Simulating spreading of salmon lice with Ladim (Rapport fra Havforskningen nr. 31 - 2013)

When creating a salmon farm, knowing where salmon lice can spread from that location is of interest. Using ladim (Lagrangian Advection and Diffusion Model) one can get an estimate of this, but the question remains of how a simulation should be done, to get a general spreading field. Specifically, for how long a period should the simulation run. As the regional distribution could depend on the length of the simulations, a period should be found so that the distribution doesn’t change significantly for longer simulations, the hope being that this would capture the general variability around the site.
