Open AccessAtlantic inflow and low sea-ice cover in the Nordic Seas promoted Fennoscandian Ice Sheet growth during the Last Glacial Maximum
The Atlantic water inflow into the Nordic Seas has proven difficult to reconstruct for the Last Glacial Maximum. At that time, the Fennoscandian Ice Sheet grew potentially to its maximum extent. Sea-ice free c...

Open AccessRevised Storegga Slide reconstruction reveals two major submarine landslides 12,000 years apart
The Storegga Slide is the largest known exposed submarine landslide in the world, which triggered a tsunami that inundated the coasts of northern Europe ~8,150 years ago. Previous studies suggested the removal...

Open AccessPalaeo-productivity record from Norwegian Sea enables North Atlantic Oscillation (NAO) reconstruction for the last 8000 years
The North Atlantic Oscillation is the dominant atmospheric driver of North Atlantic climate variability with phases corresponding to droughts and cold spells in Europe. Here, we exploit a suggested anti-correl...

Eurasian Ice Sheet collapse was a major source of Meltwater Pulse 1A 14,600 years ago
Rapid sea-level rise caused by the collapse of large ice sheets is a threat to human societies. In the last deglacial period, the rate of global sea-level rise peaked at more than 4 cm yr−1 during Meltwater Pulse...

Open AccessAuthor Correction: Glacigenic sedimentation pulses triggered post-glacial gas hydrate dissociation
The original version of this Article contained an error in the second sentence of the Abstract, which incorrectly read ‘They are stable under high pressure and low, but react sensitively to environmental chang...

Open AccessGlacigenic sedimentation pulses triggered post-glacial gas hydrate dissociation
Large amounts of methane are stored in continental margins as gas hydrates. They are stable under high pressure and low temperature, but react sensitively to environmental changes. Bottom water temperature and...

First Results of the Geotechnical In Situ Investigation for Soil Characterisation Along the Upper Slope Off Vesterålen: Northern Norway
High-resolution geophysical data reveal the presence of several spatially-isolated, small-scale landslides along the gently dip** (~3–4°) upper slope off Vesterålen, Northern Norway. Dynamic slope stability ...

Postglacial Mass Failures in the Inner Hardangerfjorden System, Western Norway
Based on high-resolution bathymetric records, sub-bottom profiles and sediment cores, we study postglacial mass transport deposits, slide scar complexes, cyclic steps and rockfall deposits as indicators of mas...

Sediment Failure Affecting Muddy Contourites on the Continental Slope Offshore Northern Norway: Lessons Learned and Some Outstanding Issues
The formerly glaciated continental margin off Norway has experienced a relatively large number of submarine landslides of varying sizes, volumes, and ages originating from contourites deposited on the continen...

An In-Situ Free-Fall Piezocone Penetrometer for Characterizing Soft and Sensitive Clays at Finneidfjord (Northern Norway)
The identification and characterization of weak layers, potentially acting as detachment planes, are key elements in submarine landslide research. In this study, the MARUM Free-Fall Piezocone Penetrometer (FF-...

Investigations of Slides at the Upper Continental Slope Off Vesterålen, North Norway
Multibeam bathymetry, high-resolution seismic profiles and sediment cores were collected from the upper continental slope outside Andøya, the northernmost island in Vesterålen, northern Norway (69°N). Eight sm...

Identification of Weak Layers and Their Role for the Stability of Slopes at Finneidfjord, Northern Norway
The 1996 Finneidfjord landslide, which took four human lives in northern Norway, initiated along a weak layer in the fjord-marine sediments before develo** retrogressively across the shoreline. The integrati...

Shallow Landslides and Their Dynamics in Coastal and Deepwater Environments, Norway
In this manuscript, we present the first results of integrated slope stability studies to investigate smaller-scale mass movement processes in different physiographic settings of Norway. These include coastal ...

Open AccessThe Cenozoic western Svalbard margin: sediment geometry and sedimentary processes in an area of ultraslow oceanic spreading
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 ...

Sedimentary and structural control on pockmark development—evidence from the Nyegga pockmark field, NW European margin
The Nyegga region, located at water depths of about 600–800 m on the NW European continental margin, contains more than 200 pockmarks. Recently collected TOPAS seismic profiles and EM1002 bathymetric records n...

Origin of pockmarks and chimney structures on the flanks of the Storegga Slide, offshore Norway
Seafloor pockmarks and subsurface chimney structures are common on the Norwegian continental margin north of the Storegga Slide scar. Such features are generally inferred to be associated with fluid expulsion,...

Seismic analyses of Cenozoic contourite drift development in the Northern Norwegian Sea
Four drift accumulations have been identified on the continental margin of northern Norway; the Lofoten Drift, the Vesterålen Drift, the Nyk Drift and the Sklinnadjupet Drift. Based on seismic character these ...

Stratigraphy of fossil pigments and Cladophora and its relationship with deposition of tephra in Lake Mývatn, Iceland
Fossil plant pigments and Cladophora fragments were analyzed in a 6.53 m long sediment profile from Lake Mývatn, Iceland, covering most of its history of about 2300 years. A decrease in myxoxanthophyll (produced ...
