We present the first observations, to our knowledge, of a new class of high‐latitude mesosphere‐stratosphere‐troposphere radar echoes from the E region as observed with the Arctic Lidar Observatory for Middle Atmosphere Research wind radar during the period 2004–2008. These echoes occur primarily during the summer months and in the altitude range from 93 to 114 km, with a pronounced peak of maximum ...

Changes in Arctic sea ice have raised questions about changes in sea ice drift patterns. Reduced sea ice coverage may open up the Arctic to further exploration of maritime activities, particularly during the summer months. Given such changes, it is important to investigate differences between available sea ice drift products. Products based on synthetic aperture radar (SAR), radar scatterometer, and ...

High-resolution swath-bathymetry data integrated with sub-bottom profiles and single-channel seismics reveal an 18 km long, up to 1000 m wide and 10-15 m deep crack located approx. 4 km upslope from a slide scar on the continental slope off northern Norway. This crack is formed by subsidence of the sea-floor sediments to a depth of 120 m due to downslope movement of a ~80 km2 large sediment slab ...

During the Triassic, the Barents Sea Basin was filled with sediments from the Uralian and Caledonian mountain belts. High sediment yield and large river systems made progradation possible, resulting in an alluvial to deltaic plain stretching from the mountain belts in the south east to Spitsbergen in the north.This thesis focuses on the northwestern part of the Loppa High area, SW Barents Sea. The ...

In recent years, technology has had a vast impact on the sports industry, particularly in soccer. Elite soccer teams utilize digital information systems to quantify performance metrics, in order to assess their strengths and weaknesses. Applied methods mostly rely on post-game analytics, allowing coaches to review games in retrospect and implement corrections to their team thereafter. However, this ...

META-pipe is a metagenomic analysis service provided in the ELIXIR distributed life science infrastructure. It provides assembly of sequence data, functional annotation, and taxonomic profiling. The analysis is computationally intensive and it consist of many jobs which have different requirements and varying complexity and execution times It therefore requires an execution environment that can ...

An approximately 1 meter wide NE-SW-oriented mylonitic shear zone hosts hydrothermally precipitated quartz and carbonate veins. The shear zone mainly consists of a secondary mylonitic fabric enriched in chlorite. A similar mylonitic shear zone striking NE-SW, oriented parallel to the axial plane of a F3-fold, consists of the same secondary mylonitic chloritized fabric and are therefore assumingly ...

Rockfalls are blocks of rock that bounce and roll down slopes. They are commonly detached from rock-slopes with inclinations over 40-45°. They embody high energy and mobility and are a major cause of landslide related deaths. Rockfalls can be simulated using empirical relationships and modelling, of which 2D and 3D variants exist for the latter. 3D models allow for rock fragment- and surface shape ...

Unstable areas producing rock slope failures come with large consequences. The understanding of why and where they might occur is necessary to mitigate damage and prevent casualties. A total of 133 unstable rock slopes have been detected in Troms, Northern Norway, evidencing that a great focus on these geohazards is important. This study has focused on seven unstable rock slopes in Kåfjorden, Troms, ...

The stability of contemporary ice sheets is influenced by the discharge from ice streams - corridors of fast-flowing ice bounded by ice flowing an order of magnitude slower. Reconstructions of palaeo-ice stream dynamics contribute to our understanding of ice stream sensitivity to the ocean-climate system and can aid in the numerical modelling and prediction of future changes in contemporary ice ...
