National Geographic Recognizes New 5th Ocean (nationalgeographic.com) 64

On World Oceans Day, Nat Geo cartographers say the swift current circling Antarctica keeps the waters there distinct and worthy of their own name: the Southern Ocean. National Geographic reports: Since National Geographic began making maps in 1915, it has recognized four oceans: the Atlantic, Pacific, Indian, and Arctic Oceans. Starting on June 8, World Oceans Day, it will recognize the Southern Ocean as the world's fifth ocean. "The Southern Ocean has long been recognized by scientists, but because there was never agreement internationally, we never officially recognized it," says National Geographic Society Geographer Alex Tait. Geographers debated whether the waters around Antarctica had enough unique characteristics to deserve their own name, or whether they were simply cold, southern extensions of the Pacific, Atlantic, and Indian Oceans.

While the other oceans are defined by the continents that fence them in, the Southern Ocean is defined by a current. Scientists estimate that the Antarctic Circumpolar Current (ACC) was established roughly 34 million years ago, when Antarctica separated from South America. That allowed for the unimpeded flow of water around the bottom of the Earth. The ACC flows from west to east around Antarctica, in a broad fluctuating band roughly centered around a latitude of 60 degrees south -- the line that is now defined as the northern boundary of the Southern Ocean. Inside the ACC, the waters are colder and slightly less salty than ocean waters to the north.

Extending from the surface to the ocean floor, the ACC transports more water than any other ocean current. It pulls in waters from the Atlantic, Pacific, and Indian Oceans, helping drive a global circulation system known as the conveyor belt, which transports heat around the planet. Cold, dense water that sinks to the ocean floor off Antarctica also helps store carbon in the deep ocean. In both those ways, the Southern Ocean has a crucial impact on Earth's climate. [...] For now, by fencing in the frigid southern waters, the ACC helps keep Antarctica cold and the Southern Ocean ecologically distinct. Thousands of species live there and nowhere else. By drawing attention to the Southern Ocean, the National Geographic Society hopes to promote its conservation.

    Not carving it up into more and more smaller pieces.

      I remember being in grade school wondering why Europe was considered a separate continent from Asia. There;s the Indian "subcontinent" as that's separated off by mountains. Sometimes I'll see China also described as a subcontinent. There's a subcontinent that is called Southeast Asia, Arabian Peninsula, or some variation on those. I can see Europe as an Asian subcontinent but that dividing line would be at the Ural Mountains, not some political border. Should Africa even be distinct from Asia?

      We divide things up all the time as a matter of convenience. We can't have a nation as large as the USA managed by one government. Even when the federal government could simply lump the whole nation under one jurisdiction for something it tends to break it up into zones for circuit courts, NRC regions, radio call sign groups, independent sub-national grids (including one now (in)famous state grid in Texas), and more divisions for different reasons.

      One unifying act was a bunch of separate nations coming together to form the United States of America. People forget that the USA is a federation of independent nations. People think the USA is a nation divided into administrative areas for the convenience of the national government to enforce rules they decide upon in DC. DC exists to enforce rules in distinct areas of law carved out for the benefit of these independent nations. The states unified on a defined federal border, then the federal government divided that responsibility off to DHS, and further divided that into enforcement by land, sea, and air. The TSA protects the border at airports. The USCG at seaports. On land that's Customs and Border Protection. There's more to DHS than that too. DHS has a training center, infrastructure protection (which seems to be dropping the ball plenty lately), cyber protection, Secret Service to protect high profile federal employees, etc. We could lump all federal law enforcement into one group but the FBI under Justice has a different enough job than TSA under DHS, which is distinct from State, Commerce, etc.

      If we are going to divide this out then why not "Antarctic Ocean"? It is defined by the flow of cold and low salt water around the continent. No doubt from the glacial melt as it flows off the land.

      If these division bother you then don't look at all the "seas" that the oceans are divided into. There are not "seven seas" as told in old folklore, more like dozens.

        Let me know why a bunch of map writers, should be prioritized over scientists on the world's stage. Is it somehow our fault that National Geographic wants to be purposely defiantly ignorant about a name that has been in use for literally hundreds of years?

        In other words, this is a pointless non-issue for paper pushers who pretend they still have a relevant job. And pretending there are borders in our oceans to justify more labels, is like pretending there are sides in a Swamp.

        • Let me know why a bunch of map writers, should be prioritized over scientists on the world's stage.

          Why is the agreement not scientific in the first place? I mean we didn't rely on map writers to demote Pluto into a Kuiper belt object, that as an agreement of scientists.

          I think the fundamental problem is we have the wrong people on the table doing the agreeing.

          • An agreement of four scientists who were the only ones left at the end of a long day of discussions, presentations and voting on stuff when the rest had gone off to join the after party. But that number was considered quorate, so now Pluto is a trans-Neptunian minor planet that was originally a Kuiper Belt object. Maybe.

            • Nope. A vote by four scientists. An agreement by an overwhelmingly large portion of scientists who adopted the nomenclature without complaint or protest.

              • There are a small number of scientists who get moderately het up about the question. A smaller number don't actually work on exploration of Pluto and other KBOs. Most see the swarm of "minor bodies" in the inner, middle and outer parts of the solar system, and recognise Pluto to be part of that group, not the small group of much larger bodies which can push the minor bodies around with no orbital consequences to themselves.

          You must be referring to marshes or wetlands - I had in mind the Pentagon. ;)

          • Marshes, bogs, fens and swamps are all types of wetlands.

            Essentially, a swamp has woody vegetation (trees, shrubs), while a marsh is mostly reeds and grasses.

        • Actually, within the sciences it's been described as "the Southern Ocean" since at least Cook's expedition, so that's about 250-260 years. And Cook was a pretty damned good mapmaker himself.

        Yeah, right. Sailors have been using a term for centuries but there was just complete confusion until there was "international agreement". Bullshit. International agreement is about ownership and territory, not some strange semantic scenario in your head.

        • Not sure I would use scuttlebutt as an example of a word used by sailors without international approval. Especially since it has two meanings.
      • Oceanographers consider Earth to have but one ocean.

        Those other places are seas; not oceans.

      I had never even HEARD of the "Southern Ocean" until about a year ago. Literally it had never been mentioned in any class I'd taken, any book I'd read, or any TV Show or Movie I had ever seen.

      • That's not a very meaningful statement without you indicating how many years you'd gone without hearing the term "Southern Ocean".

        There was a time when I heard the term for the first time. That was probably several years before I started to formally study geography and geology (as in, there were slots in my time table labelled "Geology, room this" and "Geography, room that". So, say, about 1975, maybe a year or two earlier. So, call it about 10 years of not hearing (or noticing) the term, and 45-odd years

      Logic and truth now run a distant second to inclusiveness and equity.

      It's a wonder they dictate definitions at all. Who are we to say one person's pond is not an ocean?

    • They were a well-respected organisation. Now their opinion carries as much weight as that of any other part of the Disney Corporation.

    So help me, if "science" decides tomorrow that there's an eighth continent, I swear I'm going to start burning some books!

      Nobody 'bought out a highly respected organization'. The National Geographic Society is a charitable organization made up of scientists and educators. The National Geographic CHANNEL is a joint operation between the NGS (27%) and Disney (73%). Disney runs the channel, with SOME of the content provided by NGS.

    • I care what they say because why?

      Because intelligent argument is based on the message rather than ad hominem attacks?

    • Rupert Murdoch now owns the National Geographic Magazine and TV show. I think there is still a non-profit arm that pays for explorations etc. (which provides the material for the magazine and TV show, presumably benefiting Murdoch). Even so, people who donated large sums of money and even their estates before the takeover are probably are probably not too happy (or are spinning in their graves).

      We need to distinguish between National Geographic Partners LLC with the National Geographic Society. The former is majority owned by Disney and is responsible for all commercial products. This includes TV, print, and events.

      The National Geographic Society is a separate non-profit entity, although what their actual purpose is now seems unclear. They may just be a shell organization who owns part of National Geographic Partners LLC.

  • That allowed for the unimpeded flow of water around the bottom of the Earth.

    Someone needs to be slapped for that.

  • If we have an arctic ocean, it clearly should be named the antarctic ocean. NatGeo is clearly racist against ants.
    • Theres no Arctic ocean, just an Arctic sea. Technically Antarctica is incorrect since there isnt an independent Arctic land mass but its way too late to rename that without a huge debate. My guess is Southern Ocean rolls off the tongue better.
