Celtic Sea

The Celtic Sea is a big part of the ocean.

It sits near the coast of Ireland. Many lands surround this sea. Small islands sit in the water too.

Many animals live here. You might see a minke whale. You might see a dolphin. There are also small sea creatures.

Some people look for oil under the sea. This can be hard to do. The water is very deep there.

Wind can also help make power here. Large fans float on the water. This uses the wind to make energy.

It is a busy and wild place.

The Celtic Sea is a part of the Atlantic Ocean.

It sits near the coast of Ireland. Many lands surround this sea. These include parts of Wales, England, and France. The sea gets its name from the Celtic people. They lived on the lands nearby.

Experts wanted one common name for this area. They chose it because the water and rocks are similar. The bottom of the sea is called the Celtic Shelf. It is part of a big shelf under the ocean. In some spots, sand ridges sit on the bottom. These ridges formed when the sea level was lower.

Many animals live in these waters. You might see a minke whale. You might also see dolphins or a harbor porpoise. In 2007, people caught 1.8 million tonnes of fish here.

People also look for power in the sea. The water is too deep for fixed wind fans. But, big wind farms can float on the water. These use wind to make power. Some companies also look for oil and gas. The Kinsale Head gas field once gave much gas to Ireland.

The Celtic Sea is a large area of the Atlantic Ocean.

It sits near the southern coast of Ireland. Many different lands surround this sea. These include parts of Wales and Cornwall. It also sits near Devon and Brittany. The sea is bounded by several channels. These are the Saint George's Channel and the English Channel. The Bristol Channel and the Bay of Biscay also form its limits.

The way the sea works involves its unique shape and floor. The bottom of the sea is called the Celtic Shelf. This is part of the larger continental shelf of Europe. In the northeast, the depth is between 100 and 200 meters. The floor has sand ridges that point toward the southwest. These ridges were made by tides when the sea level was lower. Between these ridges are deep areas called troughs.

People did not always call this area the Celtic Sea. In 1921, a man named E. W. L. Holt proposed the name. He suggested it at a meeting of experts in Dublin. Before this, the area had many different names. Some called it the Southwest Approaches to Great Britain. Experts wanted one name for the whole area. This was because the biology and the water were so similar.

Many living things call this sea home. In 2007, the total catch of fish was 1.8 million tonnes. You can often find four types of sea mammals here. These are the minke whale and the bottlenose dolphin. You might also see the short-beaked common dolphin. The harbor porpoise is also a frequent visitor.

Humans also use the sea for energy and resources. The Kinsale Head gas field supplied much of Ireland's gas. This happened during the 1980s and the 1990s. The water is too deep for fixed wind turbines. However, there is potential for 50 GW of floating wind farms. A company called TotalEnergies plans a project for 100 MW.

The Celtic Sea is a specific area of the Atlantic Ocean. It is located off the southern coast of Ireland. This sea is surrounded by several different landmasses and water channels. To the north, it is bounded by Saint George's Channel. Other limits include the Bristol Channel, the English Channel, and the Bay of Biscay. It also sits near parts of Wales, Cornwall, Devon, and Brittany. The southern and western boundaries are defined by the continental shelf. This is a part of the ocean where the land continues underwater before dropping away sharply.

The seabed of this region is known as the Celtic Shelf. This shelf is part of the larger continental shelf of Europe. In the northeast, the water depth stays between 100 and 200 meters. As you move toward Saint George's Channel, the depth increases. In other areas, the floor features sand ridges that point toward the southwest. These ridges are separated by troughs, which are deeper areas in the seabed. These ridges were formed by tidal effects when the sea level was much lower than it is today. South of 50°N, the topography of the seafloor becomes more irregular.

Historically, people did not always use the name "Celtic Sea." Before this name was adopted, the northern part was seen as part of Saint George's Channel. The southern part was often called the Southwest Approaches to Great Britain. In 1921, E. W. L. Holt proposed the name "Celtic Sea" during a meeting in Dublin. This meeting included fisheries experts from Great Britain, France, and the Republic of Ireland. They wanted a common name because the marine biology, geology, and hydrology were similar across the area. The name was adopted in France before it became common in English-speaking countries.

Different organizations use different rules to define the sea's boundaries. In 1974, the UK Hydrographer of the Navy approved a definition for British Admiralty Charts. This definition uses lines joining places like Ushant, Land's End, Lundy Island, and Rosslare. It follows the Irish coast down to Mizen Head. It then follows a 200-metre isobath, which is a line showing points of equal depth. The International Hydrographic Organization uses a different set of limits. Their definition includes specific lines connecting points like St David's Head, Carnsore Point, and Penmarch Point.

The Celtic Sea is a very productive area for marine life. As of 2007, the total annual catches of fish reached 1.8 million tonnes. This area is also home to several species of cetaceans, which are marine mammals. You can frequently find minke whales and bottlenose dolphins here. Short-beaked common dolphins and harbor porpoises are also frequent visitors. While the sea once held an even greater abundance of marine mammals, it remains a rich environment for many species.

Humans have also looked to the Celtic Sea for energy resources. For a time, the Kinsale Head gas field was very important. It supplied much of the demand for gas in Ireland during the 1980s and 1990s. While oil and gas exploration has had limited commercial success, there is new interest in wind energy. The water is too deep for fixed wind turbines that are attached to the floor. However, the area has the potential for 50 GW of floating wind farms. One company, TotalEnergies, is already planning a project with almost 100 MW of capacity.

The Celtic Sea connects many different geographic and scientific systems. It serves as a bridge between the English Channel, the Bristol Channel, and the Bay of Biscay. It also links the Irish Sea to the open Atlantic Ocean. Because of its unique geology and water patterns, it is a key area for oceanographers and marine biologists. The sea's characteristics help scientists understand how tides and currents work across the European continental shelf.
