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

There lies a hidden canyon deeper than the Grand Canyon just offshore of Alaska. There, the Zhemchug Canyon is submerged underwater, but encompasses a vast ravine which is up to 8,530 feet deeper than the adjacent sea floor. This is the story of how this magnificent canyon formed in the Bering Sea, and how its formation relates to the Yukon River.

    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!

    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.

    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!

    Thanks for the brief glimpse of yourself. I've come on board a little over a year ago and find your podcast informative and interesting. Keep up the narratives. This podcast, brought a persistent dream to mind" by the year 2110 the earth landmass will have changed. A large swath of east coast USA will be subnerged as will the UK and surrounding islands. New land masses will arise in the southern Atlantic and Indian Ocean and central south pacific. India's west coast wil also be submerged as will the Maldives, Diego garcia and Seychelles. Alaska, kamchatka and the russian land mass will be reconnected." I hope a few of your subscribers will be witness to it. Many will experience the beginings; in two decades, gathering steam over the next three decades; I will be gone before it starts.
