Caption from Oceanus magazine, Vol. 42, No. 2, Pg. 84:
A WALL OF WATER—The Mid-Atlantic Ridge near the equator is offset by long, deep faults, called fracture zones. A strong deep current flows along and through these fracture zones, almost straight across the South Atlantic. The combination of currents and fracture zones may act as a physical barrier blocking the transport of vent fauna between the North and South Atlantic Oceans—a subsea equivalent of a Berlin Wall.
