The Irish Sea (Irish Muir Éireann, English Irish Sea ) separates the islands of Ireland and Great Britain.
It is connected to the south by St George's Channel ( between Ireland and Wales), with the Atlantic Ocean, the north by the North Channel ( between Ireland and Scotland).
The Irish Sea is a spawning area of the North Sea mackerel.
The Isle of Man is located in the middle of the Irish Sea. The volume of the ocean is 2800 km ³ with an average depth of only 52 meters. In the Irish Sea, among others, the radioactively contaminated waste water from the nuclear plant at Sellafield are introduced.
