The Terrifying (but Awesome) Science Behind Red Tides

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 #KZbinLearning series from ACS, PBS, and KZbin, 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.

[@tylerzammuto8423]

Companies dumped chemicals into the bay... its not all natural. its because they polluted

[@mafarmerga]

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.

[@Adventurewithnhia]

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!

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.

[@McPhysX]

yeah and in french any green thing in the water = algae, even aquatic plants

[@IanGrams]

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.

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!

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.

[@immortal_coil]

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.

[@guillermomendoza1096]

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.

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?

[@feudiable]

@@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.

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.

[@ryanm9513]

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.

[@Leo911-v1t]

@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

[@ACSReactions]

Check out Lewis acids and bases... it'll blow your mind.

[@Michael_MW]

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

There's no science behind it. Bible said the waters will be turned red like blood. It's just one of many signs that coming of Jesus is near. Repent and put your trust in Jesus who died for your sins 2000 years ago on that cross, taking the punishment you deserved upon himself, so that you can be freely justified if you repent and bealive in Jesus and that he died for you on that cross. Bealive in Lord Jesus Son of God and you will be saved! Amen
