Case study of combined marine- and land-based passive seismic surveying in front of Nordenskiöldbreen outlet glacier, Adolfbukta, Svalbard
(Journal article; Peer reviewed, 2023)Glaciers generate seismic waves due to calving and fracturing, meaning that recording and following event classification can be used to monitor glacier dynamics. Our aim with this study is to analyse seismic data acquired ... -
Causality from palaeontological time series
(Peer reviewed; Journal article, 2018-07)As custodians of deep time, palaeontologists have an obligation to seek the causes and consequences of long‐term evolutionary trajectories and the processes of ecosystem assembly and collapse. Building explicit process ... -
Causes of bias and uncertainty in fracture network analysis
(Peer reviewed; Journal article, 2019-04-24)Fault and fracture networks are analysed to determine the deformation history and to help with such applications as engineering geology and fluidflow modelling. These analyses rely on quantifying such factors as length, ... -
The Cenozoic western Svalbard margin: sediment geometry and sedimentary processes in an area of ultraslow oceanic spreading
(Peer reviewed; Journal article, 2011-04-17)The northeastern high-latitude North Atlantic is characterised by the Bellsund and Isfjorden fans on the continental slope off west Svalbard, the asymmetrical ultraslow Knipovich spreading ridge and a 1,000 m deep rift ... -
Centennial variability in Southeast Pacific Hydrography and its link to the Bipolar Seesaw
(Master thesis, 2019-12-11) -
Centennial-millennial scale variations in West Antarctic Ice Sheet discharge and their relationship to climate and ocean changes during the late Holocene
(Master thesis, 2017-06-23)The West Antarctic Ice Sheet (WAIS) may be highly sensitive to future warming and to ocean driven changes in subsurface melting. Understanding this sensitivity is critical as WAIS dynamics are a major source of uncertainty ... -
The chalk depositional system in the Central Graben – concepts of regional geology, sedimentology and stratigraphy
(Working paper, 2011-12-08) -
Changing provenance and stratigraphic signatures across the Triassic–Jurassic boundary in eastern Spitsbergen and the subsurface Barents Sea
(Journal article; Peer reviewed, 2022)A change to more sandstone dominated deposits and increasing condensation across the Triassic–Jurassic boundary is generally associated with improved reservoir quality in the Barents Sea. However, spatial and temporal ... -
Characterisation of extensional faults in carbonate rocks (Suez Rift, Egypt); with particular focus on the role of shale smear
(Master thesis, 2012-04-27)The distribution, composition and flow-properties of fault core and shale smear along faults in carbonate reservoirs is less well understood compared to faults in siliciclastic rocks. This study uses field data to characterize ... -
Characterization and Correction of Evaporative Artifacts in Speleothem Fluid Inclusion Isotope Analyses as Applied to a Stalagmite From Borneo
(Journal article; Peer reviewed, 2023)Fluid inclusion water isotope measurements in speleothems have great potential for paleoclimate studies as they enable the reconstruction of precipitation dynamics and land temperatures. Several previous observations, ... -
Characterization and Modelling of a faulted oil and gas field (Syria)
(Master thesis, 2013-06-16)The FC is a faulted oil and gas field located onshore, in the southeast of Syria along the Euphrates Graben. In the 2011, a static reservoir model was built by students of IFP School. The same database used in the 2011 ... -
Characterization of seabed properties from Scholte waves acquired on floating ice on shallow water
(Journal article; Peer reviewed, 2020)Seismic surveying of the coastal areas in the Arctic is best facilitated during wintertime when the sea ice is land-fast. This eases the logistics of the operation and assures that there is no damage made to the vulnerable ... -
Characterizing the distribution of microbial sulfate reduction in Loki`s Castle hydrothermal system of the Arctic Mid-Ocean Ridge (AMOR)
(Master thesis, 2016-06-01)Studies on the distribution of microbial sulfate reduction, and its impact on the global carbon and sulfur cycle, have mostly been conducted in shallow and deep-marine sediments. Little is therefore known about the ecological ... -
Chemical weathering on Eldsfjellet, Meland municipality, western Norway
(Master thesis, 2012-11-27)The Subject of this master thesis was to define the chemical weathering processes, create a weathering chain from sink to source and to evaluate the degree of weathering on Eldsfjellet, Meland municipality in western Norway. ... -
Chlamydial contribution to anaerobic metabolism during eukaryotic evolution
(Journal article; Peer reviewed, 2020)The origin of eukaryotes is a major open question in evolutionary biology. Multiple hypotheses posit that eukaryotes likely evolved from a syntrophic relationship between an archaeon and an alphaproteobacterium based on ... -
Chronology of Early to Mid-Pleistocene sediments in the northern North Sea: New evidence from amino acid and strontium isotope analyses
(Journal article; Peer reviewed, 2022)Sediments deposited during glacial-interglacial cycles through the Early to Mid-Pleistocene in the North Sea are chronologically poorly constrained. To contribute to the chronology of these units, amino acid racemization ... -
The chronology of reindeer hunting on Norway's highest ice patches
(Peer reviewed; Journal article, 2018-01-24)The melting of perennial ice patches globally is uncovering a fragile record of alpine activity, especially hunting and the use of mountain passes. When rescued by systematic fieldwork (glacial archaeology), this evidence ... -
Citizen Seismology in the Arctic
(Journal article; Peer reviewed, 2020)Landslides, earthquakes and other natural disasters are expected to increase in the Arctic, yet our ability to make informed decisions about safety is tightly limited by lack of data. As part of the Integrated Arctic ... -
Climate adaptation of pre-Viking societies
(Journal article; Peer reviewed, 2022)Understanding how the Viking societies were impacted by past climate variability and how they adapted to it has hardly been investigated. Here, we have carried out a new multi-proxy investigation of lake sediments, including ... -
Climate in Svalbard 2100
(Research report, 2019-01)This report was commissioned by the Norwegian Environment Agency in order to provide basic information for use in climate change adaptation in Svalbard. It includes descriptions of historical, as well as projections for ...
