Sea ice variability in the North Atlantic subpolar gyre throughout the last interglacial
(Journal article; Peer reviewed, 2023)The Last Interglacial period, Marine Isotope Stage 5e (MIS 5e ∼116–128 ka), is thought to have had a warmer, but less stable climate than the present interglacial. One key factor that has the potential to influence the ... -
Sea ice variability in the southern Norwegian Sea during glacial Dansgaard-Oeschger climate cycles
(Peer reviewed; Journal article, 2019-03-06)The last glacial period was marked by pronounced millennial-scale variability in ocean circulation and global climate. Shifts in sea ice cover within the Nordic Seas are believed to have amplified the glacial climate ... -
Seafloor earthquake ruptures and mass wasting from the 2004 Mw 6.3 Les Saintes submarine earthquake
(Journal article; Peer reviewed, 2023)The seismic hazard posed by submarine faults and the capacity of submarine earthquakes to trigger mass wasting are poorly understood because we lack detailed characterizations of coseismic ruptures at the seafloor. Here, ... -
Seafloor expression and shallow structure of a surfacing fold-and-thrust system: an example from Isfjorden, West Spitsbergen
(Peer reviewed; Journal article, 2012)A detailed map of the structure of the West Spitsbergen Fold-and-Thrust Belt in the shallow part of the Isfjorden area, Spitsbergen, is presented. The map was constructed from a new dense grid of 2D multichannel reflection ... -
The seasonal evolution of subglacial drainage pathways beneath a soft-bedded glacier
(Journal article; Peer reviewed, 2022)Subglacial hydrology is a key element in glacier response to climate change, but investigations of this environment are logistically difficult. Most models are based on summer data from glaciers resting on rigid bedrocks. ... -
Seasonal sea ice persisted through the Holocene Thermal Maximum at 80°N
(Journal article; Peer reviewed, 2021)The cryospheric response to climatic warming responsible for recent Arctic sea ice decline can be elucidated using marine geological archives which offer an important long-term perspective. The Holocene Thermal Maximum, ... -
Sediment deformation atop the Lomonosov Ridge, central Arctic Ocean: Evidence for gas-charged sediment mobilization
(Journal article; Peer reviewed, 2022)We have used a hovercraft platform drifting with the sea ice to acquire the first digitally recorded seismic reflection data transects across the Canada/Greenland (89°N-85°N) section of the Lomonosov Ridge, central Arctic ... -
Sediment dispersal and redistributive processes in axial and transverse deep-time source-to-sink systems of marine rift basins: Dampier Sub-basin, Northwest Shelf, Australia
(Journal article; Peer reviewed, 2021)Morphological scaling relationships between source‐to‐sink segments have been widely explored in modern settings, however, deep‐time systems remain difficult to assess due to limited preservation of drainage basins and ... -
The Sediment Green-Blue Color Ratio as a Proxy for Biogenic Silica Productivity Along the Chilean Margin
(Journal article; Peer reviewed, 2022)Sediment cores recently collected from the Chilean Margin during D/V JOIDES Resolution Expedition 379T (JR100) document variability in shipboard-generated records of the green/blue (G/B) ratio. These changes show a strong ... -
Sediment supply controls on sequence stratigraphy
(Master thesis, 2012-06-01)A three-dimensional numerical model of deltaic deposition is used to study the influence of sediment supply changes on delta development. Sediment supply will have a cyclic variation under conditions of constant linear sea ... -
Sedimentary analysis of the deep-water (Pliocene) Pellini Member, Corinth Rift, Greece
(Master thesis, 2016-08-23)This sedimentological study focuses on the architectural elements distinguished within the deep-water Pellini Member. The Pellini Member is located south of the active Corinth rift, within the uplifted and incised ... -
Sedimentary anatomy and hydrological record of relic fluvial deposits in a karst cave conduit
(Journal article; Peer reviewed, 2021)This case study from the renowned Demänová Cave System in the Carpathians of Slovakia demonstrates that the conventional methods of fluvial sedimentology, combined with an allostratigraphic mapping and speleothem U-series ... -
Sedimentary ancient DNA reveals local vegetation changes driven by glacial activity and climate
(Journal article; Peer reviewed, 2023)Disentangling the effects of glaciers and climate on vegetation is complicated by the confounding role that climate plays in both systems. We reconstructed changes in vegetation occurring over the Holocene at Jøkelvatnet, ... -
Sedimentary ancient DNA shows terrestrial plant richness continuously increased over the Holocene in northern Fennoscandia
(Journal article; Peer reviewed, 2021)The effects of climate change on species richness are debated but can be informed by the past. Here, we generated a sedimentary ancient DNA dataset covering 10 lakes and applied novel methods for data harmonization. We ... -
Sedimentary architecture of sand bodies in the shallow marine Endalen Member, Firkanten Formation (Paleocene) of the Adventdalen Area, Svalbard
(Master thesis, 2018-06-30)The Firkanten Formation has been the object of many research projects, but due to the economic interests in the lower coal bearing Todalen Member, the upper Endalen Member has received little attention. The Endalen Member ... -
Sedimentary deposits and bioturbation in an Early Cretaceous subarctic stormy greenhouse shelf environment
(Journal article; Peer reviewed, 2023)This study of the Aptian lower part of the Carolinefjellet Formation in Svalbard, Norwegian high Arctic, is based on well cores and outcrop section in the Adventdalen area of Spitsbergen and reports on the deposits and ... -
Sedimentary response to tectonism and rifting in basins on the Norwegian shelf and onshore Norway
(Doctoral thesis, 2021-09-10)The Norwegian sedimentary basins offshore and onshore have in variable degree been influenced by tectonism as rifting and faulting during deposition. This stems from post Caledonian extensional events that affected both ... -
Sedimentation in a synclinal shallow-marine embayment: Coniacian of the North Sudetic Synclinorium, SW Poland
(Journal article; Peer reviewed, 2020)This study is a reconstruction of the Coniacian palaeogeographic and palaeoenvironmental development in the North Sudetic Basin, a synclinal trough within the Late Cretaceous Central European seaway linking the Boreal and ... -
The sedimentation pattern of the last deglaciation and postglacial phase in a high-arctic valley: Endalen, Spitsbergen
(Master thesis, 2000)The present study, focused in the valley-side gravel fans in the eastern part of Endalen and the adjoining side-slope of Adventdalen, has contributed to an understanding of the spatial pattern of the late Weichselian ... -
