Seamounts are important deep sea ecosystems. Breaking the flat monotony of the abyssal plains, these underwater mountains emerge from the mud. Those that rise less than 1,000 m (3,000 feet) above the plains are called abyssal hills, while anything taller is a seamount. And there are at least 100,000 of them, with over half found in the Pacific Ocean near the tectonic plate boundaries. An unsurprising statistic, for Seamounts are formed from volcanism. The same process responsible for the formation of many island chains. At mid-ocean ridges, the converging tectonic plates collide at boundaries called subduction zones. One plate is subducted, or forced down towards the Earth’s molten interior. As it is subducted, the crust melts and becomes magma, which rises through the rock and erupts to form volcanoes and seamounts.

Documentaries like this are what attracts people to study more about our world. It's a shame that so-called documentaries no longer produce content as good as this. Keep up the good work man. You might as well pass the torch of knowledge to the younger generation 👍

man, what I would do to be a 100-year-old piece of coral on the side of David's Seamount, 10,000ft underwater

i'm a marine biology graduate currently on a gap year before starting my master's, and your videos spark the same joy that made me pursue marine bio as a career in the first place 🥰 excellent work as always, excited to see more!!

I don't think it's an exaggeration to say that you are producing some of the most fantastic content on this entire platform.

I (29) have been watching documentaries for as long as i can remember. A narrator can make or break the entire show sometimes, and I gotta say you do an incredible job at narrating these videos. There's an ethereal quality to it and it works especially well with underwater themes. I've never become a member to anyone on youtube but I'm starting now with this channel. This sort of quality is so hard to come by and I want to see more.

You used the Journey soundtrack! One of my favorite soundtracks ever and one of my favorite games ever, nice to hear it here!

words cannot describe how much I love this style of narration. the calm, sedating voice, but interesting and captivating topics and images are just so enjoyable. no BS, no stupid cringy forced jokes, no over the top editing, nothing. it just finally feels like a genuine and real video <3

I'm a submarine volcanologist and this is AWESOME! You really captured what it's like to be down in a submersible looking out at this beautiful other-wordly landscape. Axial Seamount is a super cool seamount off the coast of Washington that is home to the first ever cabled array (live data, footage etc) coming straight from the seamount- check it out if you haven't already you'd like it! Thanks so much & can't wait to watch more!

I couldn't even begin to imagine blindly diving thousands of feet and just - out of sheer chance alone - that place HAPPENING to be a nursery of hundreds of mama octopi and their thousands of eggs.

Love that you’ve brought attention to these ecosystems. The deep sea is extremely fragile, unknown, and very much under threat. The only reason sea mounts haven’t been mowed down for their cobalt is because it’s currently technologically impossible. That’s not the case for the manganese nodules and methane seeps located in the abyssal plans and deeper... as a science communicator, you’ve done great. As someone who studies the ocean as my job, I genuinely enjoyed this and didn’t feel like it was too elementary or too complicated. And yes, the inclusion of Austin Wintry was a solid decision :).

The narrator has the most soothing voice for nature videos. And also sounds a lot like Cole from Dragon Age 😂

I instantly recognized the Journey soundtrack, coupled with the soothing narrator it's impossible to ignore.

They are like the monasteries of Mount Athos, or the temples and shrines of the Himalayas! Without the mountains, these sea animals would have no community. That must be what Sir Attenborough meant when he called them "cities"! It's another triumph, Leo! Thank you!

I'm so glad that your talking about the ocean. It feels like that we only talk bout th ocean when it comes pollution. It's kind of sad that there are less people willing to study something on our planet and want to go to space for new life, even when haven't found most of it on our own planet. We look for aliens in space but never think about them being in our ocean.

This is so beautiful, I study animal medicine so I previously considered the ocean only for its flora and fauna but you have expanded my view to see the landscape and environment full of variety and colour. Thank you
