The Aghulas Bank, from Portuguese for Cape Agulhas, Cabo das Agulhas, “Cape of Needles”) is a broad, shallow part of the southern African continental shelf which extends up to 250km (160mi) south of Cape Agulhas before falling steeply to the abyssal plain. It is the ocean region where the warm Indian Ocean and the cold Atlantic Ocean meet. This convergence leads to treacherous sailing conditions, accounting for numerous wrecked ships in the area over the years. However the meeting of the oceans here also fuels the nutrient cycle for marine life, making it one of the best fishing grounds in South Africa. (Source Wikipedia)
