A Late Pleistocene submarine slide on the Bear Island Trough Mouth Fan
A large submarine slide on the southern flank of the Bear Island Trough Mouth Fan, southwestern Barents Sea continental slope, has a run-out distance of about 400 km, a total volume of about 1100 km3, and is youn...

The glacier-fed fan at the mouth of Storfjorden trough, western Barents Sea: a comparative study
The Middle and Late Pleistocene succession on the glacier-fed fan at the mouth of Storfjorden trough was studied using high-resolution seismic data. Seven glacial advances to the shelf break during Middle and ...

On the origin and flow behavior of submarine slides on deep-sea fans along the Norwegian–Barents Sea continental margin
Debris lobes with characteristic lengths, widths, and thickness of 30–200 km, 2–10 km, and 10–50 m, respectively, represent the main building blocks of deep-sea fans along the Norwegian–Barents Sea continenta...

Inferred gas hydrate on the Barents Sea shelf — a model for its formation and a volume estimate
On the southwestern Barents Sea shelf, sediments containing gas hydrates that overlie free gas have been inferred from multichannel seismic data. The volume of suspected gas hydrate is tentatively estimated t...

The Trænadjupet Slide: Sediment Disintegration and Flow
The Trænadjupet Slide is located on the continental slope of Norway immediately NE of the Vøring Plateau (Dowdeswell et al. 1996). The slide-affected area extends from the shelf break to >3,000 m water depth in t...

Morphology of the Lofoten Basin Channel
A deep-sea channel system, the Lofoten Basin Channel, has been identified in the SE Lofoten Basin (Dowdeswell et al. 1996; Vorren et al. 1998). The channel represents the downslope continuation of the Andøya Cany...

Submarine Glacigenic Debris Flows on the Bear Island Trough Mouth Fan, Western Barents Sea: Aspects of Flow Behaviour
The Bear Island Trough Mouth Fan is situated in front of the Bear Island Trough in the western Barents Sea. The fan extends from the shelf break to water depths greater than 3,000 m and covers an area of appro...

Preconditions Leading to the Holocene Trænadjupet Slide Offshore Norway
The Traenadjupet Slide (14,100 km2) remobilised an up to 180 m thick package comprising late Weichselian glacigenic sediments and an underlying late Saalian — late Weichselian contourite drift. Rapid burial of th...

The Lofoten Contourite Drift: High-Resolution Seismic Stratigraphy
A contourite drift, the Lofoten Drift, has been identified from ca. 1,000 m water depth on the continental slope off northern Norway (Laberg et al. 1999) (Fig. 1). The Norwegian Current transporting Atlantic wate...

Slope Instability of Continental Margins
Giant submarine landslides occur on almost every contintental margin. Individual slides involve up to 20,000 km3 of slope material and cover an area of up to 113,000 km2. Their wide spread distribution and their ...

Submarine Paleo-Failure Morphology On A Glaciated Continental Margin From 3d Seismic Data
The morphology of two lower – middle Pleistocene paleo-slope surfaces within a muddy glacigenic succession was studied on 3D seismic data. The lower surface is characterised by irregular relief. It terminates ...

Internal deformation of a muddy gravity flow and its interaction with the seafloor (site C0018 of IODP Expedition 333, Nankai Trough, SE Japan)
The processes of flow deformation of marine mass-transport sediments, including their ability to affect the underlying substrate and add mass during sediment flow events, are addressed based on sedimentologica...

Geomorphology and development of a high-latitude channel system: the INBIS channel case (NW Barents Sea, Arctic)
The INBIS (Interfan Bear Island and Storfjorden) channel system is a rare example of a deep-sea channel on a glaciated margin. The system is located between two trough mouth fans (TMFs) on the continental slop...
