Autonomous ROV inspections of aquaculture net pens using DVL
(Peer reviewed; Journal article, 2021)This article presents a method for guiding a remotely operated vehicle (ROV) to autonomously traverse an aquaculture net pen. The method is based on measurements from a Doppler velocity log (DVL) and uses the measured ... -
Couple Relationships Are Associated With Increased REM Sleep—A Proof-of-Concept Analysis of a Large Dataset Using Ambulatory Polysomnography
(Peer reviewed; Report, 2021)Background/Objectives: Rapid Eye Movement (REM) sleep is associated with memory consolidation and several health effects including stress response, mental health, and longevity. Recently, it has been shown that regularly ... -
Effect of diet on molecular relationships between Atlantic cod larval muscle growth dynamics, metabolism, and antioxidant defense system
(Peer reviewed; Journal article, 2022)We studied molecular effects (RNAseq and qPCR) of first feeding prey types (copepods or rotifers/Artemia) on skeletal muscle myogenesis and growth dynamics (proliferation, differentiation), metabolism (glycolysis, ... -
Numerical study of closed rigid fish cages in waves and comparison with experimental data
(Peer reviewed; Journal article, 2021)Closed fish cages have gained increased interest in marine aquaculture. However, knowledge on the seakeeping behaviour of a floating closed cage and the influence of the contained water inside the cage are still limited. ... -
Climate change mitigation effects: How do potential CO2 leaks from a sub-seabed storage site in the Norwegian Sea affect Astarte sp. bivalves?
(Peer reviewed; Journal article, 2021)Carbon capture and storage (CCS) is one of the most promising mitigation strategies for reducing the emissions of carbon dioxide (CO2) to the atmosphere and may substantially help to decelerate global warming. There is an ... -
Inertial torque on a small spheroid in a stationary uniform flow
(Peer reviewed; Journal article, 2021)How anisotropic particles rotate and orient in a flow depends on the hydrodynamic torque they experience. Here we compute the torque acting on a small spheroid in a uniform flow by numerically solving the Navier-Stokes ... -
Constrained Autonomy for a Better Human–Automation Interface
(Chapter; Peer reviewed, 2021)The concept of autonomous or uncrewed ships is not new. Japan investigated remote control of ships in the “Highly reliable intelligent ship” project from 1982 to 1988 (Hasegawa 2004). The rocket launching platform L/P ... -
Overexploitation, Recovery, and Warming of the Barents Sea Ecosystem During 1950–2013
(Peer reviewed; Journal article, 2021)The Barents Sea (BS) is a high-latitude shelf ecosystem with important fisheries, high and historically variable harvesting pressure, and ongoing high variability in climatic conditions. To quantify carbon flow pathways ... -
Large-scale basin testing to simulate realistic oil droplet distributions from subsea release of oil and the effect of subsea dispersant injection
(Peer reviewed; Journal article, 2021)Small-scale experiments performed at SINTEF, Norway in 2011–12 led to the development of a modified Weber scaling algorithm. The algorithm predicts initial oil droplet sizes (d50) from a subsea oil and gas blowout. It was ... -
Atlantic cod (Gadus morhua) embryos are highly sensitive to short-term 3,4-dichloroaniline exposure
(Peer reviewed; Journal article, 2021)3,4-dichloroaniline (3,4-DCA) is one of the most widely produced anilines world-wide, used in plastic packaging, fabrics, pharmaceuticals, pesticides, dyes and paints as well as being a degradation product of several ... -
The effect of white and green LED-lights on the catch efficiency of the Barents Sea snow crab (Chionoecetes opilio) pot fishery
(Peer reviewed; Journal article, 2021)In commercial snow crab (Chionoecetes opilio) fishery, the catch efficiency of the conical pots is important for increasing the profitability of the industry. This study evaluated the effect of adding green and white light ... -
Energetic and Economic Evaluation of Zero-Waste Fish Co-Stream Processing
(Peer reviewed; Journal article, 2021)This study evaluates the possibility of recovery of high-quality valuable fish oil and proteins from fish co-streams by traditional means or a combination of several technologies. A techno-economically feasible and sustainable ... -
Clusters and coherent voids in particle-laden wake flow
(Peer reviewed; Journal article, 2021)Inertial point particles suspended in a two-dimensional unsteady circular cylinder flow at Re = 100 are studied by one-way coupled three-dimensional numerical simulations. The striking clustering pattern in the near-wake ... -
Effects of mine tailing exposure on early life stages of cod (Gadus morhua) and haddock (Melanogrammus aeglefinus)
(Peer reviewed; Journal article, 2021)Mining and processing of minerals produce large quantities of tailings as waste. Some countries, including Norway, allow disposal of mine tailings in the sea. In this study we investigated the impacts of tailings from a ... -
UV treatment in RAS influences the rearing water microbiota and reduces the survival of European lobster larvae (Homarus gammarus)
(Peer reviewed; Journal article, 2021)The rearing environment is important for a stable production of good quality lobster juveniles. By providing an environment excluding pathogens and dominated by mutualistic bacteria, the probability of developing healthy ... -
Warm water treatment increased mortality risk in salmon
(Peer reviewed; Journal article, 2022)Thermal treatment is a controversial method to control sea lice in the Atlantic salmon farming industry. This study aimed to complement the growing evidence base to document the impact of thermal treatments on salmon ... -
Empirical estimation of low-frequency nonlinear hydrodynamic loads on moored structures
(Peer reviewed; Journal article, 2021)Low-frequency (LF) motions of floating structures are commonly modeled as the response of an oscillator to a second-order wave excitation. We present here an empirical method that reliably estimates the oscillators parameters ... -
Sloshing in a rotating liquid inside a closed sea cage for fish farming
(Peer reviewed; Journal article, 2021)Sloshing in a sea cage with a slowly rotating liquid is investigated. The cage is axisymmetric, and the liquid is subjected to a nearly uniform angular velocity about the vertical axis of the cage. Both experimental and ... -
EspyInsideFunction.jl-extracting intermediate results from numerical functions
(Peer reviewed; Journal article, 2022)EspyInsideFunction allows to write software in the Julia programming language Julia (2017) [1] to make the value of variables within a function’s local scope — variables that are neither arguments nor return values, available ... -
An integrated approach for monitoring structural deformation of aquaculture net cages
(Peer reviewed; Journal article, 2021)The majority of present marine finfish production is conducted in flexible net cages which can deform when they are subjected to water movements generated by currents. The ability to monitor net deformation is important ...
