Cambrian (Series 3 - furongian) conodonts from the alum shale formation at Slemmestad, Oslo region, Norway
(Peer reviewed; Journal article, 2018-05-09)Nine samples from the Alum Shale of Slemmestad, Oslo Region, were processed for conodonts. The limestone-rich interval extending from the mid Cambrian Paradoxides paradoxissimus trilobite Zone to the Lower Ordovician ... -
Can we use ice sheet reconstructions to constrain meltwater for deglacial simulations?
(Peer reviewed; Journal article, 2012)Freshwater pulses from melting ice sheets are thought to be important for driving deglacial climate variability. This study investigates challenges in simulating and understanding deglacial climate evolution within this ... -
"Candidatus Subterrananammoxibiaceae," a New Anammox Bacterial Family in Globally Distributed Marine and Terrestrial Subsurfaces
(Journal article; Peer reviewed, 2023)Bacteria specialized in anaerobic ammonium oxidation (anammox) are widespread in many anoxic habitats and form an important functional guild in the global nitrogen cycle by consuming bio-available nitrogen for energy rather ... -
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 ... -
The chalk depositional system in the Central Graben – concepts of regional geology, sedimentology and stratigraphy

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 ... -
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 ... -
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 transition at the Eocene-Oligocene influenced by bathymetric changes to the Atlantic-Arctic oceanic gateways
(Journal article; Peer reviewed, 2022)The Eocene–Oligocene Transition (∼33.9 Ma) marks the largest step transformation within the Cenozoic cooling trend and is characterized by a sudden growth of the Antarctic ice sheets, cooling of the interior ocean, and the ... -
Climate variability in the subarctic area for the last 2 millennia
(Peer reviewed; Journal article, 2018-01-25)To put recent climate change in perspective, it is necessary to extend the instrumental climate records with proxy data from paleoclimate archives. Arctic climate variability for the last 2 millennia has been investigated ... -
Climate, glacial and vegetation history of the Polar Ural Mountains since early MIS 2 inferred from a 54-m-long sediment core from Lake Bolshoye Shuchye
(Journal article; Peer reviewed, 2021)Because continuous and high-resolution records are scarce in the polar Urals, a multiproxy study was carried out on a 54 m long sediment succession (Co1321) from Lake Bolshoye Shchuchye. The sedimentological, geochemical, ... -
A climatic trigger for the giant Troll pockmark field in the northern North Sea
(Peer reviewed; Journal article, 2017-04)Pockmarks are seafloor craters usually formed during methane release on continental margins. However, the mechanisms behind their formation and dynamics remain elusive. Here we report detailed investigations on one of the ... -
Clinoform systems: Review and dynamic classification scheme for shorelines, subaqueous deltas, shelf edges and continental margins
(Peer reviewed; Journal article, 2018-10)Clinoforms are inclined and normally basinward-dipping horizons developed over a range of spatial and temporal scales in both siliciclastic and carbonatic systems. The study of clinoform successions underpins sequence ...
