**Figure 5B-5** depicts a vertical cross section of the Atlantic Ocean along a north-south line. It shows the general form of the layered structure of the Atlantic Ocean (South and North). Arrows portray the density-driven circulation of water masses. Almost all the water masses identified in this investigation originated in a few relatively small regions of the ocean. The sinking of cold dense water at high latitudes drives circulation. These water masses and deep currents also circulate through the other major ocean basins.

The diagram shows:
- The vertical axis represents depth in kilometers (km) from the surface (SFC) down to 4 km.
- The horizontal axis represents latitude from 80°S to 80°N.
- Labels such as **AABW** (Antarctic Bottom Water), **NADW** (North Atlantic Deep Water), **AAIW** (Antarctic Intermediate Water), **NACSW** (North Atlantic Central Surface Water), and **MW** (Mediterranean Water) indicate different water masses.
- Arrows indicate the direction of water movement within these different water masses. For example, the cold dense Antarctic Bottom Water (AABW) flows northward at the bottom of the ocean. Meanwhile, other water masses such as North Atlantic Deep Water (NADW) also flow towards the equator but between different layers.
