Flemish Cap

The Flemish Cap is an area of shallow waters in the north Atlantic Ocean centered roughly at 47° north, 45° west or about 350 miles (560 km) east of St. John's, Newfoundland and Labrador.
The shallow water is caused by a wide underwater plateau covering an extended area of 12,000 square miles (42,000 km²). Depths at the cap range from approximately 400 feet (122 m) to 2,300 feet (700 m).
