Sammenligning af iPCoD og DEPONS-modellerne til simulering af populationseffekter af støj på marsvin
Der findes to forskellige modelleringsværktøjer til vurdering af, hvordan støj fra konstruktion af havvindmøller kan påvirke marsvin: iPCoD (Interim Po- pulation Consequences of Disturbance) og DEPONS (Disturbance Effects of Noise on the Harbour Porpoise Population in the North Sea) modellerne.
