The Celtic Sea (
Four cetacean species occur frequently in the area: minke whale, bottlenose dolphin, short-beaked common dolphin and harbor porpoise.[10] Formerly it held an abundance of marine mammals.[11][12]
The Celtic Sea has a rich fishery with total annual catches of 1.8 million tonnes as of 2007.[9]
Oil and gas exploration in the Celtic Sea has had limited commercial success. The Kinsale Head gas field supplied much of the Republic of Ireland in the 1980s and 1990s.
The seabed under the Celtic Sea is called the Celtic Shelf, part of the 50° the topography is more irregular.[8]
On the North. The Southern limit of the Irish Sea [a line joining St David's Head to Carnsore Point], the South coast of Ireland, thence from Mizen Head a line drawn to a position . On the West and South. A line from the position South to 49°N, thence to latitude 46°30'N on the Western limit of the Bay of Biscay [a line joining Cape Ortegal to Penmarch Point], thence along that line to Penmarch Point. On the East. The Western limit of the English Channel [a line joining Île Vierge to Land's End] and the Western limit of the Bristol Channel [a line joining Hartland Point to St. Govan's Head].

The definition approved by 1974 by the Hydrographer of the Royal Navy for use in Admiralty Charts was "bounded roughly by lines joining Ushant, Land's End, Hartland Point, Lundy Island, St. Govan's Head and Rosslare, thence following the Irish coast south to Mizen Head and then along the 200-metre isobath to approximately the latitude of Ushant."[6]
There are no land features to divide the Celtic Sea from the open Atlantic Ocean to the south and west. For these limits, Holt suggested the 200 fathom (366 m) marine contour and the island of Ushant off the tip of Brittany.
The Celtic Sea takes its name from the Southwest Approaches" to Britain. The need for a common name came to be felt because of the common marine biology, geology and hydrology.[2] It was adopted in France before being common in the English-speaking countries.[2] It was adopted by marine biologists and oceanographers, and later by petroleum exploration firms.[3] It is named in a 1963 British atlas,[4] but a 1972 article states "what British maps call the Western Approaches, and what the oil industry calls the Celtic Sea [...] certainly the residents on the western coast [of Great Britain] don't refer to it as such."[5]
