Deep Oceans - Abyssal Plains, Trenches and their Bizarre Life - Biomes#12

- Oceanography - the nature of the vast oceans and their ecosystems. The largest of the world's biomes is the one we know the least of. Crushing pressures and the vast extent of the abyssal plains of the oceans mean we know more about the surface of the moon than the depths below the water. What we do know, however, is life here has evolved into an almost alien-like form that differs greatly from that of the surface. Join me in this final episode of the Biomes series, as I investigate the nature of the deep oceans and their bizarre ecosystems.

The average depth of the oceans is about 4000m, where no light reaches, and a cold, still world exists, totally dependent upon organic debris falling from above to provide food for its strange inhabitants. After descending from the continental shelf via the continental slope, most of the ocean floor is in the form of abyssal plains. However, mid-ocean ridges, where new crust forms, are at shallower depths, while deep ocean trenches descend to as much as 11000m, where pressures can reach 1100 atmospheres or 16000 psi.

The vast flat surface of the oceans act as generators for the world's weather, and storms that form over the ocean in specific regular places lead to the formation of ocean currents that in turn shape global climate patterns, such as the Gulf Stream warming Europe, or the Peru Current creating the Atacama Desert. These surface currents are augmented by an even more complex conveyer belt of deep ocean currents that can be traced all around the world in what is known as the Thermohaline Circulation.
But in general the deep ocean is very still and cold, since cold water sits below warm surface water. The temperature of the water plummets suddenly at around 500m in depth in what is called the Thermocline.

In the absence of light, there are no plants, so most of the biomass in the deep sea is in the form of animals - fish, crustaceans, cephalopods such as squid and octopus, starfish and adventurous mammals - the whales. Many of these creatures use bioluminescence to lure a mate or prey. Gigantism is also a feature of many of the animals here, with crabs and squid, for instance, being much larger than their surface water cousins.

At mid-ocean ridges are found chemically rich hydrothermal vents that allow bacteria to build organic matter from. In turn these bacteria act as symbiotes for tube worms and other life that provides the only biome on our planet that is not dependent upon photosynthesis.

What a beautiful video! Thank you for sharing :)
And so are yours!
By far, your videos are among the most informative videos that I've found on ocean biomes, great work!
Thanks v much!
Thank you for reminding us of how beautiful and complex our world truly is .
My pleasure!
Thank you so much! For filling out the gaps in so many areas, studied and consumed so much over the years and your channel is one I go back to a lot. Amazing really.
Best regards from Sweden.
You are so welcome!
Thank you so much for this intensive and concise series outlining the beauty of our planet. You have inspired me to research ecology more during my free time. Thank you again for sparking my interest towards learning more of the beauty of natural ecosystems. As well as spreading awareness in an effort to protect and safeguard this beauty.
Wow, thank you!
This is amazing! But very underrated, hope you continue with more series! I'd love to see what's next
Greetings from Costa Rica.
Gracias!
Fantastic series! the quality of your videos is stunning & one of the best on TH-cam!
Thank you very much!
Such a beautiful end!
Looking forward to you next series!
Amazing video series! High quality and very educational.
Perhaps you could make videos on the underground "biome" and the island / archipelago "biome"?
Loved the series! What a worthy last part
Another great video. Looking forward to the next one
Hello geodiode☺💙!
-such a beautiful video and montage;
All is said about the quality and beauty of your work, just want to say thanks for sharing your perspective of art through science in these videos.
As these episodes are like a story telling in sequence at the end I felt the same sensation that I felt in the final part of "Icecap" episode... No better way to close a series.... Thanks Master! 👏👏👏👏
Thank you, again, Richard for all your help in this series in finding sometimes hard to find videos of special biomes
@@Geodiode Always a pleasure helping you!
I'm glad I stumbled upon this channel. I'm looking forward to seeing more.
Welcome aboard! You're in for many treats
Suddenly I remember all of my biologics lesson at my classrooms. I love these subjects
Glad you do, thanks!
Thank you for the update this video
it was informative ❤️
BRAVO!
Im excited for the future of this channel!
Another amazing video! 👍
Thank you for changing my life
Amazing!!! Your hard work is present in every video you produce. What are your next video plans if you don’t mind me asking?
Thank you so much! Future plans are always top secret ;)
I grew up in the 60s, before the internet. I'm glad to have access to videos that expand ones education into areas never told of and towards careers or jobs never heard of. Thanks creators, YT and Google!
Thanks for sharing! Yes, YT is a life saver for many. My dad would watch it all day when confined to his bed in the years before he passed.
ALL BEAUTY.
Thank you for the video! I can finally start my report for our General Biology subject!
you're welcome, and glad it was helpful!
Great series.
Great informative documentary well explained
Thanks!
Loved this series! Can't wait for what's next! :)
More to come! Thanks!
Ah, finally the long awaited video about deep oceans
A fantastic conclusion to a fantastic series. I look forward to seeing what's next!
Glad you enjoy it! Yes, more excitement coming in 2022.
Thank you, truly well done
Glad you enjoyed it! Thanks for making it to the end of the series!
There's one more place you haven't covered. Inside of caves, where there's no light, there can be separate ecosystems that don't rely on plants since there's no photosynthesis there either.
Indeed. I was aware of this biome, but it's of an order of magnitude smaller than all the others (and pretty insignificant in regards to impact on humans), so did not include it. I may pick it up in a future special.
Amazing content.
Thank you!
Excellent video
NICE INFORMATIVE VIDEO.
FROM INDIA.
Merci beaucoup, fascinating.
De rien! Glad you liked it! Hope you enjoy the rest of the biomes series!
@@Geodiode I will, great content.
Amazing video
Thanks!
very helpful video 👍
Thanks!
Nice
Though the deep ocean is not the only ecosystem not based on plants. There is for example the Movile cave in Romania, which has been seperated from the outside world for ages and has a food chain independend of plants.
what a spectacular ending
Thank you! Made with ❤️...
Chemosynthetic bacteria could also be useful for deep space travel(better atmosphere processors)
Please continue your "Nation States of Earth" series. Make an episode about Bangladesh!
Thanks for the wonderful content. @Geodiode
i love the videos.....💗💗
I have suggestions for two biomes you have not covered:
The City biome and the Subterranean/Cave biomes.
Pretty sure they ended the series
Fantastic documentary thanks ❤ could be a bit longer……………..oops sorry it could for me 😊
Thanks - glad you like it Dave! I would have liked it to be longer too, but finding visual material that I have permission to use on this was very challenging (basically anyone with the wherewithal to take a camera down there wants money for the usage of it).
Great Video! I am wondering what biome san jose california is in though.
Thanks. It's almost certain Scrub, although drive for 10 minutes into the Coastal Range, and you're into Temperate Forest.
What else can be said? Yer a badass ;)
Umm, thanks? :)
Great Video. Can you make a video about Russia?
Thanks. It's your lucky day. RUSSIA will be released in about a month from now :)
Really enjoyed this series, I wonder what's coming next for the climate casebook. What plans do you have?
Thanks! My future plans are always top secret!
@@Geodiode flat earth truth would be a great topic
@@joshtheflatearthjedi222 May I ask what that means?
@matildalitsey143 I know it sounds crazy but I believe the earth is flat and stationary and the abyssal planes are one of the many proofs for that theory.
minute 3:05 - Volume/cubic meters = m3. Not m2. That's square. Also 1.300.000.000.000.000.000 m2 instead of 1.300.000.000 km2 isn't gonna make it easier to grasp and presented as square, not correct.
Let s discover another world.
thank you so much all country language translation ❤️❤️❤️❤️❤️subscribe now
Thank you. How were the subtitles in your language?
The abyssal plains are a great flat earth proof
