@Ben Ng true. Maybe some way to physically prevent the trawling. I wonder if it would be possible/practical to erect some sort of anti-trawling structures. They could be erected around reefs particularly vulnerable to trawling and would catch or cut any nets that would be try to break the reef. It wouldn't be a perfect or scale-able solution, but I wonder if it would be possible
The problem with stopping it, is that that would severely damage fishing economies, and the fishermen who work these nets would be put out of a job. Along with a host of other problems that may be even more detrimental to the ecosystem and other things. Before you go trying to get things banned, you must first see the whole picture. There is so much more to these types of problems than people think, and all sides must be addressed. A better way to fix the problem may be regulating and limiting where, when and how ships can trawl.
You failed to mention the problem with dams on rivers. They prevent sediments from reaching the ocean. The sediments would normally neutralize carbonic acid, keeping the Ph of the oceans more stable.

@@pugdad2555 the deadzone isn’t cause of the sediments, it’s because of the phosphorus and nitrogen minerals from the massive amounts of fertilizer used on the farms around the Mississippi, which then feeds algae, and when the algae die they sink to the bottom and bacteria eat them and use up oxygen in the process of eating, and that’s the process of environmental hypoxia

Small correction: The section on aragonite caught my ear as I did a project on it during my masters program in materials engineering. Aragonite isn't a dissolved form of calcium carbonate, it's a morphology of solid calcium carbonate that is precipitated out of solution via biopolymer scaffolding (at least in marine monovalves). I believe the dissolved material is just calcium ions and carbonite ions, it doesn't become aragonite until it solidifies. Also at 9:10 there is a typo where it's misspelled as "argonite" Hope this helps!

Shallow corals are actually fairly recent in evolutionary terms most corals are deep corals because they are the reservoir population from which shallow reefs evolve from. In fact during the Mesozoic the main reef builders weren't corals at all but rather a group of organisms known as Rudist clams which like shallow corals appear to have relied on photosynthetic algal symbiotes based on their strongly diurnal growth patterns (which also allowed us to calculate the length of a day back in the cretaceous ~23 hours 30 min) There were coral reef builders back in the Paleozoic but they all died out in the great dying along with most other reef builders like crinoids and brachiopods. Really shallow reefs and ecosystems in general appear to be both very productive but also very fragile pretty much every major or minor mass extinction wipes out shallow water species only for deep water species to move in to fill the vacancies.
@@Dragrath1 Thanks for the good info. I hope deep water corals survive in the future. I had read about the 23 hr 30 min day 70 mya but did not know clams were the source of the data.

1. snazzy earrings! 2. is this how corals would recolonize after a mass extinction event, drifting in from the deep ocean and adapting? and how long have corals been on earth?
What I find most interesting is how every nature channel frames the conservation like we all just have to come together, the universal human experience to save earth. Never once have I heard anyone highlight Indigenous land defenders or communism as the actual solution to a crisis caused by markets and for-profit economic systems. We can't all come together. We can't rely on "science" like science is some abstract good that has no class position. We need a planned economy based on science!
I love that you brought up indigenous people!! There are studies that analyze the biodiversity in the patches of forest they tended to, and the productivity of those patches are much higher than the land around them. Current nature conservation stemmed from Americans seeing landscapes after pushing out the natives that once tended to it, and thought that since no one lived there it was better for it, but today we are realizing that the maintenance of the forests were beneficial to both the forest and the people. Examples range from native tribes from the American eastern seaboard to native tribes in California that controlled wildfires for the benefit of the forest.
I worked in a lab and we were testing pulsing Coral It's a soft Coral. What we did is we would put a certain amount of sunscreen on to the back of our hands after washing our hands of course. We would wait a set amount of time and then stick our hands into the water like you would if you were putting on sunscreen and then going into the ocean. We had our hand at different lengths away from the coral both vertically and horizontally and after different periods of time we would take count of how many times the coral pulsed . What sections were affected by the coral first etcetera Chemical sunscreens do negatively affect the coral. They make it Heavily slow pulsing Which is what allows it to seed And slow its reproductive time Etc . Chemical sunscreens are safer than the physical sunscreens however. As the physical sunscreens actually have a little metal Flex that are small enough to kind of embed into the top layer of our skin but not small enough to actually work its way deep or even near to our blood system. And wraps it does because they have very thin skin and it does still take a. Of time but that's beside the point. The issue is many people see you the physical sunscreens are safer for us and less chemicals. However it is more dangerous to the Aquatic Life if you're going swimming . Also chemical sunscreens start working after a few minutes or as the physical sunscreen if you have only put it on one day and then jump into the water it can essentially be rubbed off and washed off. It takes days of repeated use for it to actually build up a little bit into the skin to offer solid protection no matter What you're physically doing. There were studies done with pigs using physical sunscreens with zinc and titanium . We would put the sunscreen on the pigs about 5 times a day For 30 days and then we would test the pigskin . After about seven days you could actually go two days and still have a decent amount of sun protection. However those was depression may want to take vitamin D supplement Or with winter depression but generally 15 minutes of sunlight on your hands and face is enough for your body. Anyway just keep that in mind when putting on sunscreen and going to the beach. Maybe we shouldn't be putting on sunscreen and going to natural lakes and such. Maybe we shouldn't spend so much time at natural lakes and oceans where we need to wear sunscreen. I know it's common for everybody but it is destroying our environment and nobody ever talks about this. Every time I bring it up everyone acts like I'm just some crazy naturalist that wants everybody to get skin cancer. No I want people to realize the effect they have and maybe we can limit the way we are poisoning our planet with Our own footsteps . There is no way you can live a life without affecting the world around you puts try to make it in a good conscious way not lose these reefs that have taken millions of years to form and evolve and that we admire so much
There is another contributor to acidification. The plastics industry makes polymers from monomers using sulfuric acid to link the monomers together. When the acid is no more useful for business, this "spent" sulfuric acid is dumped in the ocean. Please consider a SciShow segment on the good, bad, and ugly side of plastic manufacturing.

We dont know that its due to humn activity, randall carlson could explain how research into past co2 pevels don't directly correlate to warming temps, amd that much more is at play than just our greenhouse gases. We should be going into an ice age right about now, but aren't, and it certainly seems that it corelates to levels of greenhouse gases, however there are a few times in history where warming climates have been during low co2 levels and vice versa, so it's not as simple as cutting emissions. We're at over 400 ppm now, but the planet has seen over 5000 ppm and still saw plenty of life and coral reef action. So perhaps in pointing the finger, you are diverting from the issue. Who knows? No one actually, but better to be open minded when facing uncertainty, than to feel certain about something, which we aren't certain about. I personally think the ozone hole is the main culprit, that alongside with concentrations of greenhouse and toxic gases.
Things to note: 1.A) while there is no sunlight in the deep, there are few (single digits here) studies that have looked at presence of algae/ eukaryotes in deep sea corals so their presence is unknown however photosynthesis is likely not possible at this depth. 1.B) We don’t know if deep sea corals rely on algae, what is said here is misleading. Many algae (symbiodinium) are mixotrophic dinoflagellates which can photosynthesize but also live heterotrophically (eating bacteria for energy) thus they could survive at this depth, they just wouldn’t be relying on sunlight for their energy 2.) along side what was mentioned, Bamboo/octo corals have more calcium carbonate in their skeleton has more magnesium than stonier coral regardless of depth. This makes their skeleton stronger and more resilient to acidic waters. 3.) octocorals have been noted to be opportunistic feeders relying on filtering for food or using algae although many have been documented having preferences. This preference has been shown to change seasonally too. 4.) depending on the pacific/Atlantic water below 200m is not the same. The Pacific is much colder than the Atlantic 5.) unsurprisingly, I have isolated multiple bacteria from deep sea coral mucus capable of hydrocarbon degradation. However, no one has been able to prove why this is yet… only few papers exist on this. 5.B) while researchers have suggested this, it has yet to be proven as few studies exist regarding cultures bacteria from deep sea corals. 6.) test of the information is spot on :) Keep science-ing everyone!

I love that you brought up indigenous people!! There are studies that analyze the biodiversity in the patches of forest they tended to, and the productivity of those patches are much higher than the land around them. Current nature conservation stemmed from Americans seeing landscapes after pushing out the natives that once tended to it, and thought that since no one lived there it was better for it, but today we are realizing that the maintenance of the forests were beneficial to both the forest and the people. Examples range from native tribes from the American eastern seaboard to native tribes in California that controlled wildfires for the benefit of the forest.
Speaking of reefs, a video on the formation of non-coral reefs would be really interesting, such as the Capitan Reef formation
Deep ocean stuff is amazing
Pretty dress and earrings.
Bring her back for more videos please.
I like this host, she should get more episodes.
New host.
I approve.
She seems less confident but that comes with time and practice.
Sending much love
That’s great I did assume coral in deep water was only sparse and around geothermal structures.
Q: So plant hairs, what are they for? How similar to animal hairs are they, and do they keep a plant warm? And are thorns hairs or leaves?
If you’re talking about cactus plants with hairs in them i think those hairs are made of chitin

I worked in a lab and we were testing pulsing Coral It's a soft Coral. What we did is we would put a certain amount of sunscreen on to the back of our hands after washing our hands of course. We would wait a set amount of time and then stick our hands into the water like you would if you were putting on sunscreen and then going into the ocean. We had our hand at different lengths away from the coral both vertically and horizontally and after different periods of time we would take count of how many times the coral pulsed . What sections were affected by the coral first etcetera Chemical sunscreens do negatively affect the coral. They make it Heavily slow pulsing Which is what allows it to seed And slow its reproductive time Etc . Chemical sunscreens are safer than the physical sunscreens however. As the physical sunscreens actually have a little metal Flex that are small enough to kind of embed into the top layer of our skin but not small enough to actually work its way deep or even near to our blood system. And wraps it does because they have very thin skin and it does still take a. Of time but that's beside the point. The issue is many people see you the physical sunscreens are safer for us and less chemicals. However it is more dangerous to the Aquatic Life if you're going swimming . Also chemical sunscreens start working after a few minutes or as the physical sunscreen if you have only put it on one day and then jump into the water it can essentially be rubbed off and washed off. It takes days of repeated use for it to actually build up a little bit into the skin to offer solid protection no matter What you're physically doing. There were studies done with pigs using physical sunscreens with zinc and titanium . We would put the sunscreen on the pigs about 5 times a day For 30 days and then we would test the pigskin . After about seven days you could actually go two days and still have a decent amount of sun protection. However those was depression may want to take vitamin D supplement Or with winter depression but generally 15 minutes of sunlight on your hands and face is enough for your body. Anyway just keep that in mind when putting on sunscreen and going to the beach. Maybe we shouldn't be putting on sunscreen and going to natural lakes and such. Maybe we shouldn't spend so much time at natural lakes and oceans where we need to wear sunscreen. I know it's common for everybody but it is destroying our environment and nobody ever talks about this. Every time I bring it up everyone acts like I'm just some crazy naturalist that wants everybody to get skin cancer. No I want people to realize the effect they have and maybe we can limit the way we are poisoning our planet with Our own footsteps . There is no way you can live a life without affecting the world around you puts try to make it in a good conscious way not lose these reefs that have taken millions of years to form and evolve and that we admire so much
Hauntingly beautiful
Good Job!
3:16 ... What is that, what's tangled up in that coral?
Edit: Thanks found it. 5:10 Shows it is a star"fish".
There is another contributor to acidification. The plastics industry makes polymers from monomers using sulfuric acid to link the monomers together. When the acid is no more useful for business, this "spent" sulfuric acid is dumped in the ocean. Please consider a SciShow segment on the good, bad, and ugly side of plastic manufacturing.
Fascinating! 🖖
Enjoying the new host, her pronunciation is very good!
You never know what presenter you're going to get: scruffy dudebro on a beer run, or glamorous lady headed to a movie premier. Ya watches yer scishow and ya takes yer chances.
Thanks got the coral update!
The ocean is a amazing place.
Great video. Thanks for sharing.
rose is my favourite host
1:00 that crab is the stuff of nightmares
Nice to hear Antarctica pronounced properly, and a fascinating video to boot👌🏻
We dont know that its due to humn activity, randall carlson could explain how research into past co2 pevels don't directly correlate to warming temps, amd that much more is at play than just our greenhouse gases. We should be going into an ice age right about now, but aren't, and it certainly seems that it corelates to levels of greenhouse gases, however there are a few times in history where warming climates have been during low co2 levels and vice versa, so it's not as simple as cutting emissions. We're at over 400 ppm now, but the planet has seen over 5000 ppm and still saw plenty of life and coral reef action. So perhaps in pointing the finger, you are diverting from the issue. Who knows? No one actually, but better to be open minded when facing uncertainty, than to feel certain about something, which we aren't certain about.
I personally think the ozone hole is the main culprit, that alongside with concentrations of greenhouse and toxic gases.
"No matter where you are in the world"
Yeah, im in the upper midwest...
The entire midwest was once under a shallow sea. So there is definitely coral beneath you. Almost certainly dead and fossilized, but there nonetheless
@@angelitabecerra i thought start digging!:-) 🖖
Your dress is stunning.
Again, the new host is so great🙌🏽 Very good job young lady👌🏽
What is a mile? How far is 85 miles in international units?
And the craziest part is that they are highly intelligent omnipotent aliens who want to understand humanity and take them to paradise.
How do ancient people even harvest deep-sea corals?
Things to note: 1.A) while there is no sunlight in the deep, there are few (single digits here) studies that have looked at presence of algae/ eukaryotes in deep sea corals so their presence is unknown however photosynthesis is likely not possible at this depth.
1.B) We don’t know if deep sea corals rely on algae, what is said here is misleading. Many algae (symbiodinium) are mixotrophic dinoflagellates which can photosynthesize but also live heterotrophically (eating bacteria for energy) thus they could survive at this depth, they just wouldn’t be relying on sunlight for their energy
2.) along side what was mentioned, Bamboo/octo corals have more calcium carbonate in their skeleton has more magnesium than stonier coral regardless of depth. This makes their skeleton stronger and more resilient to acidic waters.
3.) octocorals have been noted to be opportunistic feeders relying on filtering for food or using algae although many have been documented having preferences. This preference has been shown to change seasonally too.
4.) depending on the pacific/Atlantic water below 200m is not the same. The Pacific is much colder than the Atlantic
5.) unsurprisingly, I have isolated multiple bacteria from deep sea coral mucus capable of hydrocarbon degradation. However, no one has been able to prove why this is yet… only few papers exist on this.
5.B) while researchers have suggested this, it has yet to be proven as few studies exist regarding cultures bacteria from deep sea corals.
6.) test of the information is spot on :)
Keep science-ing everyone! Sincerely, a marine microbiologist researching deep-sea corals
Also if note, when I say “deep sea” I mean well below the photic zone, so >500m.
TRAWLING is HORRIFICly destructive
Rick Grimes:. "We have to find coral!"
12,000 years ago, during glacial age, the seas were 400 ft lower. What happened when all the water appeared?
Explain--please!
We named my daughter Coralanne for the Coral species and her Mothers.
Love your face! Best of luck.
Ok but the coral reef pic at 00:58... wtf was THAT!? That thing to the side! Was that a crab!? It looks like it eats pets!
The monster under the bed, the granddaddy of all spiders, CRAB
I learned from the Magic School Bus...the connection between algae and coral + bleaching...in shallow water
its sad that the huge corporations responsible for all the pollution will not do anything until its wayyy too late because it all just comes down to money
I think the new host is growing on me.
Coral reefs are the jungles of the oceans.
