20 People Online Share Obscure Facts About The Ocean That Show How Little We Know About It

Published 2 years ago

It’s amazing to think that humanity has explored the solar system, and is even aiming to go beyond. But when we look at our own home, it seems that we have barely scratched the surface. Yes, I mean that, literally, we haven’t explored much of the deep sea, and our understanding of it is just surface level.

To feed our curiosity about the vastly undiscovered ocean, we went to the Reddit thread by the user this_is_not_me_6. There, netizens went to share spine-chilling facts about the ocean that not everyone might know about. So prepare to learn 20 disturbing new facts that you’re probably better off not knowing in our list below!

Lost sailors in the sea who cling to wreckage basically have their skin dissolved by salt water after soaking for more than 3 days.

There are parts of the ocean which are dead no oxygen in the water which means nothing can survive, no fish no plankton nothing at all. They are spreading exponentially. Whilst they are tiny now and have been. At the rate of growth. They’ll cause serious problems before the end of the century.

When sea creatures die in the ocean and their bones sink to the deep ocean floor, zombie worms eat the bones. The skin secretes an acid dissolving the bones, digesting the remaining fat and protein left behind.

94% of the Earth’s oceans are just pitch black darkness.

I remember watching a YouTube interview with a military diver. He described how when you’re doing a covert op you spend a lot of time just underwater doing nothing with no lights on until it’s time to move.

He specifically mentioned how he had to get used to having large things bump into him in the pitch black.

I’m a scuba diver and one thing that really scared me when I first started off diving, you hear SO MUCH more underwater then you ever will above on the surface, I’m not even talking about like the shifting or just the water itself moving, your hear things like fish clicking and other things like that, cuz underwater sounds move and travel a lot more so you hear a lot more and much quicker, was pretty out of nowhere when I first went under

When you dip your toe in the water you are no longer at the top of the food chain.

We don’t really know whats it in I can say that for thousands of years we drew sea monsters beliving they lived in it. Surprising alot of stuff we found in those pictures were in the ocean. (Giant Squid recently ). Just makes you think what else is actually down there that we don’t know about.

Only 5% of the entire ocean in the world has been discovered, that means that there is still 95% unmapped.

“Hot tub of despair” is a lake under the ocean, in the gulf of Mexico. It is highly concentrated with salt and has dissolved methane. Any creature that enters dies.

It doesn’t hate you. It doesn’t love you. It doesn’t even know you exist. When it destroys/capsizes your boat your boat didn’t even cause a change in its movements.

I am a sailor and I am in love with a cold heartless b***h who couldn’t care less whether I live or die.

Ocean Acidification.

Increasing concentrations of atmospheric carbon dioxide (CO2) lead to higher concentrations of dissolved CO2 in surface seawater. This results in ocean acidification, which may affect the growth of the photosynthetic phytoplankton that form the basis of marine food webs.

So, total marine ecosystem collapse due to greenhouse emissions, the ocean produces more than half of the oxygen on earth, so that doesn’t bode well for us.

Point Nemo is the most isolated place in the world. It’s in the middle of the South Pacific gyre, which is a massive rotating current that basically keeps any nutrients rich water from ever getting in. So there is no sea life anywhere to be found except for a few crabs and bacteria that live near some thermal vents on the ocean floor. It’s so far away from any land that if you sailed there the closest people would be on the international space station. This is the location HP Lovecraft was describing when he provided the location of R’Lyeh where Cthulu and the other old ones love, although Lovecraft’s coordinates were slightly off.

And in 1997 the loudest unidentified underwater sound ever recorded, known as “the bloop”, originated near there. It was loud enough that it was recorded from multiple sensors 5000 miles apart and lasted for over a minute.

The prevailing theory is that it was ice cracking off the south pole but we don’t actually know what caused it for sure.


Once you get to a certain depth your buoyancy changes and you actually start get pulled down instead of floating up

The Gulf Stream is created by the melting of ice from the north polar ice cap. That ice cap is rapidly disintegrating. Once it’s gone, the Gulf Stream is gone. Once the Gulf Stream is gone, the weather pattern for the whole northern hemisphere dramatically changes.

This will be catastrophic.

Well Crippin should have dumped his wifes remains in the ocean because not an ounce of food goes to waste including the bones.

If you need to get rid of a mass grave don’t bury dump at sea and the entire body will be eaten which will actually be beneficial to the ecosystem as a whole.

We shouldn’t be burying people but dumping them at sea.

This story is corroborated by the survivors. During one of the world wars, a ship was sunk and 11 survivors clung to a lifeboat until one of them was dragged down into the abyss by a “cephalopod”. If he wasn’t killed by the animal’s beak, he would have died a horrific pressure death while the cephalopod probably rapidly descended with it’s life prey. It’s not possible to say which species this cephalopod belonged to, but the Giant Squid and Colossal Squid are the largest and heaviest known so far. And some scientists speculate there might lurk an even more massive species of cephalopods deep down in the ocean.

And whenever you sail by boat and look down into the deep blue darkness of the ocean, remember that the probability will never be zero to be suddenly grabbed by one and dragged down into the total darkness, dying a horrible, horrible death.

Depending on the person then this could be scary or really cool.

Oceans can have underwater oceans, rivers and waterfalls. Due to different water temperatures and density and all that scientific nonsense.
