The geological origins of cold seeps differ from hydrothermal vents. While vents form from volcanic activity at sea-floor spreading regions, cold seeps instead arise at the other end of oceanic plates, where they are subducted at the continental margin. Their formation begins with the burial of organic material under sediments on the sea-floor. These organic compounds degrade over time, producing methane. Over time, geological processes such as the tectonic compression of sediments at subduction zones forces the methane from deep reservoirs up through the overlying sediments. Anaerobic microbes dwelling below the sediment surface oxidise this methane using sulphate, producing hydrogen sulphide and bicarbonate ions as a byproduct. This hydrogen sulphide, along with any residual methane, then serves as a vital energy source for *chemosynthetic* microbes. Thus, it is a consortium of two distinct sets of microbes that makes primary productivity possible at cold seeps and lay the foundations of food webs here. The result is an environment remarkably similar to hydrothermal vents. We have a flux of sulphide and methane at the sea-floor, chemosynthetic microbes using these compounds, and an abundance of life exploiting this primary productivity, fulfilling similar ecological niches and forming biodiversity hotspots in the deep sea.

great video i Subscribe.,..
We need to find where the giant and Colossal squid 🦑 live
Thanks so much, always an amazing journey 🌊🚣♀💭💡
These videos are always such high quality, and his voice is always so soothing! The perfect thing to watch after feeling stressed, or to fall asleep to!
I’m so glad ☺️☺️
@@NaturalWorldFacts in the next video randomly scream to wake up all the people who fell asleep
@@grim_blazer9120 🤣
I'm not sure how to feel about people falling sleep to an educational video
@@hanwenhengliu3776 Lol I know what you mean, but I must confess I do this too. Only with educational videos. I can only fall asleep to these videos once I've watched them a few times and it's like hearing a very familiar soothing story that is interesting but predictable because I've seen it. I just relax into their voice, which also has to be good like this man's voice is, and then fall asleep. I can only do this to very good quality content, so it's no sign of being bored or not being engaged by it either.
The thing that fascinates me so much about hydrothermal vents and cold seeps is how much they show that our planet, even far below the surface, is alive in a way and creating life all the time. There is very little footage that is more satisfying to me than a cluster of tube worms extending and contracting their frills. Another amazingly entertaining and educational video. I am really looking forward to Part 3 of this series. Thank you so much for all your hard work to create such high quality content.
it is kind of crazy where we keep finding life. I've heard of some bore holes like the Kola deep bore hole that found invertebrates hundreds of feet below the surface and microbes as deep as 1400m/4600ft. They've found microbes and even spiders flying in the upper atmosphere.
for anyone like me who was heartbroken at 12:45 ,,, i read somewhere that the layer that forms is usually not very thick unless they sit there and keep agitating the bubbles, and generally they can scrape the icy layer off, so it's not doom for them, just a weird little experience :')
and yes i full on got my heart broken because the crab looked so shocked and i was worried for it ok xD
Yesss me too :( I felt so sad for that crab but I'm glad you gave the extra info!
I LAUGHED SO HARDDD THE MILK MUSTACHE
I mean sometimes you need to disassociate your feelings when it comes.to nature. I remember a great analogy that a comedian made that when watching nature documentaries, in one episode the gazelle is trying to escape the cheetah hunting it (in which you wish the gazelle to get away), and in the next it shows the cheetah had cubs and is just trying to feed them (so then you support the cheetah..) lol. I realise that cold seeps are different but my statement stays the same that when it comes to nature, best to disassociate your emotions.
Heartbroken?? For a crab? You do realize there are 4,500+ crab species and 272 million of those are jus tone species? Yet your heartbroken over a single one? Come on. That’s just nature. The natural order. Everything dies.
Cold seeps make me think of extraterrestrial environments capable of sustaining life forms. The possibility of finding life under the frozen surface of Jupiter's moon Europa is the first thing that comes to mind. *yes, the hydrothermal vents here on Earth are also incredibly fascinating. I'm not playing favorites!
Yes yes yes!!! I have my fingers crossed for the future Europa missions
Given the insane number of stars with our own, smallish galaxy, pretty much most with exoplanets, you don't need a degree in probability mathematics to consider life elsewhere is a given, regardless of the form it may take. The mind truly boggles!
Another great documentary with outstanding narration 🥰
Thank you ☺️☺️ I love your films!!
I’m not the type to comment things like this normally, but hey it can’t hurt. I’ve recently gone through a tough breakup after moving to sunny South America with my boyfriend, meaning I’m losing a lot of my new life and about to be moving back to our miserable, gloomy little island of a home country, a prospect which terrifies me and in recent times left me feeling down enough that the unthinkable became a possibility. But then, I found you and your channel, and for the first time in so long I’ve felt that warm comfortable feeling in my chest again, every video is a trip to somewhere more peaceful and quiet where I don’t have to think contemplate, fight or question anything. Just peace. So genuinely from the bottom of my heart (and as a fellow Brit), thank you for all that you’ve done here, you’ve helped someone begin to get out of a very dark place.
I adore the fact you can watch each episode individually without having watched the others. You always set up the basics in such an easy way to understand, great job!
I found this channel yesterday and its all ive been watching since! Cant express enough how amazing the production and research for these videos are. And all the footage!! Who knew a place that seems lifeless is so colorful and active!?!
Thank you so much for this ☺️
Oh, I've been positively obsessed with your videos about other marine ecosystems (especially the brine pools) so I'm thrilled to watch this one!
Yeah that brine pool video is dope. I've watched it so many times! I can't get over how naturally talented this kid is. It's pleasantly baffling.
It’s so amazing that the animals living at both some of the hottest and coldest environments in the world are so closely related.
This might be a small detail for many other people but thank you for removing the high pitched beeping sound from your transition graphics. They always startled me and felt like a jarring contrast to your soothing voice and the music.
agreed
Excellent presentation, as ever. Really admire the quality of your productions and your ability to present some complex processes simply and accurately. Outstanding channel Leo 👍
Why does this only have 73K views? This level of production quality deserves SO much more.
I really appreciate that :)
Yet another fantastic view of seafloor habitats! Beautiful footage, great music, and I love the captions on the screen. This series is on par with the best nature documentaries I have ever seen. Please continue your important work!
While recovering from several surgeries, these videos were how I kept my sanity. I still come back to your channel often, at the end of a long day to relax and unwind. Thanks for awesome content!
It's almost like deep sea trawling is a fundamentally flawed means of fishing which inevitably contributes to the collapse of its own source of revenue, and you know, the rest of the biosphere. While other forms of fishing can be done sustainably, you can't sustainably fish when the bi-catch plucked from nets consists of entire ancient ecosystems.
OTOH it requires almost no brains to run a trawling operation, so there's that.
Another incredible documentary filled with stunning deep sea life and mind-boggling reminders of what a complex and delicately balanced system this beautiful planet is! Thank you, Leo, for the time and effort you put into making these videos!
Some of the best content on youtube, literally just, some of the best.
Thank you so so much ☺️
Such a great episode / upload they seem to get better every time. Thank you so much for you and your staff's work I much appreciate.
Good job Leo! Yet another great video. Your videos have not only been always informative and beautiful to watch, but your pacing and tone of voice has helped me sleep and relax on so many occasions! Keep up the good work man 😀
Amazing video as always Leo! The Tar Lillie's segment especially engrossed me, your editing there was spot on and really encapsulated how incredible the formations are.
I always get so excited when I see you've posted a new video!
This is exactly the type of high quality, original & endlessly fascinating content that keeps me coming back to KZhead... absolutely brilliant! Immediately subscribed. Bravo! 👏 💙
I've been waiting for you to upload a new video ever since I found your channel a few weeks ago. You have the most amazing voice; it's so soothing and calm. I originally thought I had stumbled across another documentary channel until I saw your tidal pool video. It's honestly adtounding how well made your videos are. I wish you the best in life, and now I'm gonna watch this while I lay in bed. Probably gonna pass out, lol.
Dude the production of your videos keep going up, surpassing mainstream docuseries, I love it! Keep up the good work my guy!
watching your documentarys is such a delight. your calming voice paired with the almost unheard knowledge you present feels like a dive itself. thanks for your work
Always nice to find information of such high quality on youtube, thanks and keep it up.
Ahh, a new video! And the same high-quality images and narration, combined with the narrator's soothing, relaxing voice make this yet another winner from Natural World Facts. Thank you for another great video!
Thank you always for such informative & great quality videos!!!
Thanks so much for watching!!
Love your channel! I have learnt so much about the deep sea. I have always been facinated by deep sea and the quality of your vidoes is wonderful. Great job!
Leo, I'm going to keep saying it, you are providing quality documentaries way beyond anything seen elsewhere. Thank you
I love every single one of your videos. The presentation is tip top, from narration to music, to content.
Definitely my favorite channel at the moment, great work man!
Peculiar how Natural World Facts doesn’t have even more followers! Amazing content 10/10💯😎
Great job on the video! I’d be lying if i said that i didn’t enjoy your nature content, but just as well you can read to me any book’s table of contents and i’d still give it a like.
Thank you so much for this! Up next, a 3 hour video of me reading the dictionary 😂
@@NaturalWorldFacts ....🙈 I'd buy that! 💯
wonderful video with such relaxing narration.
this video of the deep abyss have brought me such peacefulness. thankyou. the bg music and the voice the editing everything is pure bliss
Thank you for making these
Always impressed with your work & narration.
Another masterpiece!! Thank you so much for making these!!!!
i keep having severe panic attacks and this channel is one of the few things i can focus on to calm down that doesnt overwhelm me. it helps reminds me that even if i die suddenly, everything dies eventually, and yet life as a whole continues on.
fantastic video :DD twas a refreshing watch after school💗💞
Awesome creatures in an equally awesome environment. Thank you for producing yet another wonderful documentary coupled with a masterful and soothing narration.
I love watching these as I draw, I would for you to make some documentaries taking place in shallower more tropical waters, I know deep sea can be more interesting because the creatures and relationships are so different, but tropical regions have interspecies relationships of great complexity too, I would love for you to cover it.
i always get so happy when you upload
that was fantastic. so well done. nice work.
A lot here that I've never heard of before. Wonderful presentation!
I'm here early! I'm also quite xcited to watch another thoroughly entertaining & impeccably produced video from you, Leo! Your content continues to evolve; gaining such sleek... elegance, with each piece of work you complete.
Thank you so so so much, Lauren, you’re always so supportive, it means the world! I really hope you enjoyed this one, it was so much fun to explore these ecosystems in a video!
@@NaturalWorldFacts Oh! It's truly a pleasure being a part of such an articulate and intellectual community. And, you Sir, are a terrific human. I can just tell! 🤗 I'm only 10 minutes in, and I do believe I've acquired a few more quotients already! 😉
Exceptional productions Natural World Facts. Thank you.
Beautifully made and narrated.
Oh baby I'm early. Love ur vids man, I often use your soothing voice to fall asleep.
I never saw the notification for this!!! So happy I found it!!
Lots of new info in this video. Thank you :)
thank you for your videos!!! So informative and the quality is amazing!
Subbed immediately! Thanx so much!
Love the music at 13:07 LEMMiNO used the same thing on his most recent video, and I got to say you and him are the best documentary KZheadrs
Love your videos, keep up the amazing work.
Amazing, i always hit like even before watching the video!! I dont care, your channel is just my fav
i hope we get deep dives on the types of seeps!!! i really wanna see more videos like the brine pool one!
Thank you for another beautifully done video! Best wishes to you!
Thank you for such high quality educational videos. You are a blessing
You uploaded this at the perfect time. I've had such an exhausting day - this is the perfect reward! :D I've wondered how the gases actually formed. Since these communities take so much methane out of the system, I appreciate them even more. And I love these tubeworm bushes! It's fascinating how many similarities there are between some vent and seep communities. Evolutionary convergence at work. 11:50 The visuals in this video are so captivating. I haven't seen anything like this yet. 14:33 oh, so THAT'S a tar lily. I thought they were some life form. xD I immediately had to watch the full NOAA footage. Man, I'm so fascinated right now. Like a little child. Cold seeps have been among my favorite deep sea topics recently, so it's no surprise that this is my favorite videos of yours so far. ...and then you announce woodfalls. Can't wait. :D
I love soundtrack to this video. The track played around 13:30 is great. Very hip and chill.
Great documentary with amazing narration.
Amazing high calibre documentary! I originally put this on for background ambience for a rainy Sunday but you had my little one year old sat calmly with his ocean books and pointing up at the TV when the crabs come on the screen (they're his favourite). Thank you x
Well done again!
Great video thanks, this is the 1st video I've seen from this channel, and well it's a no-brainer,...I'm subscribing!
Thank you so much ☺️☺️
@@NaturalWorldFacts No worries. I give credit where credit is due, and thank you so much for your reply
Ur channel keeps blowing up GJ
This taught me a lot. Many of your vids, I already knew the what you spoke on. This time, whoa.
Dankeschön für deine guten Videos👍🏼
great documentary, very nice information. Thank you
Thanks so much Felix :)
These videos are so good, thank you for making this ❤💖
I always get excited when I find one of these videos.
I really hope you enjoyed! I have a full playlist of more deep sea films like this if you’re interested? :D
@@NaturalWorldFacts yes please! I’d be delighted.
Can I just say, you have one of the most beautiful voices I've ever heard 😌 It's so easy and relaxing to listen to you. Might just add some of your videos to my anti-anxiety playlist. Doesn't hurt either that one of my favourite topics is underwater things.
I love your channel. Outstanding content. I could watch your ocean videos all day.
Great video!
These videos are extremely profound. The evolution of geology/bio/chem/the universe is profound. The videography, music and narraration give me chills, and immediately impart how profound this is. It makes me euphoric.
This has made my day!!! ☺️
Thank you! I was wondering if brine pools and cold seeps were the same! Amazing video as always.
I love your documentaries, your voice is similar to a young David Attenborough kinda, perfect for relaxing after school!👍
This is like Astrum but for under the sea rather than above the skies. I love it
Particularly interesting one, thx once again!
Cheers :D
great video, i love the music!
Well, this is the coolest thing I will likely see today! Thanks.
The 4 stages blew my mind. The biosphere is wild. Thank you for the fantastic content
Mazeballs! So interesting and so well written and produced and a joy to watch. Bravo sir! Keep 'em coming please :-)
Just had to rewatch this, since I'm interested in both hydrothermal life and that at cold seeps. It's such a fascinating environment. Your videos are part of what i refer to as my "free university". I leaern something new with each video.
Your videos are almost too good. Thanks for the quality content.
Hello, there. Thank you very much for your videos. I have a question that is do you have any video covering only corals and how do they form the symbiotic relationship with others? Because your explanations are very clear. Thanks
The deep sea is truly an amazing place! It is easy to see how life began in the deep ocean when you learn about all the different forms of life that thrive in such harsh conditions. Thank you for sharing these videos; I may not be studying marine biology but if I decide to, I will use these videos as a prime example :)
This channel is so amazing at what it does and I love it Also this video was very great
I've just today been recommended your channel today and it's kinda cool. You remind me of Attenborough but your voice really carries an emotional depth that Attenborough doesn't. I do wish you had more content of this video, 20-30 min, though I understand that takes more work then I might realize but I am drawn to the longer videos so I can see and hear as much as possible to learn. Your a good "teacher" for explaining nature. Have you thought of bundling a couple videos together of, let's say, slow worms or toads. It creates a longer video, with more info. More ad space, longer vids to boost yourself in the algorithm? Just some suggestions but if you take none of them, that's cool to cuz what you have here is entertaining, informative and are beautifully produced. Either, you got a new sub!! Lol.
Thank you so much for this. To hear that my videos and presenting style can reach you in this way is truly a dream come true- my one goal while growing up, digging for woodlice in the garden or watching Attenborough on the telly, was to someday present my own films and spread my passion for wildlife with others! You’ve made my day :) It’s funny you should mention a film about slow worms and toads, as I’m working on exactly that! I recently got a new 4K camera and a tripod, and I’ve spent most days these last few weeks out filming in the UK’s new forest and acquiring hours worth of footage of the woodland environment, log piles, insects, innumerable toads, and slow worms, while presenting on-camera and on-location! I’ve just began the editing process and it’s looking like it may be 30-60 minutes when finished. I may cut it up to make up for how long it’s taking, but I’ll release it in its entirety at first now that I’ve heard from you that you’d enjoy that length of content :)
The combination of hushed delivery and somber music always makes these feel so solemn, and that's kind of a cool approach for this kind of material.
Your work is excellent and challenges the programs I watch on the Animal Planet network. I still can't believe how young you are. Can't wait to see your documentaries on National Geographic channel
So well done! :)
Nice! Another video drop!
I have always wanted to ask this, how do you make all of those cool animations? And where do you find all these awesome clips? I’m interested in making similar documentary style videos and would like to learn more about video making on KZhead related to nature documentaries.
Top quality again !!
thank you for making this amazing video!!!!
Your next episode would be very interesting for me because while I've seen several videos about whale falls, videos about deep sea communities around shipwreaks is a lot less common.
