Shallow Seas - Continental Shelf, Coral, Plankton and Kelp - Biomes#11
HTML-код
- Опубликовано: 6 июн 2024
- Coral Reefs, seaweed, kelp and plankton. Just a handful of lifeforms that we find in waters where light can reach, where plankton can photosynthesise, and for a complex array of plants and animals to build upon that in a food chain. In this video, I explore the origins of Earth's seas, continental shelfs, and how life has developed within this biome.

In the formation of the Earth, a small fraction of the original material was ice. This eventually formed the oceans and seas as we know them today. Where light can penetrate the sea bottom, around the coastlines and within the continental shelfs, life can flourish.
🐠🦀🐙🦈
Seawater is about 3.5% minerals, with most of this being in the form of sodium chloride, and hence the water is saline. Plants and animals must evolve to cope with this salt in their internal membranes and tissues.
🐠🦀🐙🦈
The presence of light means photosynthesis, and this is the reason that shallow seas are so rich, with various types of plankton, microscopic plants and bacteria, being able use light to convert water and CO2 into organic matter. Other plankton feed upon these, and krill, jellyfish, crustaceans, molluscs, fish, sharks and whales feed in a complex food chain upon the rest.
🐠🦀🐙🦈
Sea flora, beyond the microscopic, consists of seaweed and kelp which a multicellular forms of algae. But the most notable "fixed" living organisms within the shallow seas are corals, which are in fact animals that have a photosynthetic symbiote within their cells. Corals grow through cloning and sexual reproduction to form coral reefs, as they excrete calcium carbonate at their base.
🐠🦀🐙🦈
Threats to the shallow seas ecosystem include the bleaching of coral reefs, overfishing, and marine plastic pollution.

What is your experience of the Shallow Seas? Tropical beaches? Coral scuba diving? Or with a wetsuit in the "temperate" latitudes?
I once went to vacation in Mexico in August, and the swimming & diving was like nothing else. I went to Cozumel and the water was beautiful and I picked a spot where the depth quickly dropped off to 50-100 ft. I don't know about swimming in higher latitudes but I don't think it would be as enjoyable as you can feel the temperature of water more strongly than air. I wouldn't want to live in the tropics, it's way too hot and I enjoy the feeling of cooler air. But being able to go south and swim in warm water in the tropics was one of my favorite experiences. Also I tried diving in cold water, the shock from the cold stunned me for a second, I'd say I like swimming in the tropics more.
i dont know how to swim so i never go far away from the beach
Living in the Caribbean I had the opportunity many times of enjoy beautiful beaches, with white sands and green-blue waters, very warm... and also I had the opportunity of see fishes, star fishes and corals diving, is a very amazing experience. This episode shows very well the beauty and the diversity behind the waters! 🧜♂️👏👏👏
Living/working on cruise ships for many years I've been fortunate enough to snorkle the Great Barrier Reef in Australia and dove in a wetsuit swimming the kelp forests of coastal Alaska. Magical experiences and your video brought that back!
I live in Antigua (an island in the Caribbean). Here, we have 365 beaches, but surprisingly, most of the locals can’t swim. It seems like they didn’t care to learn as the water is shallow.
Another excellent addition to our lessons. Having grown up in South Florida where beaches, snorkeling, and glass-bottom boat tours are just another part of every day life, it's a biome I'm very familiar with. And yet you still managed to teach me a few new things!
Nice to hear it Ashley!
❤🙏
Another master piece!!!!! I bow for the amount of hardwork to put in to make these videos.....
Thanks again!
Omg! This video went without advise down of the list... youtube failed... amazing video, so fully explained
Thank you for this episode😊
Another banger by Geodiode
Thanks!
I use your beautiful and informative videos in my college classes.
Thank you Greg! I made this video and will make the upcoming one just to round out the series, as I'm not really expert outside of climatology!
Congrats on 40K subscribers!!!!!!
Wow, fantastic! Super wonderful videos!!!
Thank you for the wonderful birthday present 😁🥳 I didn't expect you at all to touch on the seas and oceans so this was extremely educational and very fascinating. Amazing work
Happy birthday!! And thanks. This and the final episode are necessary to complete the series, since they are now being used extensively in schools.
@@Geodiode thank you, I really appreciate the birthday wish 😌❤️ it's amazing how far reaching and impactful your videos are
Excelentes vídeos, muito informativo.
That was awesome. Loved it this year, just like last. 💖 See you again next year, bro.
Thanks so much
I really enjoyed watching your upload!! Keep up the excellent work! I'm looking
forward to another awesome video!! Take care and stay in touch!! 🌻🌞🌻
Thank you! You too! Next video coming in just over a week... :)
Wow instantly subscribed. Wish I found out this channel sooner
Thanks for subbing - better late than never, and I'm glad you found it!
Great video, bro.
Glad you enjoyed, thanks!
Lovely video I enjoy a lot. There was damage to local sea food and reef by pollutants and illegal activity in the Taiwan area but preservation efforts are doing well to keep them in good shape.
Thanks...
Which must be frustrating for the Taiwanese - having to clean up the garbage of their neighbours!
Amazing nature, I love it❤❤❤
Thanks for stopping by
Amo el contenido de este canal, los videos son interesantes, educativos y una verdadera obra de arte.
Creo que en este mund globalizado tenemos la oportunidad de informarnos y compartir información con muchas personas, y cuidar nuestros ecosistemas marinos y mejorar nuestros hábitos alimenticios para tratar de no impactar negativamente el ambuente.
Tengo que compartir este hermodo video!!🥰🥰🥰
Muchas gracias!
This presentation is amazing. It is very concise, yet extremely informative and I was able to take notes very easily while watching and learning! Thank you!
Glad you found it useful! Thanks!
Another masterpiece
Thank you Alperen! It'll do :)
@@Geodiode Cake video about lake and river systems?
Hi ☺Geodiode! Nice video💙☺!where i live just have river and lakes; but this seas are so wonderful;
Thanks Elizabeth! I may do a "special" video on rivers and lakes in the future, although I kind of covered Riparian systems in my Wetlands video.
Grt video...
Nice
What a quality of video 📹
So lovely 😍 👌 👍 🥰
Many many thanks!
As a geography and astronomy learner, I really fall in love with your channel. Keep it up for your amazing videos. Who else likes ge🌍graphy ? 🌐🗺
Thanks a ton! Glad you found me!
❤️
Interestingly the continental shelf exists because of the last ice age, the lower water level eroded the coast to a certain extent and they have yet to conform to the current sea level.
Do videos on countries and their climate.
Go with India next. Focus more on western ghats , Andaman and nicobar islands and himalayas.
👍👍👍💕💕💕
I was hoping it would be longer.
I live in the Philippines and was shocked that they are such a massive marine polluter.
Just a one-man band here. Even 10 minutes of video takes a huge amount of prep time.
Yes, it is not talked about (because it's politically incorrect), but those Asian countries are producing the lion's share of ocean plastic pollution.
@@Geodiode locally here in the Philippines where I live they are very strict on recycling and charging a premium on disposable materials. For instance, a glass 12 oz bottle of coke costs about 27 cents. A plastic 12 oz bottle or even a can costs closer.to $1. They refuse to pickup your garbage unless it's separated, and most barsngays enforce no burn laws for garbage. So most people just don't generate a whole lot of trash here.. I think it probably comes from the richer classes in larger cities like Metro Manila, Cebu, and Davao. People there are more cutoff from nature and they live in concrete world made for making money. So they probably don't think about waste and where it goes.
That's not to say litter isn't an issue and that it doesn't here where I am get into the sea. Most storm sewers are open and little kids throw candy wrappers and things into them and that does get washed into the rivers and since we aren't that far from the Philippine Sea here, it does flow out into that body of water, which as you said is just the Pacific. I really don't know.if a solution on an archipelago that isn't just a scaled up version of what we do locally here in the Bicol Region.
Today I am going fishing for the first time with my friend's son. They use very primitive fishing vessels here called Spider Boats. They are a monohull design, made of wood, with two large outriggers. It'll be the first time I've seen the reef between Mercedes and Canimog island and it'll be interesting to evaluate its health. Thank you for replying to my previous comment.
@@Geodiode thank you very much for your hard work! These videos are like meditation for me. They reduce stress and humble me.
You are amazing and I love that you share these videos with us. Thank you :)
Greetings from switzerland!
Can't wait for when bees are added to Earth in the next update, oh wait....
Bees? Bees? Actually, I love them - and have started growing flowering plants in my garden to help them out...
When is water invisible to the naked eye?
I just remembered a rather unique biome that's found on every continent whose conditions are key for preserving archeological evidence, yet, are never much studied as a whole because they are mostly discontiguous and also are unique sites nestled inside of bigger, more general biomes. I'm talking about Shallow Graves. ☠💀
Good one!
So banning plastic straws in US won’t save the ocean life? I am disapppointed 😜
Indeed, because it's all about how plastic waste is (mis-)managed. We've figured it out here in the West so that almost all of it doesn't make it into the ocean. It shouldn't be that hard, should it?
Plankton💀💀💀
Don’t western nations send their plastic waste to eastern countries for disposal? Eastern nations (especially China) do need to better manage their disposal of plastic waste, but it seems a bit dishonest to point the finger at the east when we are certainly somewhat responsible for the predicament.
You are correct. Some plastic waste does go from the developed world to China. I don't think this is the case with Indonesia however.
@11.13, isn't spore the agent of asexual reproduction?
It is sexual. Spores only differ from seeds in that they are just naked sperm as opposed to a package with goodies in them.
Sadly countries in Asia know what they’re doing … and just don’t care .. just like how they don’t care about animals in general
