A nonparametric algorithm to model movement between polygon subdomains in a spatially explicit ecosystem model
Abstract: Many modern spatially explicit ecosystem models use modelling subdomains of different ... shape and size (‘polygons’) to resolve space, and movement of biomass between them forms an important ... part of the modelling effort. In marine applications, a flow field grid describing the water movement ... usually forms the basis for movement of passive or nearly passive biomass. Grid-based advection algorithms ...
