The Secret at the Bottom of the World's Deepest Lake

If you think there might be something spooky at the bottom of the world's deepest lake, you're right. Besides being the deepest lake on Earth, Lake Baikal supports a bizarre collection of species that are found nowhere else on earth!

Fun fact. The lake is over 1600 meters deep, but the rift valley in which it sits is about 7000 meters deeper. Most of it is filled by the massive amounts of sediments that have accumulated during those many millions of years.

There is a also a greatly endangered subspecies of fresh-water seals living in a single lake in Finland. They’re called Saimaa Ringed Seal (according to the Saimaa lake that they live in) and there’s only a few hundred individuals currently living. The seals are called Saimaannorppa in Finnish; funny how the word norppa is quite similar to nerpa. :) Finnish WWF arranges a live cam each May called Norppalive (because that’s when they spend time out of the water to shed their winter fur) and there you can sometimes catch the rare seals lounging on rocks in lake Saimaa. Wonderful and loveable creatures. People in Finland go to great lengths to try to protect them.

[@lib2574]

On a more serious note, when I was there visiting my wife's family, I talked to many people and found out that there are many problems - tourism, litter, water pollution and most frighteningly a "secret" deal between the local Russian government and China to make a pipeline for exporting freshwater from Baikal. Apparently the project is already underway, even though many locals are protesting and sabotaging it.

[@indianasquatchunters]

Noukz37 I just did a quick google search to see if that was true. It seems a few news sites have covered the issue. That’s quiet scary to imagine. If they build the pipeline it will only lead to more pipelines and more water being pumped out. China will use that water to grow the areas that are currently dry, needing more water every year. This seems like a slippery slope. I hope it doesn’t go through.

Good point, however, Saimaa and Ladoga seals are technically considered subspecies of ringed seal which usually lives in the ocean. They're basically populations of ringed seals that have been stuck in fresh water only since the last glacial period ended about 10,000 years ago. DNA studies suggest the ancestors of Nerpa that reached lake Baikal around 400,000 years ago were also closely related to ringed seals. See www.ncbi.nlm.nih.gov/pubmed/14624043

Speaking of Nessie, If Nessie does somehow exist, (FYI highly unlikely) there is a far better candidate than the plesiosaur that people normally envision. Another group of aquatic reptiles the Choristoderes share many of its supposed traits more accurately than plesiosaurs and unlike the plesiosaurs they lived through the end Cretaceous extinction well into the Cenozoic with the last known fossil evidence of them from 18 Mya which is certainly younger than lake Baikal. While I doubt a air breathing reptile could survive there without having been discovered it would be far more plausible than other claims.

Turning your car off while you wait for someone is a nice gesture, but we need legislation against the big polluters.

[@JordanThomasRichards]

Agreed, avoiding taking flights or using any type of combustion engine for transportation will only go so far. They'll still be used countless times despite our best efforts. Change needs to start from the top.

[@eggsngritstn]

You're joking, right? You, the consumer, are the big polluter. You demand transportation, air conditioning, rechargeable batteries and cheap goods from China. Stop asking government for answers.

I have been burning hundreds of old air conditioners, refrigerators, and DVDs of The first Ice age movie in an attempt to please the gods of cold so that they will be powerful enough to over throw the evil tyrants of heat. Each offering brings them yet more strength I can feel it getting colder with each passing day, and the sun sets each night a little quicker. Soon they will rise and smite global warming with their chilling touch.

[@electroflame6188]

Make sure to do the correct rituals; if you don't, you will only please some ice elementals, which the lords of heat will be able to overthrow with time.

[@sethg6157]

@@electroflame6188 your words are wise indeed I will be sure to burn more broken plastic snow globes and first aid cold compresses in my next offering!

[@artcurious807]

Lake Baikal might not be a lake at all but really a sea in the making. I was born near the Great Lakes in Midwest America and as far as I know all geologic activity has ceased and there are no thermal vents. The Great Lakes lakes will be the same in a million years as they are today. But Lake Baikal is growing and geologically active, 2 - 5cm per year adds up over time. It will eventually be the Baikal sea.

I want Nerpas in Lake Superior and lakes all across America. They're so cool. And controll breeding so they don't get out of hand.

[@cosmobane6995]

The reason of Nerpa's existence there is simple: One day, the elders among their ancestors decided to teleport their kin from the sea to the lake.

2cm wider annually? Sounds like my Ex. Kappa

[@jer103]

This staggering fact, threw of my concentration for the rest of the video. Here in the US 2 cm = about 3/4 of an inch. The lake grows less than an inch a year. Wow. Most useless fact ever...

Nerpa is quite possibly the best name for an animal yet.

[@gordonlawrence1448]

Nerpa are curious and cute little fatties. The Lake Baikal natural history museum had one that was rescued and it seemed more interested in us than we were in it. IE watching us go round the museum and talking to the guide etc.
