Slettind in Flaktstad municipality, Lofoten in Nordland, has numerous rockfalls throughout the year. Rockfalls hit Fv 805 on a weekly basis, and it is estimated the most dangerous road in Nordland county. A rock avalanche hit the road winter 2017 closing it for 2 weeks, and isolating the small village Myrland. Statens Vegvesen consider to build a tunnel to protect the road but the failure mechanisms ...

Light absorbing particles (LAPs) such as black carbon (BC) and dust can reduce snow albedo and have a positive radiative forcing. Previous studies investigating LAP in snow in Tromsø focused on black carbon (BC) also called elemental carbon because it has human sources, but dust should also be considered because, while largely from natural sources, it is present in higher concentrations. To quantify ...

Lofoten utgjør en opphevet horst i forhold til omkringliggende bassenger og består hovedsakelig av prekambrisk grunnfjell. Tidligere modeller viser at landområdene og sokkelområdene utenfor Lofoten ser ut til å ha hatt en lik ekstensjonshistorie med flere faser av forkastningsbevegelser, innsynkning og oppheving gjennom mesozoikum og kenozoikum. Steile strukturer i berggrunnen danner svakhetssoner ...

The sedimentary environment and seismic anomalies of the upper Brygge and Kai formations on the northern part of the Mid-Norwegian Continental Shelf is analysed from 3D seismic data and the exploration well 6604/2-1. This was done in order to give a better understanding of the paleo-climatic development in the period before the establishment of the large-scale ice sheets of the Northern Hemisphere, ...

Swath bathymetry, high resolution seismic and core data are analysed to describe the Late Weichselian and Holocene sedimentary processes and palaeoenvironment in Van Keulenfjorden, Spitsbergen. Bottom currents, the bathymetry of the fjord and the distance from sediment sources are the controlling factors for the sediment distribution as indicated by isopach maps. Sandur deltas at the mouth of ...

Multi-proxy analyses of five sediment cores (including lithostratigraphy, physical properties and XRF-scanning) and analyses of swath bathymetry and high resolution seismic data were integrated in order to reconstruct the Holocene glacial history and paleoenvironment of Moskusoksefjord and inner parts of Nordfjord, North-East Greenland. In Moskusoksefjord, the large-scale bathymetry is divided ...

Grounding zone wedges and ridges throughout the Barents Sea gives good spatial constraints of the Late Weichselian deglaciation of the Barents Sea, however, little is known about Late Weichselian ice dynamics in the Central Barents Sea, primarily due to a lack of data. The study is carried out south of Sentralbanken in Sentralbankrenna which was likely an important source area feeding the Bjørnøyrenna ...

Hydrothermal vents are the result of the interaction between seawater and magma and occur at regular intervals along mid ocean ridges. The first visual confirmation of plumes was done in 1977. The detection of hydrothermal plumes has both provided indirect evidence for their existence and a resolution of the occurrences . In deep ocean with low sedimentation rates, hydrothermal plumites have the ...

Thick succession of suspension settled muds, deposited from meltwater plumes, which are frequently interbedded with sandy mass flows deposits. Between conformable beds, discrete units have been in intensely deformed, often into large recumbent folds with complex structure. Suspension settled muds are observed in three distinct structural facies, namely massive clays, rhythmically banded muds and ...

Den nedre delen av Breivikeidet er dominert av postglasiale grunnmarine sedimenter. Den glacio-isostatiske hevning av landmassen har gradvis senket erosjonsbasis og ført til blottleggelse av eldre sedimentene der elvene har skåret seg ned i disse. Den nederste delen av de undersøkte avsettingene er tolket som bottomsets med en rik skeletal fauna dominert av muslinger mens snegler og rester av rur ...
