North and South Atlantic?

Question

At what point does the North Atlantic Ocean become the SOUTH Atlantic Ocean ( and Vice versa)?

Is it the Equator?, or some other line of latitude?

Answer 1

The equator, since it is the one which divides the earth into the northern and southern hemispheres.

Answer 2

Atlantic is a beautiful ocean with the much sought after 'hour glass' figure unlike the rotund Pacific & Indian oceans.

Between 'Cape Palmas' (4d 24' N / 8d 10' E) in Liberia and 'Cape (or Cabo?) de Sao Roque' (5d 12' S / 36d 20' W) in Brazil it has minimum breadth at 1/8th of Earth's circumference (arc distance 45d 28' 16.15" or 2728.27 nautical miles / 5047km). Hence that is the line of demarcation.

Answer 3

im pretty sure its the equator since its at 0 degrees north and south latitude
