The upper continental slope of the Storfjorden-Kveithola Trough Mouth Fans (NW Barents Sea) contains a several m-thick late Pleistocene sequence plumites composed laminated mud interbedded with sand/silt layers. Radiocarbon ages revealed that deposition occurred during about 130 years at very high sedimentation rate 3.4 cm a−1, 7 km from present shelf break. Palaeomagnetic and rock magnetic analyses confirm existence prominent, short-living sedimentary event. appear laterally continuous were correlated sequences described west Svalbard neighboring glacial depositional systems representing major event regional scale appointed to correspond deep-sea record Meltwater Pulse-1a.
