The maps that represent the porpoises’ food distribution in the DEPONS model have been extended further north and west to also include Moray Firth off the coast of Scotland. This makes it possible to evaluate how noise from wind farm construction will affect the porpoise population in this region.

The maps were extended by merging an existing maps of the porpoise distribution in Moray Firth with similar maps for the North Sea. Presence of porpoises is used as a proxy for food availability in both areas.
