When the first Norwegian commercial catch of snow crabs was taken in the Barents Sea in 2012, an unexpected opportunity arose to create a new, profitable natural resource-based industry. However, hidden under the surface were massive biological, technological, and institutional uncertainties. This study first explores what motivated the entrepreneurs to invest in an industry exposed to extreme ...

A unicellular, heterotrophic, eukaryotic parasite was isolated from nearshore Arctic marine sediment in association with the diatom <i>Pleurosigma</i> sp. The parasite possessed ectoplasmic threads that could penetrate diatom frustules. Healthy and reproducing <i>Pleurosigma</i> cultures would begin to collapse within a week following the introduction of this parasite. The parasite (2–10 μm diameter) ...

Gammaherpesvirus infections have been described in cervids worldwide, mainly the genera <i>Macavirus</i> or <i>Rhadinovirus</i>. However, little is known about the gammaherpesviruses species infecting cervids in Norway and Fennoscandia. Blood samples from semi-domesticated (<i>n</i> = 39) and wild (<i>n</i> = 35) Eurasian tundra reindeer (<i>Rangifer tarandus tarandus</i>), moose (<i>Alces alces</i>, ...

Salmon gill poxvirus (SGPV) can cause serious gill disease in Atlantic salmon (<i>Salmo salar</i> L.) and represents a significant problem to aquaculture industries in Northern Europe. Here, a single-tube multi-locus variable-number tandem-repeat (VNTR) analysis (MLVA) genotyping assay, targeting eight VNTR loci, was developed for studying the epizootiology of SGPV. Through MLVA typing of SGPV ...

<p>Distributed version control systems are popular for storing source code, but they are notoriously ill suited for storing large binary files. <p>We report on the results from a set of experiments designed to characterize the behavior of some widely used distributed version control systems with respect to scaling. The experiments measured commit times and repository sizes when storing single files ...

Here we demonstrate how to get adhesion force maps with an amplitude-modulation AFM in tapping mode. Our method is tapping mode but it is carried out at ultra-small amplitudes in the presence of surface water layers. The tip is made to vibrated under the water layer in what we call Small Amplitude Small Set-point AM AFM. We show how this is done with an example based on the Cypher scanning probe ...

We model bioeconomic interrelations between a commercial fishery and an aquaculture industry by using a dynamical systems theory approach. The biomass follows a logistic growth where the pollution emerging from aquaculture is accounted for by means of a retardation term. We investigate the existence and stability of the equilibrium states of this model as a function of the growth-retardation parameter ...

This is a study of inter-organisational exercises arranged by on-shore organisations (ONSOs) and off-shore organisations (OFFSOs). The aim was to compare findings from trained emergency staffs’ perceptions of the impact of exercises. The data were retrieved from surveys conducted by the research team in conjunction with exercises. The surveys included staff from the coast guard, sea rescue, police ...

Here we demonstrate how to reconstruct force profiles with an amplitude-modulation AFM operated in in standard tapping mode. Our example is based on the Cypher scanning probe microscope from Asylum Research. The method is based on Sader and Katan’s algorithm, but we have implemented an experimental set-up that allows for robust reconstruction. We discuss the details here.

For decades, whitefish industries in Iceland and Norway have produced similar products and have exported to the same global markets. Nevertheless, there are indications that the Icelandic industry has been more profitable than the Norwegian industry over the same time period. Therefore, this study aims to determine if the two competing industries pursue different marketing and harvesting strategies ...
