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. \r\n\r\nMarine 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.\r\n\r\nThe 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.", "includedInDataCatalog": { "@id": "http://portal.medin.org.uk/portal/json-ld/catalog.jsonld" }, "distribution": [ { "@type": "DataDownload", "name": "Strategic Environmental Assessment (SEA) data portal", "contentUrl": "http://www.bgs.ac.uk/data/sea/home.html" } ], "temporalCoverage": "2005-01-01", "keywords": [ { "@type": "DefinedTerm", "identifier": "http://vocab.ndg.nerc.ac.uk/term/N010/0", "name": "NDGO0001" }, { "@type": "DefinedTerm", "identifier": "http://vocab.ndg.nerc.ac.uk/term/P021/64/CEBH", "name": "Cetacean behaviour" }, { "@type": "DefinedTerm", "identifier": "http://vocab.ndg.nerc.ac.uk/term/P021/64/CEMP", "name": "Cetacean morphology and physiology" }, { "@type": "DefinedTerm", "identifier": "http://vocab.ndg.nerc.ac.uk/term/P021/64/CETA", "name": "Cetacean abundance" }, { "@type": "DefinedTerm", "identifier": "http://vocab.ndg.nerc.ac.uk/term/P021/64/IACT", "name": "Industrial activity" }, { "@type": "DefinedTerm", "identifier": "http://vocab.ndg.nerc.ac.uk/term/P021/64/IDIS", "name": "Industrial discharges" }, { "@type": "DefinedTerm", "identifier": "http://vocab.ndg.nerc.ac.uk/term/P021/64/SEBH", "name": "Seal behaviour" }, { "@type": "DefinedTerm", "identifier": "http://vocab.ndg.nerc.ac.uk/term/P021/64/SEMP", "name": "Seal morphology and physiology" }, { "@type": "DefinedTerm", "identifier": "http://vocab.ndg.nerc.ac.uk/term/P021/64/FOCA", "name": "Seal abundance" }, { "@type": "DefinedTerm", "name": "Species distribution" }, { "@type": "DefinedTerm", "identifier": "http://vocab.ndg.nerc.ac.uk/term/L131/3/CR", "name": "crust" }, { "@type": "DefinedTerm", "identifier": "http://vocab.ndg.nerc.ac.uk/term/L131/3/SD", "name": "sediment" } ], "spatialCoverage": { "@type": "Place", "geo": { "@type": "GeoShape", "box": "51.7 -6 55.3 -4" }, "additionalProperty": [ { "@type": "PropertyValue", "propertyID": "http://www.opengis.net/def/crs/OGC/1.3/CRS84", "value": "urn:ogc:def:crs:EPSG:4326" } ] }, "maintainer": [ { "@type": "Organization", "name": "British Geological Survey (BGS)", "description": "custodian", "email": "offshoredata@bgs.ac.uk", "telephone": "+44 (0)131 667 1000", "address": { "@type": "PostalAddress", "streetAddress": "Murchison House, West Mains Road", "postalCode": "EH9 3LA", "addressLocality": "Edinburgh", "addressCountry": "UK" } } ], "producer": [ { "@type": "Organization", "name": "Department for Energy and Climate Change (DECC)", "description": "originator", "email": "enquiries@decc.gsi.gov.uk", "telephone": "+44 0300 060 4000", "faxNumber": "+44 (0) 1823 284077", "address": { "@type": "PostalAddress", "streetAddress": "Admiralty Way", "postalCode": "SW1A 2HD", "addressLocality": "London", "addressCountry": "UK" } } ], "publisher": [ { "@type": "Organization", "name": "British Geological Survey (BGS)", "description": "pointOfContact", "email": "offshoredata@bgs.ac.uk", "telephone": "+44 (0)131 667 1000", "faxNumber": "+44 (0)131 668 4140", "address": { "@type": "PostalAddress" } } ], "creator": [ { "@type": "Organization", "name": "Department for Energy and Climate Change (DECC)", "description": "originator", "email": "enquiries@decc.gsi.gov.uk", "telephone": "+44 0300 060 4000", "faxNumber": "+44 (0) 1823 284077", "address": { "@type": "PostalAddress", "streetAddress": "Admiralty Way", "postalCode": "SW1A 2HD", "addressLocality": "London", "addressCountry": "UK" } } ], "sdPublisher": { "@type": "Organization", "url": "https://portal.medin.org.uk/portal/", "name": "Marine Environmental Data and Information Network (MEDIN)", "description": "The MEDIN portal contains information about 19493 marine datasets from over 600 UK organisations.
