2004 Strategic Environmental Assessment SEA5 Technical Report - Marine mammals (North Sea)

Abstract

This report is a contribution to the Strategic Environmental Assessment (SEA5) conducted by the Department of Trade and Industry (now Department of Energy and Climate Change). Eight marine mammal species are known to occur regularly in this area: grey seal, harbour seal, harbour porpoise, white-beaked dolphin, bottlenose dolphin, Atlantic white-sided dolphin, killer whale, and minke whale. Long-finned pilot whales and Risso's dolphins are regularly seen in waters around Shetland. There are occasional at-sea records of at least a further five cetacean species (humpback whale, fin whale, sperm whale, striped dolphin and short-beaked common dolphin) and four pinniped species (hooded seal, bearded seal, ringed seal and walrus).

Lineage

Report prepared by the Sea Mammal Research Unit, St Andrews University as part of the UK Department of Energy and Climate Change's Offshore Energy Strategic Environmental Assessment programme. There is extensive information on the distribution and abundance of grey and harbour seals around Britain from annual aerial surveys of breeding colonies and from satellite telemetry studies. There is also extensive information on cetacean distribution in the North Sea from a number of summer sightings surveys (SCANS-94, NASS-89, NILS-95). Estimates of abundance are available from these surveys for some species. There are also many records from year-round surveys by the European Seabirds at Sea Consortium (ESAS) since 1979, from cetacean observations made during seismic surveys from 1996, and sightings by voluntary observers compiled by the Sea Watch Foundation. Acoustic studies using towed hydrophone arrays, pop-up sonobuoys and the US Navy's passive underwater monitoring system (SOSUS) have been used to monitor the distribution and in some cases the density of fin whales, sperm whales and dolphins in the wider area (Swift et al 2002).
