>A whale fall occurs when the carcass of a whale has fallen onto the ocean floor at a depth greater than 1,000 m (3,300 ft), in the bathyal or abyssal zones. On the sea floor, these carcasses can create complex localized ecosystems that supply sustenance to deep-sea organisms for decades.

I first learned about these streams when /misc/ and Wauf watched them together. Enjoyable couple of threads. Rip eyebro
Occasionally when there's an expedition going on, I'll have them on during work as background noise.

That's pretty neat. Thanks, anon!
Imagine being Bootstrap Bill when he walked the plank on the Pearl. You feel the cold embrace of the sea as you touch the water. The pleasant rays of the sun touch you one last time as you get pulled down. For the first couple meters you still manage to equalize the pressure, but eventually your eardrums burst. It gets darker and darker, and the pain in your lungs gets ever more unbearable. Finally, at about 100 meters or so, you give in. Seawater fills your lungs, and the pain seems to diminish somewhat. Yet as you're immortal due to the Aztec gold, you cannot die. You try to catch the last dim rays of sunlight as the cannonball pulls you into the abyss. Eventually, there's only darkness left.
You keep sinking down in absolute darkness for almost an hour. The pressure starts building up. Your entire body hurts. Your eyeballs feel as if someone was pushing his thumbs in. Your bones hurt as if they were trapped in a hydraulic press. You keep going, thinking what will happen to you next.
Eventually, you feel a slight thump, and notice you've touched the seafloor. How far down are you? You try to look around, but there is nothing to look at. No sight, no sound - nothing. You are alone with your thoughts, for days, months, or even years. We know you'll make your deal with Davy Jones at some point, but you can't know that yet. You might be there for all eternity.
You start losing track of time, of space, yes, even of yourself. Who are you? Are you dead? Or are you not yet born?
Sometimes you notice stuff: strange lights in the distance, of unnamed creatures, perhaps. Dim sounds of whales from far, far away. Sometimes you feel as if something was nibbling at your back. Is this real? Or are you dreaming? There's an eerie silence and total darkness all around you. You start to feel content. You are at peace. Focused. Moisturized. Unbothered. In your lane.
why can't he just swim up too the surface?
His boots were strapped to a cannonball. That's why they called him Beltrope Jack.
When diving deep enough the human body loses buoyancy. Even if you weren't tied to something heavy you still wouldn't be able to swim up at all, like that one video where some guy dives super deep into a blue hole without the right equipment. When he got near the bottom he was sinking like a stone and you could see him walk around for a little bit on the seabed before dying of oxygen toxicity.
>When diving deep enough the human body loses buoyancy.
This, especially when your lungs are full of water.
More important question: How did he make his deal with Davy Jones? Did the Dutchman just happen to run into him one day? Seems extremely unlikely given how vast the ocean is. I mean, if he spent half an eternity down there the probability would eventually reach 1, but we know for a fact it couldn't have been more than a few years, withen him being Will's father and all.
Also, who in their right mind would let a prime Keira Knightley walk the plank instead of keeping her as the crew's wienersleeve?

Here's Ernest Shackleton's Endurance, which was found in 2022, 107 years after it sank, at 3,000 meters below sea level. It appears in wonderfully pristine condition, considering its age.
Imagine the mysteries you could uncover if we could just examine this vessel more thoroughly. It could be little things. An unopened bottle of whiskey in the galley. The graffiti some sailor carved into the wood with his knife while he was bored. Maybe even some coins or personal belongings from one of the men. Maybe one of them carried with him the medallion of his sweetheart back home.
It was so cool hearing that this was found but it weirded be out a little because I had just finished Shackleton's memoir when the news came out.
Weirder yet was the discovery of Erebus and Terror right after I finished reading Frozen in Time which is about the ships and the exhumation of the sailors' bodies on Beechy Island.
I think God is trying to tell me something
I forgot about that show, that shit was cool.

>have to spend decades eating the same old shitty rotten whale
I bet they'd kill for an onion ring
I chose the impossible.
I chose Rapture.
BUT...my city..was betrayed by the weak.
So I ask you, my friend..would you kill the innocent? Would you sacrifice your humanity?
We all make choices, but in the end, our choices make us.
I've never really thought about a whale or fish dying of old age
There's a term for it, "marine snow" or something. It's all the stuff dying in the upper layers of the ocean and trickling down to the bottom: plankton, dead fish etc.
Basically the deep sea is so fricking barren of nutrients that life down there has to cling to the tiniest source of food there is. Which is why whale falls attract so many scavengers. It might be the only time they get to eat to their hearts' content for months of even years.
It's also the reason why deep sea fish move so eeriely slow. They must conserve energy whenever they can.
Why's it so barren of nutrients? Wouldn't everything end up there sooner or later? Or is there just too many nutrient exports further up, so everything gets eaten before it reaches the final bottom?
The problem is that marine snow has to go through multiple layers of increasingly desperate ocean biospheres, and what is left is basically just tiny bits of shit.
I don't know how true it is but I saw a post somewhere stating that whales never die of old age, they just eventually get so old and weak they can no longer swim to the surface and drown
Does that not count as dying of old age? That's not the actual cause of death in anything - old age just causes weakness that results in either a pathogen winning, organ failure, or predation.
I think the difference is if you have a dog that dies of old age it reaches the point where its body is breaking down, whereas a whale that old could probably live several more years if it could just reach the surface
Both are the same in my opinion. Both are about an organism too old to survive in its habitat. A whale too weak to surface (and thus drowning) is pretty much the same as a dog too weak to hunt (and thus starving).
But I'd like to add that "dying of old age" is a strange and nonsensical human term anyway. Like, what's the difference between organ failure (e. g. your heart just stops one night) and let's say cancer? Cancer usually sets in at old age too, so why not count that to "dying of old age" too? It's a weird human term we ascribe to all the cases we deem to be "peaceful" and "normal" and at that age, but at the same time not all of them, etc. It doesn't even make sense for humans so I don't think you can apply it to the animal kingdom.
>pretty much the same as a dog too weak to hunt (and thus starving)
It would be, and while that's age related you'd usually call that death by starvation and not by old age
>Like, what's the difference between organ failure (e. g. your heart just stops one night) and let's say cancer? Cancer usually sets in at old age too, so why not count that to "dying of old age" too?
I think the point is that they never get the chance to die of age related health issues like organ failure and not literally dying because you reached a certain age and your body decided that time is up
Do they speak abyssal there ?
Alas, even the deep sea isn't safe from the destructive influence of man.
Here's a fricking beer can at 3,780 meters depth near the Mariana Trench. It will most likely remain there for hundreds of millions of years until plate tectonics have moved it below the Earth's mantle in untold eons.
If humanity regresses back to stone age levels of technology, as is likely considering our devastating impact on the environment, and slowly builds its way back up to our current technology levels, future humans thousands if not hundreds of thousands of years in the future might find this can and wonder what it is all about. Is it an offering to some unknown sea god? A vessel in which some ritually significant substance was held? Or simply trash some rich homosexual threw overboard while fishing for near-extinct shark species on his yacht?
ali can would only last for like a 200 years, Black personbrain
there isn't a material that would last for hundreds of thousands of years
It's an American planet. Deal with it, nerd.
>Czech beer
>It's an American planet. Deal with it, nerd.
At least one thing will survive WW3, and that is the knowlede of just what a fricking shit taste Americans had when it comes to beer.
Why isn't it completely crushed by the immense pressure of the depths then? Seems like another fake outrage to me
It wasn't full of air
Because inside that can there's also immense pressure of the depths
can you bottle that?
Yes but it would be too heavy to bring to the surface.
I think they can synthesize heavy water (with deuterium instead of regular hydrogen) in labs although it's very difficult. Still easier than trying to bring naturally occurring heavy water up to the surface from the oceanic depths though
that makes sense.
the heaviest water would be at the bottom, right?
Yeah, something to do with the immense pressure compacting the density of hydrogen atoms turning the water from H2O into H3O
i thought it just sank to the bottom cause its heavy, was that wrong lol? XD
Where the frick did you learn that? Heavy water is still H2O but with deuterium instead of protium.
I only drink tritium water

>It will most likely remain there for hundreds of millions of years
do you think aluminum is indestructible?
What exactly would destroy it? The ocean floor is extremely persistent as there's very little currents or meteorological effects like we have on land. The aluminum is covered in an anti-rust detergent. The can isn't food.
As such, it will remain there for millions of years unless it gets picked up by a dredge.
do they dredge at 4000m a lot?
>look it up
>it's real
Can anyone explain to a moron how can a can be that deep without being crushed?
its full of water
pressure is equal
The can is open, the water is outside and inside it. No difference then pinching the inside and outside of the can between your fingers, it would equal out and not move
The Current-Thing crush phenomenon only happens when you descend with your own internal pressure until your structure suddenly gives way, not when you slowly descend with pressure gradually increasing
Booohoo you green homosexual
do you understand the board you're on?
I thought this was just dog frickers anonymous tbh
It's fake you can see the strings.
I can see your strings
I can't see you at all.
Afaik it's a whale carcass deliberately dropped by scientists so they can study the effects of decomposition. The strings are attached to buoys on the surface so they can locate it again.
>scientists beat a whale to death with iron bars to do an experiment
Sad but that's the only way to get results
Those are range finding lasers
I've always found the deep sea deeply fascinating for some reason. Like, we know so much about space by now. We're able to look billions of years into the early stages of the universe, capture gravitational waves of two black holes colliding billions of lightyears away some eons ago, yet we know surprisingly little about the deep sea.
What mysteries can lie there? Maybe there are elaborate cave networks at some underwater mountain ridges which no man will ever dive in. What about all the stuff human have thrown overboard, or ancient ships sinking to the bottom of the ocean. Venture out a couple hundred miles and throw a coin or something overboard. It will forever be out of our reach.
>Stage 1
>The initial period begins with "mobile scavengers" such as hagfish and sleeper sharks actively consuming soft tissue from the carcass. Consumption can be at a rate of 40–60 kilograms (88–132 lb) per day. This stage typically lasts months up to 1.5 years.
>Stage 2
>The second stage introduces the "enrichment opportunists". These are animals which colonize the bones and surrounding sediments that have been contaminated with organic matter from the carcass and any other tissue left by the scavengers. This stage can last months up to 4.5 years.
>Stage 3
>In the third stage, sulfophilic bacteria anaerobically break down the lipids embedded in the bones. Instead of oxygen, they reduce dissolved sulfate (SO2−4) and excrete hydrogen sulfide. Due to the toxicity of H2S, only resistant chemosynthetic bacteria survive. The bacterial mats provide nourishment for mussels, clams, limpets and sea snails. As whale bones are rich in lipids, representing 4–6% of its body weight, the final digestion stage can last between 50 and possibly 100 years.
>Stage 4
>Some scientists postulate a fourth stage of ecological succession at whale fall sites, called the "reef stage". A whale fall enters this stage once the organic compounds have been exhausted and only minerals remain in the bones, which provide a hard substrate for suspension and filter feeders.
Nature is fricking crazy man
mind blown
>The amount of carbon tied up in a typical single whale carcass (about two tonnes of carbon for a typical 40-tonne carcass) is roughly equivalent to the amount of carbon exported to a hectare of abyssal ocean floor in 100–200 years.
fricking Aiptasia man. That shit grows everywhere
