(covers information from an alternate timeline)
The Atlantic Ocean was an ocean on Earth, second in size after the Pacific. Due to its great size, political maps divided the ocean into the North Atlantic Ocean and the South Atlantic Ocean, with the equator being the border between the two regions. Four continents - Europe, Africa, South America, North America - had coastlines on this ocean. An underwater mountain range, the Mid-Atlantic Ridge, bifurcated the ocean floor.

In an alternate 1944, after conquering England, the forces of Nazi Germany crossed the Atlantic and invaded the northeastern United States. The ocean itself was labeled on the map of the United States of America that showed the progress of the Nazi's campaign on the North American continent. It was described there as Atlantischen Meer (Atlantic Sea). (ENT: "Storm Front", "Storm Front, Part II")
In the late 20th and early 21st centuries, the cruise liner RMS Queen Elizabeth 2 ferried passengers across the Atlantic between the continents of Europe and North America. One of these passengers was Ralph Offenhouse. (TNG: "The Neutral Zone")
A 21st century-era political map of Earth was stored in the USS Enterprise's library computer in 2254. The location of the North Atlantic Ocean and South Atlantic Ocean were labeled on this map. This map was among the materials viewed by the Talosians when they scanned the Enterprise computer. (TOS-R: "The Cage")
Background info Edit
Retroactive continuity Edit
An illustration of the Battle of Hampton Roads, a naval engagement in the American Civil War, was stored in the USS Enterprise's library computer. As well, a 20th century-era political map of the North Atlantic Ocean was stored in the USS Enterprise's library computer in 2254. The map depicted the Arctic Circle, with Atlantic continents North America and Europe, and part of Africa.
