8,500 Feet Deep; The World's Deepest Submarine Canyon

First time seeing you. You are much younger than I expected. Thank you for the wonderful informative videos given in your beautiful modulated voice. 🍀🍀🍀

[@icollectstories5702]

Wow! You missed Iceland??

[@kenbrady119]

Instead of obsessing over the Titanic, shouldn't the undersea explorers be pursuing features like this?

[@b.6603]

As long as the sea explorers are billionaires in poorly made submarines..... I encourage them to follow their dreams to the fullest extent possible 🙏

[@soly-dp-colo6388]

Because the deeper you go, the more pressure there is, and submarines tend to implode...

[@curious5887]

I’m glad you did that face reveal, because there will be people who still won’t stop talking about your voice and someone will think it’s an AI, even though it’s not

[@jacquietigar707]

Thanks for all your hard work ❤

[@ianwilson1302]

I absolutely Love the doubters being proven wrong. This is a geology channel not an AI channel. Geologists all talk this way to contain our excitement about the world and how the planet is structured.

[@maryfreeman3341]

Thank you so much for this accessible lesson about a geological feature I had not heard of. I enjoy geology because of the lessons you have been providing me in bite sized amounts. Thank you so much.

[@TheSpaceEnthusiast-vl6wx]

Thanks so much, Geology Hub!I first heard of the Zhemchug canyon on a video by youtuber Atlas Pro. It is truly astonishing, so it is great that you finally covered it. I hope you can cover more submarine geological features. It is also nice to see you again.

[@earkittycat]

Same

[@bevinboulder5039]

Tim, it's great to see you doing the intro to this video. Very interesting subject too.

[@StuffandThings_]

It freaks me out just how _big_ some of Earth's hidden features are. Whether its massive submarine structures or stuff hidden deep below the crust, its amazing to think of everything that exists on the planet that we never interact with.

[@Orchids.and.Endlers]

Love your content 👍

[@markstott6689]

It's been rather nice to see the face behind the voice. Especially as usually you're stood near a volcano on Iceland, it's mizzling, and your hood is hiding most of your head. I hope that this is a new trend? It's stories like this that make me wish that I could go back in time to witness the geological changes. The area that I'd most like to visit is Doggerland before the sea came. 😊❤😊

[@leyvarecio3699]

That is cool i heard that turbidity currents can break underwater cables

Hallo Tim! Nice to see you!🙂

[@emom358]

Excellent video thanks

[@Baldevi]

I loved visiting Moss Landing [shown early in the video] and we even once were allowed to ur the MBARI Research vessel, which is docked there. [Monterey Bay Aquarium Research Institute] My Ex-Husband and I saw creatures from deep in the offshore trench [can't remember which trench] that were being kept alive by holding them in highly pressurized tanks. Seeing these animals live is something else! I am still grateful that the security guard/researcher so kindly snuck us aboard as he did, since the vessel and crew were having a day off. I love learning about these undersea canyons, how vast and deep they are, and imagining the animals and other sealife hidden there, as yet unknown to humankind. And I think we all appreciated your face reveal, how eager and kindly your expression was; you seemed happy to share this information with us, and we are happy to receive!

[@ruthnovena40]

No! Give us a warning! After listening for so long, I have an image in my head of the narrator. Now it is shattered. (I've tried to ignore the other brief clips) It's like seeing Click and Clack after years of listening to Car Talk.

[@R6AAO]

[@davidsummersong162]

Years ago, I read that Yale University suggested that there was an extinct volcano in CENTRAL New Hampshire. Does this actually exist? Thank you for the brilliant videos that you produce that inform us or of things we would never know!

[@Dragrath1]

Yes the white mountain batholith within the white mountain igneous province are the remains of magmatic plumbing of ancient volcanoes produced when the New England hotspot passed through North America during the Cretaceous. Note that only the igneous dikes and batholiths that fed these volcanoes remain with the composition ranging from syenite to granite the intrusive counterparts of trachyte and rhyolite respectively so extremely siliceous volcanism perhaps somewhat similar to Yellowstone today.

[@rainydaylady6596]

Good to see you without a volcano erupting behind you. This was an interesting video. I enjoy hearing and seeing our world's geology. Thank you. 🙂🖖💕

[@susiesue3141]

Thanks for sharing!

[@scillyautomatic]

Very cool story, btw! Keep 'em coming!

[@just_kos99]

I did a search to see if you've done anything on Hell's Canyon, and if YT can be trusted it looks like you haven't. Since you mentioned the Grand Canyon in this video, it made me think of Hell's Canyon. Also, there're a lot of turbidites off the Juan de Fuca plate boundary that confirms the megaquakes that have happened there, so it was cool you mentioned the "turbidity currents" off this Alaskan submarine canyon!

[@25scigirl]

Interesting video and thank you for an up-close of your face. Speaking of deep submarine canyons, I thought that you may want to do a video featuring some underwater seamounts such as West Mata submarine volcano in the Mariana trench, the Monowai volcano in the Tonga-Kermadec Arc, and the New England Seamounts which are off the coast of the Eastern seaboard. I look forward to seeing these volcanoes in a future video.

Amazing. Never imagined a river valley that continues under the ocean. 🤯

[@John-eq8cu]

Wow that is amazing. I thought that these underwater canyons were carved when the sea level was low, but in this case, you showed how the canyons were carved underwater from the top of the shelf.

[@zyrians]

What about Weber deep? The deepest point in the ocean that is not in a trench.

[@stvrob6320]

Such canyons and undersea "rivers" are being mapped all over the world lately. They are much more extensive than was once imagined.

[@markpinther9296]

haha His voice and face are real folks. Just giving you a hard time ghub. Always enjoy your content and you are my goto for anything geological. Interesting theory about the formation of that canyon. It’s also the same theory that is used to prove the existence of the 9.0 earthquakes off the coast of the state of Washington. Where the two plates meet. Turbidity.. small landslides but these were under water already.

[@W7ENK]

Wait... But Mariana Trench is 10,908 m (35,787 ft) deep. 🤔

[@Dragrath1]

That is an ocean trench not a canyon trenches are where one plate sinks down into the mantle so its a different process of formation. Canyons are erosional features.

[@thomasgoodwin2648]

@Dragrath1 Thanks for explanation. I ♥ the community here. Exchange of knowledge without the usual bulltrollery.

[@hollsee9266]

Be neat if you did a geology segment on the Fraser River Canyon area. It used to be a fault but is stationary now. What else I find interesting about the Fraser River is that during the great floods the deposits it left on the coast to create the Lower Mainland and parts of the Bellingham area all the way down the the Skagit River Valley. 😊

[@carltauber2939]

Not as large or as deep, but closer to home, perhaps you other subscribers would share my interest in hearing what you have to say about the Hudson Canyon.

[@b.a.erlebacher1139]

At one time the Great Lakes drained through the Hudson River because the St. Lawrence was still blocked by the continental ice sheet. With the ice sheet melting, the amount of water draining through the Hudson must have been immense.

[@davidford3115]

If you are going to do a series on canyons, might I suggest both Black Canyon of the Gunnison in Colorado and King's Canyon in California? Also, are the deep oceanic trenches/convergence boundaries steep sided like a canyon or how are the structurally different?

[@tristanmelling410]

Oh, what about the Kermadec Trench and associated subduction related seamounts?

[@richardknapp570]

[@ibeatyoutubecircumventingy6344]

that looks an awful lot like a River Canyon we have similar Topography undersea off of Fremantle Harbor where the Swan River enters the sea but if you lower that sea level back to full ice age periods! is a map or aerial photo or something that while not so fantastically deep gives a good reason and accurate equivalent for the depths of the Ocean a wee bit back in Time when we had Glaciers Everywhere and everyone was huddled in the equatorial regions working on their Tans!
