Salt decollement and rift inheritance controls on crustal deformation in orogens
(Journal article; Peer reviewed, 2019-09)We investigate the factors that control the shortening distribution and its evolution through time in orogenic belts using numerical models. We present self‐consistent high‐resolution numerical models that simulate the ... -
Sand textural control on shear-enhanced compaction bands in poorly-lithified sandstone
(Peer reviewed; Journal article, 2014)Sand textural control on SECB (shear-enhanced compaction band) formation is analyzed combining field observations, detailed material characterization and mechanical testing for poorly lithified sandstone units in Provence ... -
Scanarray-a broadband seismological experiment in the baltic shield
(Journal article; Peer reviewed, 2021)The ScanArray international collaborative program acquired broadband seismological data at 192 locations in the Baltic Shield during the period between 2012 and 2017. The main objective of the program is to provide ... -
Scattering approaches to modelling and inversion of acoustic and elastic waveform data
(Doctoral thesis, 2023-11-16)Spredningsmetoden er kraftig for å løse direkte og inverse spredningsproblemer i forskjellige bølgespredningsscenarioer. Full bølgeforminversjon, sett på som et ikke-lineært invers spredningsproblem, fremstår som en sentral ... -
Sea ice in the Nordic Seas: Greenland stadial to interstadial changes
(Journal article; Peer reviewed, 2024)Sea ice conditions in the eastern Fram Strait between 40 and 36.5 ka b2k (thousand years before the year 2000) are reconstructed in detail, based on biomarker analyses. Following extensive sea ice conditions around the ... -
Sea ice thickness from air-coupled flexural waves
(Journal article; Peer reviewed, 2021)Air-coupled flexural waves (ACFWs) appear as wave trains of constant frequency that arrive in advance of the direct air wave from an impulsive source travelling over a floating ice sheet. The frequency of these waves varies ... -
Sea Ice Variability in a Warmer Past: Last Interglacial Paleoceanography of the (Sub)Arctic Oceans
(Doctoral thesis, 2024-05-13)Det omfattende og permanente havisdekket som i dag karakteriserer det Arktiske havet er i rask endring med en havoverflate som uunngåelig er i endring fra hvit til blå. Forståelse for en slik omfattende endring og dets ... -
Sea ice variability in the Nordic Seas over Dansgaard–Oeschger climate cycles during the last glacial – A biomarker approach
(Doctoral thesis, 2019-02-15)The Arctic sea ice cover is in fast transition. Resolving past sea ice fluctuations and its link with abrupt climate change might be key for a better understanding of yet unknown climatic consequences of future Arctic sea ... -
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 ... -
Sediment flux variation as a record of climate change in the Late Quaternary deep-water active Corinth Rift, Greece
(Journal article; Peer reviewed, 2024)The value of deep-water sedimentary successions as reliable records of environmental change has been questioned due to their long response times and sediment pathways leading to complex responses to climatic change 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 ... -
