Beaufort's Dyke is a natural glacial formed trench within the North Channel between Northern Ireland and Scotland. The dyke is 50 km (30 miles) long, 3.5 km (2 miles) wide and 200 m (700 ft) - 312 metres (1,024 ft) deep. The Dyke is one of the deepest areas of the European continental shelf.[1]

The trench is recorded in 1856 as having been discovered "some years ago" by a Captain Beechey.[2]
