The Norwegian Coastal Model (NorKyst800)

The Norwegian Coastal Model (NorKyst800) is a numerical ocean model, which simulates currents, salinity, temperature and sea level. Information on environmental conditions along the coast is extremely valuable in order to assess effects from e.g. oil spills and carrying capacity of aquaculture.

In Norway, a lot of the challenges linked to the coastal zone require detailed information on environmental conditions such as currents, salinity and temperature. The NorKyst800m model is capable of producing realistic scenarios of currents and other environmental conditions along the coast and inshore in the largest fjords, both for the past and the future. The NorKyst800 model may also be applied to quantify the consequences of management decisions, for instance related to construction of hydroelectric power stations or impacts associated with eutrophication or dispersion of diseases.

Safeguard

If a serious accident occurs offshore along the Norwegian coast, the NorKyst800 model is able to provide vital information on the environmental conditions for the relevant time and location. These results can potentially be applied as input to models describing dispersion of oil or drifting objects realistically, near-shore and within the largest fjords. In addition, dispersal of harmful algae and salmon lice adjacent to fish farms may be estimated similarly.

To be able to quantify carrying capacity for the aquaculture, it is important with information on environmental conditions on a regional scale. This is also valid for different species related to mapping of nature types and for assessments associated with the Water Framework Directive.

Models

Models are by definition simplified representations of nature. Still they can give us valuable information about the physical, biological and population dynamic processes in the ocean. And in combination models can help us to gain insight and quantify the dynamics of the complex ecosystems.
