You might be hearing about the gulf off the coast of the U.S. and Mexico. Here's what to know about the body of water the size of Alaska.

Chevron Corp. has begun using “Gulf of America” instead of “Gulf of Mexico” in its earnings materials after President Donald Trump ordered the US to rename it.

When Google announced it was complying with US President Donald Trump’s executive order to rename the Gulf of Mexico to the Gulf of America, many Mexicans responded with a laugh and a long, exhausted sigh.

For us it is still the Gulf of Mexico, and for the entire world it is still the Gulf of Mexico,” President Claudia Sheinbaum said.

But Mexico argues the U.S. cannot legally change the Gulf's name because the United Nations Convention on the Law of the Sea dictates that an individual country's sovereign territory only extends up to 12 nautical miles out from the coastline.

Google said it would follow the Trump administration in renaming the Gulf of Mexico once the new name is updated in government sources.

The change will only be visible to U.S. users. Those in Mexico will still see “Gulf of Mexico,” while those in the rest of the world will see both names on the map.

"As directed by the President, the Gulf of Mexico will now officially be known as the Gulf of America," the Interior Department stated in a statement last week. Google responded by noting that the change complies with its longstanding policy of aligning map labeling with updates in official government databases.

The Gulf of Mexico is now officially the Gulf of America in the U.S. It is far from the first time a landform or town has changed names.

President of Mexico Claudia Sheinbaum says her country is reaching out to Google about its Maps change and is suggesting additional revisions of its own.

The federal government, including the military, is changing the name on maps to "Gulf of America." Even Google suggested it would make the change.
