networks
(Peer reviewed; Journal article, 2019-07-29)This paper summarizes recent efforts on Observing System Evaluation (OS-Eval) by the Ocean Data Assimilation and Prediction (ODAP) communities such as GODAE OceanView and CLIVAR-GSOP. It provides some examples of existing ... -
Ocean circulation changes off southern Greenland during the abrupt climate events of mid-to-late MIS3
(Doctoral thesis, 2021-03-18)Marine sediment cores from the North Atlantic and ice cores from the Greenland Ice Sheet serve as natural archives of past climate variability. Ice cores have revealed that during the last glacial period the climate comprises ... -
An oceanic perspective on Greenland’s recent freshwater discharge since 1850
(Journal article; Peer reviewed, 2019)Instrumental data evidence an accelerating freshwater release from Arctic sea ice export and the Greenland Ice Sheet over the past three decades causing cooling and freshening in the subpolar North Atlantic region. However, ... -
On how the power supply shapes microbial survival
(Journal article; Peer reviewed, 2021)Understanding how environmental factors affect microbial survival is an important open problem in microbial ecology. Patterns of microbial community structure have been characterized across a wide range of different ... -
On integration of rock physics in quantitative seismic interpretation

On the applicability of a renormalized Born series for seismic wave modelling in strongly scattering media
(Peer reviewed; Journal article, 2020)Scattering theory is the basis for various seismic modeling and inversion methods. Conventionally, the Born series suffers from an assumption of a weak scattering and may face a convergence problem. We present an application ... -
On the biogenicity of Fe-oxyhydroxide filaments in silicified low-temperature hydrothermal deposits: Implications for the identification of Fe-oxidizing bacteria in the rock record
(Peer reviewed; Journal article, 2020)Microaerophilic Fe(II)‐oxidizing bacteria produce biomineralized twisted and branched stalks, which are promising biosignatures of microbial Fe oxidation in ancient jaspers and iron formations. Extracellular Fe stalks ... -
On the evolution of the North Atlantic -from continental collapse to oceanic accretion
(Doctoral thesis; Peer reviewed, 2013-10-23)The North Atlantic between Iceland and Svalbard and surrounding continental areas represent an ideal laboratory for studying plate tectonic processes, due to the presence of well exposed continent-continent collision ... -
On the relative importance of global and squirt flow in cracked porous media
(2011)A unified theory of global and squirt flow in cracked porous media was developed several years ago on the basis of a combination of the dynamic T-matrix approach to rock physics. The theory has been successfully used to ... -
The onset of flysch sedimentation in the Kaoko Belt (NW Namibia) – Implications for the pre-collisional evolution of the Kaoko–Dom Feliciano–Gariep orogen
(Peer reviewed; Journal article, 2017-09)Detrital zircon provenance study of a metamorphosed sedimentary succession in the eastern part of the Kaoko Belt in Namibia has revealed two distinct sources for the Neoproterozoic sedimentation along the southwestern Congo ... -
Ophiolites of the Central Asian Orogenic Belt: Geochemical and petrological characterization and tectonic settings
(Peer reviewed; Journal article, 2019)We present a compilation of published data (field, petrography, ages and geochemistry) from 73 ophiolitic complexes of the Central Asian Orogenic Belt. The ophiolitic complexes, ranging in age from Neoproterozoic to Triassic, ... -
