When did the Antarctic ocean become known as the Southern Ocean?

1999
Soon after, the National Oceanic and Atmospheric Administration (NOAA) recognized the body of water as the fifth ocean in 1999 after the Board of Geographic Names approved the title, “Southern Ocean,” reports Paulina Firozi for the Washington Post.

When was the Southern Ocean added?

It’s a driving force behind the global circulation system called the conveyor belt, which moves warm waters all over the planet. In 1999, the U.S. Board of Geographic Names approved the name Southern Ocean.

Was the Southern Ocean once called the Antarctic Ocean?

But, now the National Geographic Society has demarcated a fifth ocean — Southern Ocean. Previously also called Antarctic Ocean informally, this body of water encircling the coldest continent has long been recognised by scientists, but due to a lack of international consensus, it was never officially acknowledged.

Why Antarctic Ocean is called Southern Ocean?

The Southern Ocean, also known as the Antarctic Ocean, comprises the southernmost waters of the World Ocean, generally taken to be south of 60° S latitude and encircling Antarctica. By way of his voyages in the 1770s, James Cook proved that waters encompassed the southern latitudes of the globe.

Are there 4 or 5 oceans?

Historically, there are four named oceans: the Atlantic, Pacific, Indian, and Arctic. However, most countries – including the United States – now recognize the Southern (Antarctic) as the fifth ocean. The Pacific, Atlantic, and Indian are the most commonly known.

Why is the Antarctic Ocean now called the Southern Ocean?

All responding members, except Argentina, agreed that the ocean surrounding Antarctica should be created and given a single name. Eighteen of the 28 responding countries preferred calling the ocean the Southern Ocean over the alternative name Antarctic Ocean, so the former is the name that was selected.

Why was the Southern Ocean created?

The Southern Ocean, geologically the youngest of the oceans, was formed when Antarctica and South America moved apart, opening the Drake Passage, roughly 30 million years ago. The separation of the continents allowed the formation of the Antarctic Circumpolar Current.

What ocean was named in the year 2000?

The Southern Ocean is the ‘newest’ named ocean. It is recognized by the U.S. Board on Geographic Names as the body of water extending from the coast of Antarctica to the line of latitude at 60 degrees South. The boundaries of this ocean were proposed to the International Hydrographic Organization in 2000.

What are 7 oceans of the world?

The Seven Seas include the Arctic, North Atlantic, South Atlantic, North Pacific, South Pacific, Indian, and Southern oceans. The exact origin of the phrase ‘Seven Seas’ is uncertain, although there are references in ancient literature that date back thousands of years.

Is Southern Ocean and Antarctic Ocean the same?

Southern Ocean, also called Antarctic Ocean, body of salt water covering approximately one-sixteenth of Earth’s total ocean area. The Southern Ocean is made up of the portions of the world ocean south of the Pacific, Atlantic, and Indian oceans and their tributary seas surrounding Antarctica below 60° S.

Does the new Southern Ocean completely surround Antarctica?

The new Southern Ocean completely surrounds Antarctica. The Southern Ocean extends from the coast of Antarctica north to 60 degrees south latitude. The Southern Ocean is now the fourth largest of the world’s five oceans(after the Pacific Ocean, the Atlantic Ocean, and the Indian Ocean, but larger than the Arctic Ocean).

What is the fifth and newest ocean in the world?

Updated April 09, 2018. In 2000, the International Hydrographic Organization created the fifth and newest world ocean – the Southern Ocean – from the southern portions of the Atlantic Ocean, Indian Ocean, and the Pacific Ocean.

How has the Southern Ocean changed over the years?

Over the past 30 years, the Southern Ocean has been subject to rapid climate change, which has led to changes in the marine ecosystem. By way of his voyages in the 1770s, James Cook proved that waters encompassed the southern latitudes of the globe.

Where was the first land discovered south of the Antarctic Convergence?

South of the Antarctic Convergence. The visit to South Georgia by Anthony de la Roché in 1675 was the first ever discovery of land south of the Antarctic Convergence i.e. in the Southern Ocean/Antarctic. Soon after the voyage cartographers started to depict ‘Roché Island’, honouring the discoverer.
