The English Channel, also called simply the Channel, is an arm of the Atlantic Ocean that separates Southern England from northern France and links to the southern part of the North Sea by the Strait of Dover at its northeastern end. It is the busiest shipping area in the world.
It is about 560 km (350 mi) long and varies in width from 240 km (150 mi) at its widest to 34 km (21 mi) in the Strait of Dover. It is the smallest of the shallow seas around the continental shelf of Europe, covering an area of some 75,000 km2 (29,000 sq mi).
There are several major islands in the Channel, the most notable being the Isle of Wight off the English coast, and the Channel Islands, British Crown dependencies off the coast of France.
The Channel acts as a funnel that amplifies the tidal range from less than a metre as observed at sea to more than 6 metres as observed in the Channel Islands, the west coast of the Cotentin Peninsula and the north coast of Brittany.
