- Maybe you already knew that deadly algal tides discolor ocean waves, deplete the water of oxygen, and release toxins that can kill a huge range of ocean critters, but did you know that the tiny organisms that cause red tides are also an extremely important part of our ecosystem? In this episode of #Untold, a new #TH-camLearning series from ACS, PBS, and TH-cam, we dive into the science behind this somewhat terrifying, sometimes glowing phenomenon.

Harmful algal blooms are popping up in new areas, partly because of changes in ocean temperatures--just one effect of climate change.
were can I get G.M.Algae for oil production ?
So is red tide lake O we have to help the climate scientists understand how this issue has come about.
Its because of fertilizer
😂

Im blown away by the quality of the video and the comparatively low view count.
This is a good video!
Most people just see information on tik tok and take that for what it is. Instead of looking it up and learning as much as they can on the subject. They just don’t even bother lmao. But their loss I guess
@@dhgzebraa261yea my dad use tik tok as a news source
Kinda just a typical youtube video with bunch of stock video bro. There's a thousand channels just like this lurking about. Science fact channels are a dime a dozen.
Likewise sir likewise
As a Gulf Coast resident, I appreciate this information. It's been a very bad summer for swimming in the Gulf! I now want a t-shirt with the molecular diagram of brevetoxin overlaid by the international "no" symbol.
I own and operate a watersports business in South Florida and this is the best video I've seen online explaining what we are experiencing on our coast and local waterways.
Companies dumped chemicals into the bay... its not all natural. its because they polluted
Then you should be hounding your elected officials to clamp down on the excess fertilizers that trigger these algal blooms.
Over a decade ago the Florida government was supposed to start buying back sugar cane fields and letting them return to natural wetlands (without fertilizer) but the politicians in charge of Florida have not done this, to protect their wealthy donors in the sugar cane industry.
Algal blooms are natural, but blooms in March (lie we are having this year) are man induced and are preventable.
Great job ! Really interesting, good for curious people, thank you !
I'm loving these series
Why thank you.
Wonderful video, informative and interesting :) It is nice to learn how those algae glow in the night.
I have a shore house on the NJ shore. One year the tide was really high due to stormy weather and the moon cycle. It caused the water level to rise over the shoreline and everything flooded. In the following days/week we had an algae bloom that wasn’t really visible to the eyes. But at night if you disturbed the water, it would light up bright! I didn’t understand it entirely at the time, but I do now thanks to you. I appreciate that.
Wish I could have shown you all how cool our boat looked at night. The entire wake (the bubbly streak of disturbed water behind us) was glowing green like a glow stick. It looked like we were a comet. :0
I am trying very hard to learn, but it's hard when all you hear is ”dino flatulence”

Thank You for this, I was just fishing in Santa Cruz California on my kayak and wanted to understand red tides as it was a red tide that I was out on. Fish don’t bite and fish were mostly gone but your video made it very enjoyable and easy to understand. Thank You!
Thanks🙏🌹
OK You got a new subscriber, great voice, pronunciation diction and great info.
Wait, the fact that seaweed and kelp are algae _isn't_ well-known in English-speaking countries? In Spanish, the term for seaweed _is_ algae, to the point where I was actually surprised when I first learned that algae referred to a whole group of organisms, not just seaweed. So basically, the opposite mindblow.
yeah and in french any green thing in the water = algae, even aquatic plants
English was my first language and I definitely did not realize they were a type of algae before this video. Pretty interesting how language can impact our thinking so much. I suspect this falls under the Sapir-Whorf hypothesis.
This was beautifully done. Thank you!
Nice explanation 🥰
Loves from India🇮🇳😘
First time seeing this channel. What an amazing video, and looking forward to more.
Very informative and entertaining! Hopefully it catches everyone's attention
Really good video. Thank you. Best wishes..
Excellent explanations incorporating many chemical concepts with great graphics. Thank you and God bless you.
Very well done video. Living on the Florida water I am suffering this red tide badly. Thanks for the great information ;)
Really enjoyed this one. Keep up the good work.
This was so damn good. So much good stuff delivered perfectly. Wish it was so much longer, hahaha.
Very high quality video and excellent presentation. Thank you!
Well Explained. Kudos Doc!
Thank you for this video! I just went to the beach and there was red tide so I wanted to understand why that was.
can you also share information on the green/ black algae tides on the western coast of Florida and the effects of breathing in their toxins ? such as the link to dementia and alzheimers
Dont look now but there is a spider on your screen ...Great series
Did I miss the party where she mentions that it is made much worse by the fertilizers we flush into the ocean. Look at that beautiful lawn
Thanks for the info!
What a boatload of information! Wow! 👏👏
Excellent work.
Perfect presentation!
Awesome video! Very well done. It would be helpful if the CC were edited at 3:15 to read, "ichthyotoxin" rather than "exotoxin".
That photosynthesis part was a plus and I only knew now how bioluminescene work.
Its an awesome series!
I wish I had played more attention in science in high school. I ended up dropping out which I regret but due to some family issues I moved out and started working at 16. Now that im in my 50s it's subjects like this that interest me very much. If I had a teacher that was as good at explaining things as she was I definitely would of paid more attention! She was very articulate and kept it very interesting explaining everything so well even this high school drop out understood it!
Great video!
Nature is so magical 😍🥺
Ģreat explanation and varied opinions on fringe relationships ......subbed in a heartbeat 🤗
Thank you for your videos 🙂
Thank you very much for this video: i get on her accidently and that’s very interesting, well explained and nicely showed
And this speaker is absolutely cute
Keep doing, that’s awesome👍🏻
I almost drowned as a kid in "red tide" not knowing the algae were poisonous and I swallowed a lot of water, I remember having diarrhea right there on the beach and feeling horrible
Very interesting! Subbed.
This series has been great! I have a question about acids and bases, though. Can things become acidic or basic because of ions besides H and OH? I don’t know if it’s something special about those ions, or if it’s just because they’re so much more common because of their size and because of water that we don’t have to worry about other ones, or if there’s a whole lot more about how it works that I don’t know yet.
@Ryan M water and h+,oh- ions are more common than other ions,they influence the acidity or basicity. Other ions effect is negligible because they arent common
Check out Lewis acids and bases... it'll blow your mind.
This is so cool and interesting I love this video and it will help me for my silence class
Nobody: the spider on her computer chilling🕷
awesome, awesome stuff!
So that's why Florida is so crazy!!!
What makes cali so messed up then?
Hope this would last longer.
Ok but you still havent explained why the fish killing algae is necessary in the food chain
I have never thought how 'sophisticated' ways there are the sea being that dangerous😗😳
Thnx i think it understand atoms a little more now!😅
Don't forget my favorite green allergy
It's awesome but scary, there should be a way to content sargassum's bloom because many fish is dying and people is getting sick from it. It doesn't sounds well 😕 I hope the government and scientist could work together to solve this worrying situation in Florida... So, the video was very informative, I like it. I was watching news about sargassum's bloom in Florida and I was thinking oh, it's very dangerous that people keep going to beaches because this seaweed is toxic and can cause throat irritation and red eyes, the video says that they can pollut shellfish 4:20 government should forbid to eat them, to avoid that people get sick.
This is better than my biology teacher
They are too busy trying pushing progressive politics on you
Well guess I'm not eating shellfish again
Every time some industry dumps waste into the ocean they call it red tide dead fish disaster red tide how convenient
Cause of the spill at piney point in Florida let’s shut em down
I saw a television movie
Los Angeles 2017 AD about pandemic toxic algae blooms which killed off the human species. The survivors had to live underground and were facing extinction. Philip Wylie wrote the screenplay and the science fiction novel. Could toxic algae blooms get that bad and do that much? I'd like to know your point of view and reaction. Maybe you could do a program about the television movie and novel.
Thanks, Phillip Jones
Oh no...spider on the screen😰😰
Is this something to worry about this summer ?
I would grow all different colored algae in some of my aquarium s... My favorite was purple..
I think will not live within 1.62 kilometers of the ocean. I have never understood the charm of it.
Really great video!
Just a tiny comment: at 10:26 you refer to OH-anions as hydroxyl-ions. According to IUPAC-convention, the OH-anion should be to referred to as hydroxide. The "-yl"- suffix should be used for the OH-radical.
Anybody know where 4:59 is at?
I live on the Gulf Coast and red tides are as familiar as rain.
Can removal of some red algae? To helps reduce the amount of die off?
5:05, where is this?
I therefore conclude that, there's always skittles at the end of the rainbow.
One time I saw a blue tide, but later found out it was just the ocean color.
Dinoflagellates are algaes I never knew thankd
bio-weapon expert here......decayed fish on your new beach house. No wonder this video is hidden with complicated chemistry and a smile.
7:05 - Uh, I think that stock footage had its rainbow added in post. Notice how the red is on the inside?
@@faenethlorhalien Thanks, that one always gets me.
red tide is a micro-organism, sometimes things like clams or muscles can filter the organism into itself. Since it doesn't die, the red tide cab remain in the flesh of the filter feeder, for a long time after its death.
The 3rd vial of wrath in revelation will be global.
i have a friend that is not allowed to watch this video. as soon as you started describing the symptoms, she'd start feeling them...
Hm?
@@user-xr4jy5vv4f Synesthesia
@@forrestl5597 ah
real estate agents never mention this.......on the Gulf Coast of "Flawda"?
I know people in Florida who live on Del Ray beach and they are chronically sick with some type of respiratory illness. There dog died and there cat is sick and dying both with some type of respiratory infection. It’s obvious to me what the cause of there are sickness is it’s at it’s worse when the red tide is at it’s worse but they are poor not very smart. They don’t have the money or enough commen sense to leave.
Wow AHS in a story on this?
1:16 how can algae be part of the plant kingdom and not be a plant??
Thank piney point reservoir for the views in 2021...so sad
Thanks for the great video! Small riddle: How many clues can you find that the rainbow at 7:05 is fake?:)
At least it's inside out. It might be a secondary rainbow, but it's way too bright for it. Plus the area where it appears does not seem to contain many water droplets. Anything that I missed?
@@user-user.user-user Well spotted:) One more thing is the lighting direction and the direction of the rainbow. At least if it is supposed to be illuminated by the sun, the rainbow should be on the opposite direction of the sun, so if you're looking at a rainbow the sun should be behind you.
@@feudiable You're totally right! How could I miss that! Arghh! ;-)
Can somebody's tells me what is at 7:46. It looks cool.
Pretty sure that’s yellow stone national park
Don't forget about toxic runoff that's certainly not helping thing's
She reminds me of that cute receptionist from the office
san you fere mach dide😇😇😇😇🤔🤔🤔🤔🔥
there is a spider didnt you see
This is why I don’t eat seafood yall trippppppin
It sounds like a yeast infection
Who’s here after leaving Pass-a-Grill beach? Lol
A year later it aged well after what's happening in florida.
This was bad 20y ago
Isnt this where shrimp n lobster n flamingos get their colour from.. there colour is from the algae
About chemical
Dino Flatulence?
Machi kharvad dayala deu. 😂😂😂 same weapon.
Who heard of the 400 pound grouper dead by of red tide on the beach
Is this a first date? lol
Damn preload ads
Thanks 🙏 to your TH-cam channel 🔥🔥 I’m done ✅ complaining 😭 and have decided 🤸🏽♂️ to start a TH-cam channel
Beautiful- the wildlife
Deadly - greedy humans
I like the ideas, but i feel the videos are rather jumbled of vague information and extremely detailed information orded by time mentioned and not relavence.
