It is called the North Atlantic Deep Water.
Yes, Atlantic deep water is warmer and less dense than the Antarctic bottom water, so it flows on top.

a surface current
When the North Atlantic ocean meets the Antarctic bottom water Hurricanes form(:
Antarctic bottom water is colder than either the Antarctic intermediate water or the Atlantic deep water. The North Atlantic bottom water doesn't flow far enough south to intermix with the Southern Ocean.
Sargasso Sea. Sargasso Sea is distinctive for its deep blue color and exceptional clarity, with underwater visibility of up to 200 feet (61 m).The Sargasso Sea is a region in the Gyre in the middle of the North Atlantic Ocean. It is bounded on the west by the Gulf Stream; on the north, by the North Atlantic Current; on the east, by the Canary Current; and on the south, by the North Atlantic Equatorial Current. This system of ocean currents forms the North Atlantic Gyre.
The Antarctic Bottom Water, North Atlantic Deep Water, and Antarctic Intermediate Water are three density currents that form in polar regions.
Three major surface currents are the Gulf Stream in the North Atlantic Ocean, the Kuroshio Current in the North Pacific Ocean, and the Antarctic Circumpolar Current in the Southern Ocean. These currents play a significant role in distributing heat and nutrients around the globe.
The arrangement of water masses in the southern Atlantic Ocean from the surface to the bottom is Antarctic Intermediate water, north Atlantic deep water, and the Antarctic bottom water. The location where water flow uninterrupted between the Pacific, the Atlantic, and the Indian Oceans is in the southern ocean.
The global current conveyor belt begins in the North Atlantic Ocean, where warm water from the Gulf Stream moves northward to the Arctic. This warm water eventually cools and sinks in the Labrador Sea, starting a deep current that travels southward along the ocean floor.
One example of a density current in the northern hemisphere is the North Atlantic Deep Water (NADW). It is a deep, cold, and dense water mass that forms in the North Atlantic Ocean due to cooling and increased salinity, sinking to the ocean floor and flowing southward along the ocean bottom.
