Metadata: 2005 Strategic Environmental Assessment SEA6 Technical Report - Sea Mammal Research - Background Information on Marine Mammals (Irish Sea)
Abstract:
This report is a contribution to the Strategic Environmental Assessment (SEA6) conducted by the Department of Trade and Industry (now Department of Energy and Climate Change). Seven marine mammal species are known to occur regularly in the SEA6 area. A relatively small but fairly discrete population of grey seals utilises all but the northwest Irish Sea. Harbour seals are found primarily in the far north of the area. Harbour porpoises are seen year round throughout the area and bottlenose dolphins are present year round off Wales. Minke whales, Risso's dolphins and short-beaked common dolphins are regularly seen in summer mainly in the far south. The report discusses the distribution and abundance of these mammals and their ecological importance. Marine mammals make use of sound for a variety of purposes: finding prey, detecting predators, communication and probably navigation. The offshore oil and gas industry generates underwater noise at every stage of the process: during exploration seismic surveys, drilling, production and decommissioning. The effects of these different sources of underwater noise on marine mammals are discussed. The use of explosives for underwater cutting and demolition during the decommissioning of platforms and installations may pose a serious threat to some marine mammals. The effects of pollution on seals and cetaceans are discussed, including the effects of oil spills. The prevalence of disease among the marine mammal populations is reviewed.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The report was prepared by the Sea Mammal Research Unit, Gatty Marine Laboratory, University of St Andrews 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 haul-out sites and an increasing body of data from satellite telemetry studies. Information on cetacean distribution comes from both dedicated and opportunistic sightings surveys made by a wide spectrum of organisations, some voluntary and some funded by industry and by governmental agencies. There are estimates of abundance only for bottlenose dolphins associated with the Cardigan Bay SAC (213; 95% CI 183-279), and for harbour porpoises in the same area (122; 95% CI 90-165). |
