Ocean Depth Calculator - Worldbuilder’s Log 27

[@worldforger0]

I love how we went from: "Should we even do an episode on oceans?" to "Yeah, so we made not one but two episodes on the oceans."

[@jasonyesmarc309]

I'm so relieved. I often try to incorporate underwater settlements and economies but there are so few resources for that kind of worldbuilding, and getting into oceanography enough to know the search terms has not been progressing well for me.

[@LoganKearsley]

The span between new ridge height and old crust depth should probably scale inversely with gravity.

[@dylaneverett4586]

U genuinely don’t understand the excitement I feel whenever I see a new artifexia episode in my subscriptions feed

[@mllhild]

So now the deepsea monsters can be a lot closer to the shore

[@htth3152]

One thing I noticed overlaying Earth map over Cretak's is that Ezri and Jannar reach north Canadian latitudes, which means, if the planet experienced ice age equivalents, the north coasts of these condinents would've seen extensive, probably Laurentide sheet-level glaciation and would be more depressed. I can totally see that circular lowland in the middle of Jannar's northern half being flooded and forming a nice Hudzon bay analog.

[@Dragrath1]

Adding to this looking at a seafloor sediment map its worth nothing that the areas where ice anchored to the seafloor during previous glacial maxima its worth noting that there is very little if any sediment remaining on those parts of the continental shelves. The areas where former icesheets were present on the other hand have thick sediment load as that is where the glaciers largely dumped their loads

[@GmodPlusWoW]

With ocean depth out of the way, I wonder how many episodes it'll be before we climate-map this sucker? 'cause with all the interplay between latitudes, ocean currents, mountain ranges and landmass sizes, there's gonna be a lot to take into account.

[@vde1846]

Can't wait :)

[@roseflood1612]

I believe he said the next proper episode would be tides, and he'd move onto climates after that. So maybe only two episodes to go?

[@GmodPlusWoW]

@@roseflood1612 Probably. While tides do help form the outline of continents, rivers and rainfall have a similar effect, since they gradually erode mountains, and their flow brings minerals and sediment to the shoreline.

[@travisgravelle7687]

Oceans and their currents are huge driver of weather patterns. If you know your Oceans you can figure the climate and weather for a given location.

[@ColinPaddock]

Although… figuring out how ocean currents respond to bathymetry is hairy. An ocean bottom doesn’t help much with plausibility. In most cases, just sketching out circles on the map is about the best you’re gonna do without a full atmospheric/hydrospheric GCM…

[@travisgravelle7687]

@@ColinPaddock general rule of thumb. Deep water is gonna be cold unless heated by thermal vents. Surface currents are gonna be dictated by planet rotation prevailing winds and land masses. Equator hot, poles cold. Flowing in circles.

[@Dragrath1]

@@ColinPaddock Not necessarily while much of the ocean remains unmapped at the kinds of resolutions needed to identify major geological features(i.e. the seafloor data we see is usually and average over a broader geographical region thus hiding local variability due to say typical volcanic seamounts and or craters etc. But based on the recent high resolution survey which brought our coverage of the global ocean to around 20% mapped (80% still not mapped to that level of resolution) the hypothesis that seamounts are responsible for determining the locations where deep oceanic upwelling occurs.

[@OnLowBattery]

I'm glad the blender thing is working out. Can't wait to see what you do with the new skills you have 😊

[@CuriosityCore101]

THANK YOU SO MUCH Ocean depth in my world is going to have a huge impact on things like where the "sea monsters" live and shipping routes and things.

[@eostyrwinn5018]

Ha. The comment I didn't leave (but almost did) on the last video was going to be something about how given, your history, you claiming something is too number-crunchy to be worth it just means there will be a video on it in a couple years. I guess the timeline got sped up for this one

[@Auroral_Anomaly]

Thank you, this series inspired me to make my own world! I’ve been working on it for a while! You are a great KZbinr!

[@altejoh]

Nice! I wonder if there is adjustments that can be made for say, higher or lower gravity worlds, or for worlds with more or less oceans. Like desert or water worlds. Edit: Looking into it, it looks like you should be able to make adjustments to these equations by adjusting the assumed densities of water and rock, which are probably difficult to mathematically scale to gravity/ocean depth but maybe there will be a simple chart answer in literature somewhere, perhaps in Seager et al. 2007, Mass-Radius Relationships for Solid Exoplanets, as you have referenced in older videos?

[@mllhild]

The 2600 figure probably comes from the fact that anymore and it pushes down the crust, constricting the flow and hence slowing down growth. This doesnt really change with gravity since what matters is the relative density of crust vs water. On an world with more water you would have a deeper base, yet since density remains the same this means you likely would end up with high point of around half the depth (2600/5000). The funny idea is if you make the rock lighter, would it be possible to have those ridges to be always above the the water? This would cut your world into a lot of separate oceans separated by mountains, somewhat like One Piece.

[@de_steen_505]

YESSS ANOTHER EPISODE 😍😍😍

[@Deipnosophist_the_Gastronomer]

This is coming together really well. 👍

[@Stephen-Fox]

Very cool. I can't say I have any projects where this feels like it would be useful for, but the maths is really neat so if I ever do wind up with a project I now know exactly where to look.

[@daniel_rossy_explica]

I'm so far behind in my project that I think I can say it is officially abandoned. I didn't even get to the "plates colliding" part.

[@yellowbutterfly6796]

the thing about abandoned things is they are ripe for exploring and reclaiming :D. if you want to, of course

[@daniel_rossy_explica]

@@yellowbutterfly6796 unfortunately, life & work gets in the way of worldbuilding. I can't drop everything and devote all my time to worldbuilding as Edgard did.

[@bourbonbobo]

Just think of the day you realise you have time. In the back of your mind start thinking about the things you will be able to do when you do. Let yourself daydream just a little and you'll have lots to work with when you do find the time.

[@ColinPaddock]

@@daniel_rossy_explicaAt least this way, if you retire you won’t have to take up golf.

[@RedBlaze45]

You're welcome, lad! Cheers!

[@SlushieeeeTheCatgirl]

I'm too dumb to know any of what these strange alien graphs mean. Very cool.

[@RandomescStuff]

Nice! I love this stuff!

[@Writer-Two]

Woo lets go

[@rhaikh]

I assume the uniform ridge depth is a function of oceanic volume

[@itisALWAYSR.A.]

There must be some reason it plateaus at -6400m. Ocean pressure? Planet mass? Outward force from the core? A function of Earth's size vis some component of the square-cube law? Legit wouldn't know where to begin, but saying Earth is this suggests other planets would not be so.

[@OddcessiveNooBurrito]

Is there a way to use the speed of the tectonic activity at ridges and subduction zones to calculate a max height or depth for MORs or Trenches?

[@alapikomamalolonui6424]

Gorgeous...!!!! 😊🤙🏄☘

[@elysainempire4628]

Yeah Edgar, I seem to be have a problem getting my cratons to follow the parent plate, even with the plate anchor feature. With the anchor feature all but the parent plates cratons return to their starting location and remains disconnected. Is there any solution to this, aside from manually moving the cratons?

[@eshaanbhargavpatel1768]

Can you make a video for planets without tectonic plates5

[@ATOM-vv3xu]

Damn late on an artifexia episode cuz I was on vacation

[@tnt-boom]

Can you make another wlrs...t?

[@ananas_anna]

Hey Edgar, is WLRS…T going to return at some point?

[@az397]

And what about the inverse, what about mountain height? 😅 Sorry, I don't want to bother but it hitches my brain.

[@flourishd1]

I am an upcoming writer and i hope to someday work with you and create a massive fictional spinoff series solely based on your world.

hi

the videos are great but the music is so repetitive and grating, i have to watch with sound off and with auto-generated subtitles on to be able to actually enjoy these
