The Gulf of Mexico was a gulf on Earth. This was an extension of the Atlantic Ocean, with the United States of America, Cuba, and Mexico having coastlines on this Gulf.
In an alternate 1944, the gulf 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 Golf von Mexico (Gulf of Mexico). (ENT: "Storm Front", "Storm Front, Part II")
In the 21st century, Lieutenant John Kelly would tease Rose Kumagawa about her claim of seening an UFO over the Gulf. He would tell her it was a meteor or a piece of the space station Mir. In one of the last logs of the Ares IV, Kelly mentioned that he had a remembrance of this. (VOY: "One Small Step")
In the 22nd century, the future Commander Charles Tucker III would drive his first car out to Chatkin Point. He would park at the shoreline, feel the ocean breeze coming off the Gulf, and spend time with his girlfriend staring at the moon. (ENT: "Precious Cargo")
Tucker would often go swimming in the Gulf, sometimes inviting a girlfriend named Lisa. He would often tell T'Pol of his desire to show her some of the beaches of the Gulf. (ENT: "The Crossing")
In March 2153, the strait between Florida and Cuba, which connected the Gulf to the Atlantic, was attacked during the Xindi incident. (ENT: "The Expanse")
A 21st century-era political map of Earth was stored in the USS Enterprise's library computer in 2254. The location of the Gulf of Mexico was labeled on this map. This map was among the materials viewed by the Talosians when they scanned the Enterprise computer. (TOS-R: "The Cage")
While discussing the prospect of leaving USS Voyager to live among a group of Humans settled in the Delta Quadrant, Chakotay reminded himself that he could never do it knowing that he would be giving up such prospects as seeing the sunrise over the Arizona desert, or swimming in the Gulf of Mexico on a summer's day. (VOY: "The 37's")
The map used in the remastered "The Cage" was a Central Intelligence Agency map published in September 2008. The ice shelfs of Antarctica were masked with black ink. [1]
Retroactive continuity: The Gulf of Mexico was seen on a 20th century-era map of the northern hemisphere. This map was among the materials viewed by the Talosians when they scanned the Enterprise computer. These maps were from educational texts available at the time of filming, 1964.
