Close to the North Atlantic continental shelf is a group of shallow underwater plateaus called Grand Banks. This area is unique because the cold Labrador Current mixes with the warm waters of the Gulf Stream. The mixing of the streams and the shape of the ocean bottom lifts nutrients to the surface, helping to create one of the richest fishing grounds in the world but it is also the cause of violent storms that happen in the best fishing zone of this area: the well-known Flemish Cap of The Perfect Storm. Swordfish is a board game on the fishing and commerce of swordfish.
