Actually no. Nemo's dad just swim around the Pacific tropical area (maybe water around Eastern part of Indonesia or water around Papua New Guinea) and then go to Southern Australia. Sydney.
And yes, in that Eastern part of Indonesia's water and also the Philippines water there are some military naval equipment things. Like the military ship wreck and the sea mine.
Eastern part of Indonesia > some random trench(maybe Mariana Trench?) > Sydney. That's the route maybe.

As far as I am concerned, there is at least 7 ways how to divide oceans and possibly many more, and some scientists do recognise the Southern / Antarctic Ocean. And the same thing pretty much hoes for continents, the very number of continents differ by who you ask and especially Europe and Asia have rather arbitrary border:)

2:54 Awwww...I can't get mad when a pun is read that cute. 😁
Why would anyone ever get mad at a pun anyways? Maybe apart from situations where joking in general is considered inapproriate, like at funerals.
Heck, I literally listen to a podcast called Pun Watch, and I love it.
The problem is when you don't get the pun. Like me...
@@FunnyMemes-dr3se Believe me I've felt that pain brother. Especially when you're in a group and everybody's laughing but you at the joke, so you just nervously chuckle hoping none notice your awkwardness.

@@joelproko nah I would never be truly mad. I might GROAN loudly, but never true anger.
Dividing oceans is about identifying geographical regions - places on the globe relative to each other. Exactly the same as land.
But they are talking from an oceanic diversity and similarity point of view. For land, its easy to understand what lives where since most land borders are close enough together to make a fine enough boundary for identifying unique animals or geography. But with the ocean, since we mostly travel over it, or on its surface, identifying what lives below it at a glance is much harder with the current, very broad geographic regions in place. And trying to divide them by other factors, such as underwater geography, currents, temperature, or salinity is just as hard.
@@pauldeddens5349 true - but at least this video totally omits the really sticky issues (and I'm glad it did, because that one issue is honestly just a show of human's worst).
@hawkturkey Well this video isn't an argument to redefine basic geographic maps of the oceans as we use them, its to help educate people how vague our geographic borders for them are, and the other ways it could be organized, not that we should adopt or change the system
@jocaguz18 kinda... it's ironic I know. But I often hope that humans realize how puny and powerless we actually are and appreciate the larger forces for a bit.
@@mukrifachri So true, mankind think that they are a big deal on this universe n the reality is death n khalaasss, I don't know if anyone agree with me or not but I felt it!!!!!

Every time I watch a MinuteEarth video I grow more convinced that they make them solely for the pun at the end.
It depends what you're splitting stuff up based on. If it's for a nation's political influence, of course they're going to be based on nation boundaries. If it's for tectonic activity, you'll split them up according to the plates. If it's for marine biology, it'll be split based on biodiversity variables.
The maps you often see are just using the per nation PoV, since most people see the world as a bunch of nations rather than what tectonic plate or wildlife is present.
Proving yet again that Australia & Antarctica are both islands.

"While these boundaries may be clear and convenient, they don't really say much of anything about the oceans themselves... which seems kinda important." Don't worry, it isn't. Categorization and nomenclature is inherently subjective and relative to perception. The length of the second doesn't tell us anything about the nature of time. The unit of the meter doesn't tell us anything about the nature of distance or space. The only important aspects of a particular ocean division scheme is that it is 1. consistent, and 2. agreed upon. A lot of categorizations aren't even clear or convenient, so the fact that ocean divisions already have that going for them makes the existing divisions worth keeping around.

ARE YOU A JOJO REFERENCE
@@goodguycarl YOUR NEXT LINE IS: "YES, I AM!"
The arbitrary lines on the map for ocean divisions are mostly navigational in nature. While "Panthalasia" isn't exactly in common use, "the ocean" is with the same intended meaning of a single body of water. All the other divisions like the Southern Ocean, the North Atlantic Current, the Sargasso Sea, etc. are purpose built for what they need to describe and don't care if they overlap some boundary meant for something else.
The Atlantic, Pacific and others like them originated with cartographers trying to designate where things were based on where people were going, and they still kind of function that way. Those "pointiest bit" lines are navigation choke points and that's really the point of these divisions. The difficulty in getting from one ocean to another via a boat on the surface. And for that reason, they really shouldn't change. The Southern Ocean is important for scientific research, but for navigation it has no choke point. The north/south split of the Atlantic didn't even go away, it just has limited use for vessels where it matters.
And we saw how important these distinctions are for navigation when the Suez Canal was blocked. If I turn a ship too sharp and it runs aground in between the north and south Atlantic, you probably won't even notice because you barely have to adjust course to get around it on the very unlikely case you were on the exact same course. But to get from one navigational ocean to the next requires going through one of the few spaces marked off by "pointy bits" or a canal.
The problem is using the wrong tool for the wrong job. If you are using a hammer to put in a screw, it's not that the hammer is a bad tool and we should stop making hammers. You just chose the wrong tool. And that's what's happening here. These tools do their job just fine. Getting screws into wood seems kind of important, just as the various scientific aspects of the ocean seem kind of important (1:53), but the hammer and these navigational oceans are perfectly valid tools when you use them for the right things.
1:56 "ah, I see you are man of culture "
1:57 Just remember he became a marine biologist by writing a thesis on a starfish he saw the other day
best video i "ever" watched from MinuteEarth
Actually, the world technically has three oceans (where "ocean" is defined as a single contiguous expanse of oceanic crust); the World Ocean, the Black Sea, and the Caspian Sea. The Black Sea is separate because, while the Strait of Gibraltar is oceanic crust and so connects the Mediterranean to the World Ocean, the Bosphorus is actually over continental crust, and so separates the Black Sea from the World Ocean.
Sci show tangents also released their podcast on oceans today.

Its amazing to think that the Oceans are the hugest biome in the entire planet
Never in my life had i thought that i will see a jojo reference in a minute earth video
Thanks for answering my life long question
I was anticipating the pun and I still liked it!
I think that they should be divided according to our needs like the case with the southern and northern Atlantic (I mean these hydrographirs could always come handy in my suggestion) , but make other versions of ocean mapsdepending on that factors like saltiness geology you name it .
"Cut and Dried"? Really?
Also, aren't the ocean (and sea and lake and ...) names for human beings to understand where they are? Why would things like salinity matter?
Salinity, water currents and temperature influence what life forms inhabit a certain part of the ocean and its shape and geology. It would be more useful to divide the oceans according to characteristics they share because it makes studying and comprehending them easier.
Because salinity is factor that can be used to differentiate the world ocean cause it's all connected unlikes lakes and rivers (you could argue rivers are still connected to the ocean but it's going uphill and inland and it's very distinct where rivers begin and end). Salinity changes the ecosystem that a certain areas in the world ocean will display, also I'm assuming there using multiple factors not just salinity to divide the oceans
How saline the water is would have lots of effects on the environment within the waters. It would effect the plants and animals that live there and the propensity of the water to freeze or change temperature. When trying to look for unifying characteristics it seems reasonable.
I appreciate the replies. I get why "salinity matters" for things like what lives in each patch of water, its freezing temp, etc.
But I stand by the assertion names are for human readability. If the salinity, currents, life, etc. off the coast of, say, Senegal was vastly different than off the coast of Mauritania, calling them different names might make sense to marine biologists, but it would confuse the hell out of "normal people".
Agreed - location is one reason to divide and separate the oceans. But as we learn more about all Earth's water, it's becoming clear that geographical location is only one of many ways we *could* divide the oceans - and it seems that it doesn't do a very good job of describing any actual characteristics of the ocean water itself. So it depends a bit on why you want to divide up the oceans in the first place...that's why this is such a difficult question to which there's probably no perfect answer! -Kate
Thanks for the information
It’s kinda ironic that the one ocean that is unofficial is the ocean most clearly defined from the rest of the oceans and most recognised my the scientific community

In my country Spain, in the school we count the antartic ocean as a separated one
Why? That definition is pretty recent, Australia says it borders that ocean and basically the definition of it has been all over the place which is why it isn't really taught to most people unless one is part of a specialty field.

@1:55 Starfish crusader
My idea on how to divide the oceans:
Everything about 50 degrees north is the Arctic ocean, and likewise everything below 50 degrees south is the Antarctic ocean.
From there we have the rest of the oceans; like the Pacific is located around the Pacific plate... etc.
1:56 made my day
There is actually another natural divide between two seas; tbf they are not oceans, but I think it deserves a mention. The Baltic sea and the North sea have different densities and salt levels too. They meet at the tip of Denmark, so coincidentally at the same point where IHO would draw the border.
*sees video title*
Me as an intellectual: Because of All Blue being connected to the treasure One Piece
Except Antarctica. All chill, less salt.
Independent oceans for each current like a continent, with oceanic "countries" or subcontinents divided by ecosystems (to clearly define temperature, weather, wildlife) across the water and thru the water column. Sounds a bit fantastical like an elvin tree city... layers as different sub continents, with side boarders were the ecosystems change or currents occur. Why not?
