28:35 Hey Edgar, I know I'm months late, but my doctoral dissertation was, "Where ENSO and 'Chaos Theory' Intersect." An ENSO Cycle will happen in _any_ ocean basin with a band of open water between 5°N and 5°S of the Equator at least 4000km long, and deep enough so that the Thermocline doesn't hit ground. ENSO is an interaction between your oceanic currents and atmospheric currents. Specifically, ocean surface temperature gradients alter the atmospheric circulation, which in turn either reinforces or inhibits the ocean currents maintaining those surface temperature gradients. Given that, you're going to have 3 separate ENSO cycles in all but one of your Equator-straddling oceans. And 2 of the ENSO cycles are going to interact in a "chaotic" fashion. Specifically, the two on either side of that spit-o-continent coming up from the south, with open ocean north of it. In fact, you're going to have significant warm water spillover at that point, because the ENSO cycle raises sea surface height at the western end of the ocean, creating a "warm pool", while lowering sea surface at the other end. So that North-South protrusion of land is going to have a higher sea surface altitude on its eastern side than on its western side most of the time, leading to a lot of equatorial water continuing to flow westward around the northern coast of that continent. The exception: during El Niño phases, the warm pools slide eastward and the sea surface "flattens out." That's going to add some interesting climate features to this planet! Reply to this comment if you want me to think this through more for you!

The Peruvian Current flows in one cell from the Antarctic Current all the way to the equator, so I think that strange long current is acceptable. But for another case there is also a fairly similar situation with the Indian Arabian monsoon current, as well as in Southeast Asia, when seasonally reversing currents appear. But still, it seems to happen when there is landmass to the north.

[@xiphosura413]

Where you put the ENSO on your map is probably more akin to the IOD, the Indian Ocean Dipole. Something more like the ENSO would likely occur in the ocean to the west of it. In general, really good video! I hope people start to refer to this one more than your last for ocean currents.

[@Artifexian]

You're probably, right. It was a tight call

[@John_Weiss]

An ENSO will occur in any ocean with a few 1000km of open ocean in a band between 5°N and 5°S. Source: My PhD research. 😊 So pretty much every ocean on this planet will have an El Niño-La Niña cycle.

[@malusignatius]

Re: that weird little ocean. Given the shape of the continents involved, I think what you might have is a small summer gyre in the far north instead of one forming further south. As you said, it's hard to say for certain without some serious modelling software but that's where my intuition is pointing me.

[@kentario1610]

*Another* worldbuilding rec from Artifexian? With what a gem worldbuildingpasta has been I am excited!

[@GreyBearcub]

Hello, I have a question about what happened in minute 19:21, you mentioned in summer hemisphere it will be polarwards but in the text says more equatorwards... I got confused haha, could you please indulge a small explanation? Your videos and channel are awesome, and Madeline Hames Writes has an outstanding channel as well, she should have more subscribers, thank you for mentioning her in this video. Keep up the good content, both of you! Best regards!

[@SotraEngine4]

I'm probably a bit late to comment this, but I want to mention something In Norway, which crosses the 60 degree north thing, there is a place called Stad. It is a location along the west coast of Norway at about 62 degrees north. It's like a northern corner of the Norwegian west coast, separating northern and southern Norway If you listen to to Norwegian weater forecasts, you will hear "sør for Stad" or south of Stad often. This is because Stad is where the winds meet. North of Stad and south of Stad has quite different climates. You can feel it in the wind almost But Stad in a way is a corner. So I wonder if landmasses can push where climate zones changes, since 62 degrees is 2 degrees too much

[@FanFive5]

21:45 & 28:15 can't that be some sort of doldrum or a large bay lake? I mean, the sea ice blocks it off. and the sourthern most part is the most narrow. Not a lot of heat absorption...maybe?

[@Hasshe]

For that strange ocean, i almost feel like the bottom west-going line should not exist, and it would instead be a weird zone of no current. I'm not sure how possible that is, but having no current feels almost more realistic than having a tiny cell.

[@AlexChec]

There couldn't be a lack of current because of both the difference in latitudinal wind intensity and different water densities (ie, the seasonal ice melt from the north being fresher and the outflow from the bay pushed by the trade winds being more saline/mineral rich). And even though that trailing continental shelf blocks the main current from interacting with the sea, there would still be interaction with the surface water at the strait (although there might not be much *exchange* or transportation of water across the strait). It's possible that the southern sea could end up with really weak current or a seasonally-driven current like the South China Sea, but there couldn't be a total absence.

[@anarchosnowflakist786]

@@AlexChec could it be that all along the current going downward there's a smaller current going eastward which slows it down to practically a standstill at the bottom where it picks back up when it goes up in the eastern part ?

[@AlexChec]

@@anarchosnowflakist786 Possibly. Whatever the mechanics at work, I wouldn't expect the current at the lower latitude to be very strong. It might even devolve into eddies for much of winter until there's meaningful ice-melt and inland precipitation to restart large-scale water transfers. My only point was that it's too large a body of water to just sit still.

[@SAOS451316]

In Blender you'll get a white haze with that node setup when trying to hide individual texture layers. This is fixable by changing the color blend mode in the mix nodes to Overlay, and Linear Light in the case of the sea ice layers if you want them opaque.

[@Artifexian]

Did not know that! Cheers

[@mid8150]

I simply cannot comprehend how you are able to doo all this without succumbing to Executive Dysfunction. I've been trying and failing to do anything meaningful in terms of world building for the past 4 years, the closest I've got is a mental map of what I want to achieve. I would love to be capable of achieving my worldbuilding goals, but for some reason I just can't. It's like your immune to the negative side effects of Tolken Syndrome, how do you do it?

[@armata_strigoi_0]

TBH I think the key is a certain level of outcome independence. The most free-flowing and energising projects for me (and not necessarily worldbuilding, anything creative in general) are those where I simply do it step by step from the ground up and see where it takes me. You let the world build itself, so to speak. The projects I always get stuck in a rut with are those where I have very specific goals. I'm actually in a pretty similar position to yourself ATM - I have a major worldbuilding project on the go, but it feels like I'm constantly spinning my wheels because I have a multitude of predetermined factors (it's a TTRPG setting) planned out, but I want them to make sense and be consistent, so I'm simultaneously trying to build the world itself from the ground up and essentially "meet in the middle". Too many moving parts. But as I alluded to earlier, something I've learnt over the years is that when I relinquish my need for control (and frankly, my perfectionist tendencies) and simply allow the process to take the brunt of the effort, I'm exponentially more productive. The results are usually pleasantly surprising, too. As reluctant as I am, I think that's what I'll have to do once again. Maybe this isn't the source of your problem, but if it sounds familiar then hopefully my comment helps somewhat.

22:33 Not a professional but been monkeying around with Exoplasim simulator for a year with a high obliquity planet with Pole to Pole strips of land and ocean, and that really gets weird. Doldrums and atmospheric cells get really weird, like braided instead of making belts. Even with physics philters that get completely rid of Gibbs Ripples it contiunues to get all eddied up. I guess it is related to not having much East-West space for the Coriolis effect to develop fully and gets mixed up in the coasts, having this weird braided pattern. I would love to have feedback from an expert. Also I think it is great that you gave a shoutout to Madeline James Writes and Worldbuilding Pasta. Top tier content.

[@robertfaucher3750]

17:35 On Earth, New England is actually as cold as it is because the Gulf of Maine and Cape Cod captures the Labrador Current, and it Pushes the Gulf Stream towards Europe. I think though that this is the only example of this happening on earth. This gives New England a more Northern Europe type climate despite being on the same latitude as Corsica, Rome, and Southern France. 22:30 Here I would say the Eastern Bay there would act as a warming effect on the water, Kinda like the Carribean sea allowing a warm current to flow out of there.

[@yuvalorp]

[@justsaying4303]

they're different Niño/ Nina events that can occur in ocean. the classic ENSO in the pacific, Atlantic oscillations, Indian ocean dipole, Niño events in the Atlantic, etc

[@Dragrath1]

It might be worth noting that between a bay and a wide ocean you get what in oceanography are termed Mediterranean seas named after their namesake example which are bodies of water with a well defined internal circulation and generally one well defined primary inflow and outflow respectively. The big examples I'm aware of on Earth are of course for the Atlantic the namesake Eurafrican Mediterranean sea, The American Mediterranean sea a.k.a. the Caribbean sea + Gulf of Mexico(they have a single shared primarily water inflow outflow), the Arctic Mediterranean sea which is the Arctic Ocean(despite being generally considered an ocean the current flow is that of a large sea), the Baltic Sea and Baffin bay. The Mediterranean itself also serves as the source "ocean" for a number of sub Mediterranean seas which I'm going to admit for brevity. There are also some in the Indian Ocean Australasian Mediterranean Sea(basically the water flow through Indonesia) the Red Sea and the Persian Gulf. The Pacific despite being huge has such strong currents that it makes Mediterranean seas difficult to form In the case of that gyre at 22:00ish is there not a shallow water connection at that shelf region? If so you can expect thermodynamics to favor warm water transport into that otherwise enclosed sea because the energy transport is from hot to cold. Its going to be a mess but I would be surprised if there wasn't surprisingly vigorous fast moving currents compared to what would otherwise be expected to flow north south in that region driven by the temperature differential. Unfortunately specifics there are going to require simulation because it is quite unearth like however once you get an intuition for what the simulations reveal that knowledge can likely be applied to the more accessible albeit less accurate intuition based worldbuilding. As for the closest real world analog is the Bering Strait which has a net flow into the Arctic which is what leads me to suspect a dominant northerly flow would arise in your region. Also for completeness sake while its not a great fit the current driven geographical barrier in the Indo-Pacific dividing the Australasian Mediterranean Sea from the Pacific may have some relevance. As for Sea Ice complicated doesn't go nearly far enough to describe it since ice cover is largely also a function of the land and where ice sheets form can serve to seed and anchor ice shelves which in turn stabilize glaciers in a complicated feedback. Then once you get ice cover that changes the flow circulation and weather systems which shift where the ice forms. A net result is that over the Glaciation of the Northern hemisphere from the late Pliocene to the last Glacial Maxima the cordilleran ice sheet has grown more diminutive over time compared to the Laurentide ice sheet in the Northern hemisphere. Also its important to note that sea ice is much much easier to form in the Arctic since the Arctic is for all intents and purposes an enclosed oceanographic Mediterranean sea with a large area of coastline within the Arctic circle. Your polar sea region on the other hand is not as the encirclement doesn't include land which means there really isn't anywhere for sea ice formation to nucleate so instead of having Arctic like conditions you will have a situation more analogous to what occurred during the Jurassic cool period where your Northern hemisphere will likely only be able to support thin seasonal ice in the winter otherwise staying ice free year round in the Northern Hemisphere. The Southern Hemisphere will be a different story as the large continental area within the polar circle will give you a situation more akin to the late Paleozoic ice age where a significant portion of Gondwana was within the Antarctic circle and thus seeding the formation of vast continental ice sheets. If you want to change the situation in your Northern hemisphere you will need some land area within that polar region as otherwise the onset of ice age conditions will fail, it doesn't need to be much land just a little will do say from the effects of an archipelago or hot spot chain since as long as no warm currents interfere the ice area can cumulatively build up over hundreds of thousands to millions of years. There is a reason normal Ice ages have only ever occurred when there is a continent within the polar regions, the threshold needed to make ice form otherwise is not really reachable unless you have Cryogenian style glaciation where the whole planet freezes over. In summary because there is no place for ice formation to nucleate in your Northern Hemisphere there will be no ice there except seasonal ice. As a result you probably will have to cut that whole section as it is probably unphysical.

[@Artifexian]

Wow! Great comment. Lots to chew on. Thanks a mill

[@dayalasingh5853]

This series is so cool

[@dinubreu7477]

19:20 why should the current flow more equatorward on the summer hemisphere? Wouldn't it be shifted more poleward? (Similar to the ITCZ, which gets shifted northward during north summer, and southward during south summer)

[@Taqterra]

This was a really engaging episode. Looking forward to next time

[@hungvu262]

25:47 looks more like the alaska-oyashio current in the north pacific. The antarctic circumpolar is more a continuous westerly.

[@ajdogz5088]

Something interesting ive noticed is that in southern hemisphere summer, the itcz actually dips into the northern hemisphere near the west coast of South America and Africa, with the latter even continuing north for a bit in the continental interior before returning to the south. Goes to show that the ITCZ isnt exclusive to just one hemisphere per summer if conditions are right Edit: i mainly wanted to mention this cause it has the possibility of occurring in my world due to how the continents are shaped/positioned.

[@wellsmartineau185]

The skinny ocean would likely split into three zones especially during high energy seasons

[@bunbasss7772]

Thank you for very interesting content! Worldbuilding is great👍

[@yuvalorp]

In the place of the dwarf ocean currents I think that you should expend the ice mach more because even the "hot" current start very far north and it doesn't really cat heat from the lower altitudes so the ice can get even to the 60s'

[@Dragrath1]

One important consideration for the formation of sea ice is that it needs adjacent land area to nucleate without land area to nucleate you can't readily form stable thick ice cover so you will get a situation more analogous to the Jurassic cool period where the planet cools to the point where sea ice can form but because there is no land area in the polar circles the cooling fizzles out and hothouse conditions return. Thus in summary his Northern hemisphere geography configuration prohibits the formation of ice cover unless global temperatures drop far enough to allow glaciation at mid latitudes initiating Jormungandr(Gaskiers glaciation) of Cryogenian style glaciation. His land dominated southern Hemisphere set up will allow a southern hemisphere focused ice age conditions with the main consequence to the northern hemisphere being increased aridity much like was seen with the late Paleozoic ice age that spanned from the late Devonian through most of the Permian when much of Gondwana resided within the Antarctic circle so he doesn't need to worry about hothouse conditions resuming as happened during the Jurassic cool period but it will be difficult to get any real ice cover in his northern hemisphere without substantial cooling. Now if ice nucleation could initiate in the Northern hemisphere and spread far enough south to initiate that kind of runaway feedback sure you could get substantial ice cover but the same conditions largely preclude habitability since sea ice extending to within 30 degrees latitude is thought to initiate a runaway glaciation process based on modeling.

[@yuvalorp]

There is no problem of nucleation in this place because it have land in both sides of relatively small ocean,how I imagine it this part of the world should be stack in some kind of ice age because it doesn't get heat

[@Dragrath1]

@@yuvalorp The land area is outside the latitude zone of summer ice conditions which is what I had been referring to. Unanchored ice is likely to drift into the warmer currents and melt thus becoming seasonal

It’s really cool to see the more accurate ocean depths mapped to the age of the crust, however I can’t help but feel the artistic side suffered a bit because of this in the east-most and west-most oceans. The separation *looks* to me more artificial, where as before I really enjoyed the level of detail you had going on there with the sort of fractal borders, I wonder if you could do a compromise between the two? Looking at Earth’s ocean maps you don’t really see that clean segmented separation anyway, so I think you have the leeway to reintegrate more of that interesting detail you had going on before.

[@Ninjaananas]

[@theofficiallobst6592]

I was wondering how much upwelling and downwelling would affect climate in this context? I remember watching this oceanography lecture a while ago, and I took a lot of consideration of that kind of thing when making my own maps, but wasn't really mentioned here - was that just more for simplicity's sake, or something else? Love this series!! And here's the lecture, by the way: kzbin.info/www/bejne/enrYl5uYjsdgeqM

[@Artifexian]

Downwelling won't the discussed. Upwelling will be discussed in a future video.

[@Kalithrasis]

Too fiddly for this video, but you can get small counter currents that run up along the coasts opposite the main ocean gyre currents. California for instance has one called the Davidson Current which hugs the coastline and most of the year sits about 200 meters below sea level. This current draws warm water from Baja California north whereas the big California current draws water south. In winter, it surfaces when the northerly winds slacken and helps moderate the winter ocean temperatures along California. The slackening winds also reduce subsurface upwelling which is also part of what makes California's coastal waters so chilly.

[@anubia-bastet8825]

I am curious about worlds with one super continent. Would it be the same process just with much bigger gyres?

Could the bottom of that weird ocean possibly be treated like a bay or a sea, or is it maybe too large for that? I feel like the long, skinny landmass underneath it makes the weird bit of that ocean look more like a large sea to me🤔

[@Dragrath1]

Yes it would be classified as a sea as a sea can exist within the context of a larger body of water such as how the stability of the North Atlantic gyre creates the Sargasso sea, the only sea on earth completely enclosed by an ocean since a sea only requires a current separation from the main global circulation

[@SotraEngine4]

Would ocean plates colliding, resulting in island arc formation, redirect the ocean currents?

[@John-Smith93]

Amazing crash course, thanks! One question though: Why do the Gulf Stream and North Pacific Current split when reaching the west of Europe/the US, with one part moving north to Scandinavia/Alaska, the other south to Africa/Mesoamerica, while the 3 southern gyres don't do that? They just close the circle without a major poleward current branching off. Is like the Antarctic Circumpolar Current getting in the way in the south but something similar can't be established in the north because land masses like Kannada/Siberia are in the way, or like what's going on?

[@Artifexian]

Yup! Your analysis is spot on

[@Lilas.Duveteux]

That encased in mountain continent seems promising. Because, it'll have like a tiny band of humid subtropical at the south of the more desert one, with meditterenean and continental up north of the coast, with some cold step and Ds climate types all over most of it, if I get it correctly, while the Western half that is very long North to South would probably have every single climate type possible in a single continent, from tropical rain forest to barren tundra. Same for the South Pole continent. The mountains would create a lot of micro-climates, which would suggest a rich mosaïque of cultures. Mega australia would probably have a lot of continental climates as well with all those off-shore winds. The islands would be quite rainy although, with the two most suitable climates for agriculture: humid subtropical and meditterenean. Both inland bays would be great sources of fish and kelp. Perhaps such cultures would develop alguiculture early on in their history compaired to those on earth as a way to cope with an otherwise dry land. In terms of biology, it would probably have a lot of "return to the water" evolutions.

As for that seasonal gyre.... It is your own bloody fault that it is so weird -- *you* built this world ! :P But what an opportunity for very interesting culture building. I cannot wait to see what happens next.

good morning artifexian

[@altair4828]

this is honestly my second favourite part

[@DominoPivot]

I'm still not super into these nerdy topics, but I'll say, these climate maps always look super cool, and the societal impacts of currents and ENSO events will be interesting to consider.

One question: Is it plausible for a traditional planetary system to have more than one habitable planet? And how many planets can fit inside a star's habitable zone.

[@Artifexian]

In theory, yes. An article got published in 2020 called "Dynamical Packing in the Habitable Zone: The Case of Beta Can" which IIRC says that for a sun like star the max would be six.

[@PizzaChess69]

@@Artifexian If we assume a ratio between adjacent orbits of 1.3 to 1.4 (which is what I use for the inner parts of my systems), the maximum number of stable orbits in the habitable zone is 2 or 3, depending on how conservative or optimistic we make the habitable zone (remember, the SS itself used to have three habitable planets). Also, when calculating the HZ, I take L^0.5 and multiply that by 0.8 for the inner and 1.5 for the outer edge (I am defining the HZ of the Sun as 0.8 - 1.5 AU). Is this a good method of calculating the HZ, and are the values 0.8 and 1.5 realistic, or too optimistic?

A small note for sea ice that the references you used are all based on 1979-2002/03, definitely post-industrial. Global warming/cooling cycles and anthropogenic climate change heavily affect the extent of sea ice, so perhaps a pre-industrial world would have cause for further extent of sea ice.

[@Artifexian]

Head over to WorldbuildingPasta for that. Honestly there's not much to see really. You prep a bunch of stuff, set up the app, input some parameters and then after a while out pops a map.

of course, love the long-await'd content; but, the Audio of the 2k version sem'z goofy... I had to watch it in 1k; still worth the wait, Not what'z gon'ng on there, I believe I noticed that in the last video too

That's not something I'm experiencing on my end. And also not something I can control. I upload a 4k video to KZbin and they make all the different versions

If you're clumsy like me and you keep activating the wrong layers in Blender, it's way easier to keep two files open, one for winter and one for summer. Much less margin of error.

Hey artifexian, I'm making a little program to help me with my world building process, do you miwordsmith? Some of the math from the worldsmith?

how come the south sea ice goes more equatorward (35ish degrees south) in the southern hemisphere summer but not in the southern hemisphere winter (70ish degrees south)

Whoops! My bad. That will need to be fixed. Thanks for pointing this out

I know you use the word 'morphology' in your language videos, but I don't feel like your use of the word in this video matches what you want to express. Morphology should be reserved to describe the study of parts describing a whole or the fields of study in Biology and Linguistics. Just say 'shape' instead. Also, I believe you shouldn't keep yourself from improving your landmasses if the ocean currents don't line up with them properly. Think about how oceanic flow helps shape continents. You've got a couple canals and bays that look counter-intuitive (they would have been reshaped by the currents during their evolution, not _after_). Also, I do believe the currents should follow the heightmap of the oceans a bit better, especially in the shallower parts.

I'm not a fan of the background music. The bass sounds like popping. Combined with the voice over makes it unpleasant.
