The Norwegian government has decided that the aquaculture industry shall grow, provided growth is environmentally sustainable. Sustainability scored based on mortality of wild salmonids caused by parasitic salmon lice. Salmon lice infestation pressure traditionally been monitored through catching sea trout and Arctic char using nets or traps trawling after Atlantic postsmolts. However, due to mainland coastline nearly 25 000 km, complementary methods may be used in order give complete...
Storm surges can give rise to extreme floods in coastal areas. The Norwegian Meteorological Institute (MET Norway) produces 120-hour regional operational storm surge forecasts along the coast of Norway based on Regional Ocean Modeling System (ROMS), using a model setup called Nordic4-SS. Despite advances development models and computational capabilities, forecast errors remain large enough impact response measures issued alerts, particular, during strongest events. Reducing these will...
Abstract. An operational ocean and sea ice forecast model, Barents-2.5, is implemented for short-term forecasting at the coast off northern Norway, Barents Sea, waters around Svalbard. Primary parameters are concentration (SIC), surface temperature (SST), currents. The model also provides input data drift modeling of pollutants, icebergs, search-and-rescue applications in Arctic domain. Barents-2.5 has recently been upgraded to include an ensemble prediction system with 24 daily realizations...
Abstract Observations from the past decades have promoted idea of a long-lived anticyclonic vortex residing in Lofoten Basin. Despite repeatedly recorded intense anticyclones, observations cannot firmly decide whether signature is single or succession ephemeral vortices. A persisting for requires some reinvigoration mechanism. Wintertime convection and merging been proposed candidates. We examine Basin dynamics using high-resolution regional ocean model. The model initialized coarser state...
Abstract We consider the Norwegian Meteorological Institute’s system regarding daily forecasts of water level, and warnings possible dangerous level events along coast. The consists three parts, production forecasts, a decision support system, for dissemination to key users general public. Included is brief description forecasting model parallel ensemble prediction an assessment produced by them. Based on models year period we find that they provide sufficiently trustworthy levels purpose at...
Multi-model ensembles for sea surface temperature (SST), salinity (SSS), currents (SSC), and water transports have been developed the North Sea Baltic using outputs from several operational ocean forecasting models provided by different institutes. The individual differ in model code, resolution, boundary conditions, atmospheric forcing, data assimilation. are produced on a daily basis. Daily statistics calculated each parameter giving information about spread of forecasts with standard...

Primary parameters are concentration (SIC), surface temperature (SST), currents. The model also a substantial input drift modeling of pollutants, berg, in search-and-rescue pertinent applications Arctic domain.

The shallow-water equations are often used as a classical simplified ocean model for barotropic dynamics. same can also be to baroclinic dynamics through the reduced-gravity model. Herein, we propose utilise GPU-accelerated simulation framework representing two decoupled models each of and dynamics, use these ensemble prediction short-term drift trajectories in coastal domains. This system complementary current operational systems lightweight tool uncertainty quantification future...
Knowledge about statistics for water level variations along the coast due to storm surge is important utilization of coastal zone. An open and freely available hindcast archive covering Norway adjacent sea areas spanning time period 1979–2022 presented. The model forced by wind stress mean pressure taken from non-hydrostatic NORA3 atmospheric hindcast. A dataset consisting observations more than 90 gauges coasts North Sea Norwegian compiled quality controlled, used assess performance...

A numerical fjord model for the Oslo Fjord in Norway is developed. The built on ROMS system and calculates currents hydrography fjord. In order to receive funding make sure that research will be applied outside of academia, downstream users have defined included. project FjordOs, some end were included throughout project. This caused challenges communication complex modelling issues, but also several benefits. now know more about how results may and, importantly, not applied, modellers got...

A high-resolution hindcast archive around the coast of Norway spanning time period 1979-2022 is presented. The model found to perform well with forcing from NORA3 atmospheric hindcast. Observations water level gauges along coasts North Sea and Norwegian are used assess performance hindcast, which generally be in good agreement. In addition, 100-year return estimates calculated
Plastic pellets in the ocean are becoming an increasing environmental hazard all around globe [1]. Modelling of drift patterns coastal areas is a challenging task due to complex topography causing flow pattern that vary over short distances and during periods time. Due pollution, need for accurate great importance. In this project, numerical model used together with order compute statistical results on where most likely accumulate land high accuracy. The predictions compared observations...
