Suppose we could take the Atlantic Ocean north of the equator and divide it into two compartments along a north-south line (for example, if sea level were much lower and the Mid-Atlantic Ridge was mergent along its length).
What would happen to the North Atlantic Gyre? a) The gyre would grind to a halt because its north and south currents are blocked.
b) The Mid-Atlantic Ridge barrier would turn equatorial currents north and northern boundary currents south, resulting in two gyres, one on each side.
c) The ridge would cause surface water to sink as it piles up against the barrier and has nowhere else to go.
d) The ridge would have almost no effect, and the currents would just go over or around it.
e) The ridge would cause deep water upwelling as the currents strike the barrier.
