The process of chemosynthesis is similar to photosynthesis. Both can be defined as the creation of organic matter from the fixation of inorganic carbon using energy. But what differs is the source of that energy. In parts of the deep sea, primary production is fuelled by chemical energy, rather than energy from the sun. But this can only take place at certain sea-floor environments where the required chemicals are released into the water. The two main examples of such environments are hydrothermal vents, and cold seeps. The former were only discovered in 1977 when scientists were exploring an oceanic spreading ridge near the Galapagos Islands. What they discovered was a hidden world that revolutionised our understanding of how and where life on Earth can exist. Since then, hundreds more vent field have been discovered, often at depths of 2km or more, along Earthâs convergent plate boundaries and at sea-floor spreading regions where the oceanic crust is moving apart.

This couldn't have came out with better timing. Just started my lunch break, so now I get to relax, eat and enjoy some awesome deep sealife.

Geologist here, I absolutely love this channel and its really great footage.
One mistake I'd point out tho is that hydrothermal vents are not found near convergent plate boundaries, they're found in divergent plate boundaries.
See : the divergence is caused by crustal thinning near Medio oceanic ridges, this cause a very high geothermal gradient that allow hot fluids to form in the oceanic crust.
Convergent plate boundaries, aka subduction zones and collision zones are generally lower geothermal gradient

I dream of moons of Saturn Jupiter's moons having ecosystems like this in their sub surface oceans. Since they've proven to have huge heated water geysers on the surface, so that proves there is a heat source, and heat, power source under the water there, it's awesome đ

Leo, this is so cool. Between the narration, and the footage, and the illustrations, itâs really impressive. Your bio says youâve been doing this for a decade and it definitely shows with the quality of your content.

Finding high quality documentaries about nature, especially the ocean, Is a tall order more often than not, so the accidental (and serendipitous) discovery of this channel was like manna from the heavens. I can't tell you how much I appreciate and respect the time and effort you expend putting these videos together, as well as your willingness to share them. Always looking forward to the next installation.

As a researcher I often find myself looking for channels with relevant scientific information. I can say without a doubt that this channel is one of the best. The amount of information, the way you explain everything and the little explored theme gives me chills everytime

I have severe insomnia and this video has helped me actually fall asleep. This is a massive deal for me, so thank you for creating such relaxing, informative content.

This channel has genuinely inspired me to pursue my childhood dream of becoming a marine biologist. Found your channel about a month ago and I have seen every single video at this point. Best YouTube channel out there. Keep it up!!!!

Your voice is otherworldly, every time I listen to your videos I go into a trance. Its like sudden onset hypnosis, you could probably tell me to do anything and Iâd do it. Iâm glad youâve chosen to use your powers for good rather than evil, good on you.

The amount of joy that I get every time you upload is unfathomable. I absolutely adore the ocean and your videos give me life.

I'm so happy the algorithm blessed me with this video! I did a school project on hydrothermal vents around 2007 and found it to be fascinating but incredibly frustrating as there was very little information available. I could tell there was a beautiful story there, but I was unable to see how it all fit together and ultimately I was unsatisfied with the story I presented in my project. Watching this video is like a dream come true. Impossibly satisfying. Thank you for telling this story in such a beautiful way.

This video was so amazing, but then again I love all of your videos! I am particularly fascinated with deep sea vents. I think they're my favorite deep sea environment to learn about. I remember watching a documentary about them when I was young, back in the late 70s or early 80s and they were a brand new discovery. I think that was the first time I really understood how much we still have to learn about our planet. Thank you for your amazing and entertaining work!

Poetic narration combined with excellent moving picture - your channel is what the History Channel should be.

It's absolutely remarkable what images the technology of today can get us. Just imagine, decades ago people would have a hard time to even imagine what the depths of the ocean or the surface of other planets in out solar system looked like, and today any average Joe can look up pictures or videos of either. Truly amazing...

Just wanted to say that of all the many many nature channels I follow, I think you've managed to become my favorite over the past few years. The quality (and relevance) of the 4k footage paired with the perfect background music and soothing narration serves as an excellent medium for your delivery of fascinating concepts and explanations of life we may never get to experience in person. Personally, my favorite videos of yours are the phylum and biome overviews, but I still watch everything because it's all top tier content. Love your channel man, I look forward to seeing your journey and learning tons more about ocean life!!

When i was younger i use to watch nature show on PBS and public access channels with my father. Watching this now bring back the feeling

A number of my students have asked about the possibility of life on other planet, and I've tried to get across the idea that it's likely to exist in our solar system with water oceans being confirmed on at least 2 moons (europa and encelidus). I've been looking for a video like this to help with explaining chemosynthetic life, so thank you for putting this out

I cannot get over how beautiful this is. The cadences of your vocals, the music and the clips; absolute perfection, in my opinion. Brilliant job!

Fantastic, as always, and well worth the wait! The beauty of the deep sea always astonishes me. It's hard to remember that all of this exists in utter, complete darkness except when a rover lights it up. Thank you, Leo, for another great video!
