The Celtic Sea is the area of the Atlantic Ocean off the southern coast of Ireland bounded to the north by Saint George’s Channel; other limits include the Bristol Channel, the English Channel, and the Bay of Biscay, as well as adjacent portions of Wales, Cornwall, and Brittany.
The southern and western boundaries are delimited by the continental shelf, which drops away sharply.
The Isles of Scilly are an archipelago of small islands in the sea.
