Assimilation of real-time measurements with an individual-based model for estimation of geographical distribution and abundance of Norwegian herring
Kelly, Cian (Doctoral theses at NTNU;2023:73, Doctoral thesis, 2023)The fishing industry faces both challenges and opportunities in the wake of the green transition in fisheries. Challenges stem from attempts to reduce the carbon footprint of activity while simultaneously providing food ... -
Capturing big fisheries data: Integrating fishers’ knowledge in a web-based decision support tool
Kelly, Cian; Michelsen, Finn Are; Reite, Karl Johan; Kolding, Jeppe; Varpe, Øystein; Prytz Berset, Are; Alver, Morten (Peer reviewed; Journal article, 2022)There is increasing interest in utilizing fishers’ knowledge to better understand the marine environment, given the spatial extent and temporal resolution of fishing vessel operations. Furthermore, fishers’ knowledge is ... -
Data assimilation with SINMOD
Alver, Morten; Michelsen, Finn Are (Research report, 2015)Data assimilation is the process of using measured data to correct the state of a mathematical model. This report documents the data assimilation process implemented in the ocean model system SINMOD, and the tests that ... -
Data-driven Current Model as Part of a Digital Twin for Submarine Drones
Bing, Carsten Antonio (Master thesis, 2022)Undervannsdroner har historisk sett ikke vært i stand til å bruke fulle havsimuleringer på grunn av at de krever omfattende prosessorkraft. Dette prosjektet utvikler en enkel datadrevet havmodell som simulerer data fra ... -
Dynamic behaviour of an HMR pre-combustion gas power cycle
Zhao, Lei; Michelsen, Finn Are; Foss, Bjarne Anton; Aasen, Knut I (Journal article; Peer reviewed, 2010)This paper explores dynamics for control design of a Hydrogen Membrane Reformer (HMR) pre-combustion gas power cycle. For this type of reforming to be competitive to power generation with carbon ... -
An ensemble modelling approach for spatiotemporally explicit estimation of fish distributions using data assimilation
Kelly, Cian; Michelsen, Finn Are; Alver, Morten Omholt (Journal article; Peer reviewed, 2023)This article presents a novel method for estimating large scale spatiotemporal distribution patterns of fish populations modelled at the individual level. A single realization of an individual-based model calibrated on ... -
Estimation of fish catch potential using assimilation of synthetic measurements with an individual-based model
Kelly, Cian; Michelsen, Finn Are; Alver, Morten Omholt (Journal article; Peer reviewed, 2023)A large fraction of costs in wild fisheries are fuel related, and while much of the costs are related to gear used and stock targeted, search for fishing grounds also contributes to fuel costs. Lack of knowledge on the ... -
Multiscale modelling of cage effects on the transport of effluents from open aquaculture systems
Broch, Ole Jacob; Pascal, Klebert; Michelsen, Finn Are; Alver, Morten (Peer reviewed; Journal article, 2020)Most Atlantic salmon mariculture operations use open sea cages for the grow out phase. The ultimate fate and effects of the effluents and the possibilities of disease transfer between fish farms are major concerns for ... -
Tuning and Development of an Individual-Based Model of the Herring Spawning Migration
Kelly, Cian; Michelsen, Finn Are; Kolding, Jeppe; Alver, Morten (Peer reviewed; Journal article, 2022)Norwegian spring spawning herring is a migratory pelagic fish stock that seasonally navigates between distant locations in the Norwegian Sea. The spawning migration takes place between late winter and early spring. In this ...
