Irish Sea

The Irish Sea is a 46,007 km2 body of water that separates Ireland and Great Britain. It is 200 km wide at its greatest point and narrows to 75 km, with a total water volume of 2,430 km3. The sea has undergone significant changes over the last 20,000 years due to the last glacial period. It is of economic importance for trade, shipping, and power generation, with annual traffic between Great Britain and Ireland exceeding 12 million passengers and 17 million tonnes of traded goods. The sea is connected to the North Atlantic through the North Channel and St George's Channel, and is composed of a deeper channel on its western side and shallower bays to the east.learn more on wikipedia
