Google and Apple Maps have officially updated the Gulf of Mexico to appear as the Gulf of America for users within the United States to be in alignment with an executive order President Donald Trump signed on his first day in office.

Google announced after the Jan. 20 order it would make the change based on "a longstanding practive of applying name changes when they have been updated in official government sources. Apple followed suit. According to a statement from Google on its blog The Keyword, people using Maps in the U.S. will see "Gulf of America," while people using it in Mexico will continue to see "Gulf of Mexico" and everyone else will see both names with "Gulf of Mexico" listed first and "Gulf of America" below in parenthesis.

"The names you see in the Maps app are based on your country location, which is determined by information from your phone's operating system (e.g., iOS and Android), including your SIM, network and locale. If you're using Google Maps on the web, the names are based on the region you select in your Search settings or your device's location, if you haven't selected one," the statement said.

"In common usage," according to the summary report on the body of water from the U.S. Geological Survey, which runs the Geographic Names Inforamtion System (GNIS), a database of more than 1 million geographic features in the U.S. that Google uses to inform Maps, "the term 'Gulf Coast' refers to the continuous portion of the coast running from Cape Sable, Florida, to the northern tip of the Yucatan Peninsula; in geographic usage it extends east from and to include the Florida Keys to the northerly sides of the Keys there." With an average depth of 5,300 feet, it "is a major body of water bordered and nearly landlocked by North America with the Gulf's eastern, northern and northwestern shores in the U.S. and its southwestern and southern shores in Mexico. Bordered by Cuba on the southeast, it connects to the Atlantic Ocean via the Florida Straits between the U.S. and Cuba, and the Caribbean Sea via the Yucatan Channel between Mexico and Cuba." It spans over 1,700 miles of U.S. coastline.

The Gulf has had many names in the past, though evidence of it being widely coined Gulf of Mexico is in world maps since before either Mexico or the U.S. was a country, based on the Aztecs, and a future president has the authority to change it again, similar to how Trump is now reversing former President Barack Obama's renaming of a mountain in Alaska from Mount McKinley to Denali.

"Variant names" in the past have included numerous renditions, based in English, Spanish and other languages, of Gulf of Mexico; in addition to Bay of Mexico and Bay of Newe Spain in a GIS dataset provided by MyTampa.Gov concerning subdivisions; Mar Di Florida by the federal administration in a state by state guide series published by various publishers, in the late 1930s and 1940s, with each book studying and describing each state's "history, natural endowments and special interests"; and Mexicanska Wiken by the U.S. Post Office in 1877, among others.

State Rep. Stephen Holland, a Democratic lawmaker from Mississippi, introduced a bill to change the Gulf's name to be of America within the state in 2012, though after garnering widespread attention he said it was satirical.

This is also not the only body of water to earn contention over its name. Where Iran and much of the world call the body of water south of the country the Persian Gulf, Saudi Arabia and other Arab nations say it's the Arabian Gulf. Closer to home, while the Rio Grande, as deemed from those living to its north in Texas and the U.S., is considered the Río Bravo in Mexico.
