The Celtic Sea is a part of the Atlantic Ocean off the south coast of Ireland. It locates to the east of Saint George’s Channel. However, the additional boundaries also include the Bristol Channel, the English Channel, and the Bay of Biscay. It is nearby parts of Wales, Cornwall, and Brittany. The Sea is to the southwest of England. The continental shelf, which descends rapidly to the south and west, defines the southern and western limits. The Isles of Scilly are a group of small islands in the middle of the sea.
Why is it called the Celtic Sea? The Celtic Sea gets its name from the Celtic heritage of the north and east surrounding lands. E. W. L. Holt offered the name at a meeting of fisheries experts from the United Kingdom, France, and Ireland in Dublin in 1921. The northern area of this sea considers part of Saint George’s Channel. While the southern portion is deemed an undefined part of Great Britain’s “Southwest Approaches.” The idea for a common name arose as a result of the area coming from marine biology, geology, and hydrology.
Where is the Celtic Sea deep? Trevose Head locate in Cornwall, and its northern area is nearly 84 kilometers from the Welsh coast of Pembrokeshire. The site creates a depression on the seafloor when compared to the surrounding area, with water depths ranging from 100 to 200 meters.
