An ancient ocean in Ice Age Eurasia: Every 5 years

During the Ice Age, an ocean lasted during 50,000 years in Eurasia. One human could going down the Danube river from Germany, to reach Himalaya, or Arctic Ocean or Baikal lake using the greatest hydrological basin of all time.
When three inner seas were an unique paleo-ocean.

RIP Aral Sea, hopefully we shall sea you again

[brandoncampanaro]

Imagine living in that time when the Caspian was an ocean

So, you could sail from Turkmenistan to Spain?

Now in Kazakhstan the condition of the Aral Sea is significantly poor; the sea is drying at a low rate at this time. But it seems to me that this is drying every thousand

Respect! Must have taken a lot of effort to produce - thanks. Really interesting, and beautifully made.

It’s kind of interesting that the Romans technically could have seen a much smaller Caspian Sea

Sweet Jesus your content is pure gold. Youtube doesn't deserve you, this should be displayed in some fancy science centres instead!

its kinda insane how the caspian and aral seas keep fluctuating.

As I've understand:
6:55 Neocaspian transgression
6:37 Late Khvalynian transgression
6:11 Early Khvalynian transgression
5:00 Late Khazarian transgression
2:12 Early Khazarian transgression
Sorry if not correctly named, this is how transgressions are commonly referred to in Soviet paleogeography.
But i've noticed some different picture in textbooks. Late Hazarian was not as big as Early Hazarian, whereas Early Khvalynian was even bigger than Early Hazarian. It looks like the second and third transgressions in that video are switched. In other cases shorelines almost the same as drawed in textbooks. On other hand quick view to the papers reveals slightly different classifications and shorelines (maybe it is still a matter for debate?), though only abstracts are accesible to me.
Have a good day!

Interestingly, now the Aral Sea has dried up completely, well, almost, there are several lakes left. Irrational use of water from the Amudarya and Syrdarya.

A lovely illustration of the effects of ice ages roughly every 25, 000-40, 000 years. I was startled that the Caspian and Aral Seas disappeared regularly during the period of ice ages. Liked and subscribed!

[rbasket]

To all europeans and a lot of indians, afghans and iranians, this is were our ancerstors lived. Crazy to think, not that time ago, they lived in places that no lo ger exist as they were. Now a warren place, once a place birth of civilizations.

Central Asia is so interesting.

[NerdyLlama]

Does that mean that the Aral Sea is not damaged beyond the point of return, since it is typical for it to appear and disappear?

Hmm. I'm still in doubt. There are several issues
1. Several times seas connected through Kuma-Manych depression and Uzboy, but their levels not equal. It's contrintuitive and contradicts to the laws of physics. How sea levels can conserve despite connection and water flow from one sea to another?
2. Several times Aral and Caspian regressed and progressed almost synchronically was shown. But there is one river that flows either to Caspian or to Aral. Thus, I expected to see when Caspian level rises then Aral regression occurs and vice versa. But even closer to our age, when Volga river not starts from an ice sheet, both Aral and Caspian depicted progressed together.
3. More about historical times. There was plethora of states in that region. That time is well documented. While reading historical literature i don't remember that authors mention progressing of Caspian. Moreover, the was cities (and still is) on the shore of Caspian. One of them, Astrakhan, previously Haji-Tarkhan, previously Itil, Saqsin etc. localized on Volga river's delta and it inhabited since 8 century AD. So I feel a cognitive dissonance. How can economy and sea trade of entire states work when shore line changing all the time? Maybe your model miss something?

[GermanCountrybaII]

Its crazy how gigantic the Caspian and the Aral sea were, also crazy that the Black sea has almost the same shape right now as 100k years ago

[michaljanovsky]

amazing videos! love the informational value and music

[SulfateNa]

It kinda fascinates me, that couple MYA my homeland was completely submerged under the ocean, there was only small island(nowadays it is northern Nakhchivan and also part of Small caucasus mountains) and as the time passed it turned into entirety of Azerbaijan

Hey Kaldisti 👋, When Was The Caspian Sea At It's Height ? Which Year ?
