No warning. Just a beach full of people who start coughing at the same time, grab their towels, and leave. That's red tide, and it feels completely random until you know what's actually happening in the water. Karenia brevis, the algae behind it, produces a toxin called brevetoxin that rides the wind and waves into the air along the shoreline, which is why people can start coughing with no visible sign anything's wrong. The 2017 to 2019 Southwest and Southeast Florida bloom cost the region an estimated $2.7 billion, mostly in tourism losses, and it wasn't a freak event. Follow the water back far enough and it traces to nitrogen and phosphorus flowing out of the Kissimmee River basin, through Lake Okeechobee, and down the Caloosahatchee River into the Gulf, fueling the same algae that's always been there into a much bigger, longer bloom. Here's the turn: this is trackable. Mote Marine Laboratory's Beach Conditions Reporting System lets anyone on the Gulf Coast check named beaches for red tide conditions before they ever leave the house, the same way you'd check a weather forecast. This episode also connects back to the nutrient-pollution mechanism from the "nature's kidneys" episode with Adam Langley, and lands on one thing you can actually do this season. Takeaways: Red tide is caused by Karenia brevis, an algae that produces brevetoxin, a toxin that becomes airborne in sea spray and can cause coughing and respiratory irritation, worse for people with asthma but capable of affecting anyone near the water. The 2017\u20132019 Southwest and Southeast Florida red tide bloom cost the region an estimated $2.7 billion, mostly in tourism-dependent business losses. Red tide blooms are naturally occurring, but excess nitrogen and phosphorus flowing from the Kissimmee Basin through Lake Okeechobee and down the Caloosahatchee River make them bigger, longer, and more frequent. A legally mandated program has cut phosphorus leaving Everglades-area farmland by roughly 55 percent long-term, against a 25 percent legal minimum, but the broader system still isn't meeting the water quality standard the Gulf and estuaries need. Mote Marine Laboratory's free Beach Conditions Reporting System lets Gulf Coast beachgoers check red tide conditions beach by beach before they go.
