Major Straits of the World
Straits of Atlantic Ocean:
- Hudson Strait links the Atlantic Ocean and Labrador Sea to Hudson Bay in Canada.
- This strait lies between Baffin Island and Nunavik, with its eastern entrance marked by Cape Chidley in Newfoundland and Labrador and Resolution Island off Baffin Island.
- The strait is about 750 km long with an average width of 125 km, varying from 70 km at the eastern entrance to 240 km at Deception Bay.
- The strait was named after Henry Hudson who explored it in 1610 in the ship Discovery.
Straits of Florida
- The Straits of Florida is a strait located south-southeast of the North American mainland, between the Gulf of Mexico and the Atlantic Ocean, and between the Florida Keys (U.S.) and Cuba.
- It is 150 km wide at the narrowest point between Key West and the Cuban shore, and has been sounded to a depth of 6,000 feet.
- The strait carries the Florida Current, the beginning of the Gulf Stream, from the Gulf of Mexico.
- The Yucatán Channel or Straits of Yucatán is a strait between Mexico and Cuba.
- It connects the Yucatán Basin of the Caribbean Sea with the Gulf of Mexico.
- It is just over 200 kilometres wide and nearly 2,800 metres deep at its deepest point near the coast of Cuba.
- The North Channel is the strait between north-eastern Northern Ireland and south-western Scotland.
- It begins north of the Isle of Man, where the Irish Sea ends, and runs north-west into the Atlantic Ocean.
- The North Channel connects the Irish Sea with the Atlantic Ocean and is part of the marine area officially classified as the “Inner Seas off the West Coast of Scotland” by the International Hydrographic Organization (IHO).
Strait of Dover
- The Strait of Dover is the strait at the narrowest part of the English Channel, marking the boundary between the Channel and the North Sea, separating Great Britain from continental Europe.
- The shortest distance across the strait, at approximately 32 kilometres, is from the South Foreland, northeast of Dover in the English county of Kent, to Cap Gris Nez, a cape near to Calais in the French département of Pas-de-Calais.
- Until 1994 ferries provided the only route across it except for air transport.
- The Channel Tunnel now provides an alternative route, crossing beneath the strait at an average depth of 45 m below the seabed.
