The thought of a Super Bloom off the coast of Florida seems singularly unpleasant:
Title: "What Is a Brown Tide? Scientists Fear Florida Red Tide Could Merge with new Outbreak to Create Super Bloom"
https://www.newsweek.com/what-brown-tide-outbreak-red-1090429Extract: "The annual outbreak of algae called a brown tide has begun off the coast of western Florida and scientists are hoping it doesn’t meet up with the red tide that they’re already facing.
The brown tide near Florida is made of Trichodesmium, a cyanobacterium, or blue-green algae. The bloom occurs every year in the Gulf of Mexico and has been known to extend so far that’s it’s visible from space.
Records of the brown tide date back to the 1700s, according to the Florida Fish and Wildlife Conservation Commission. Captain James Cook of the British Royal Navy first wrote about large, brown blooms in the water that looked like sandbars.
Since the algae can form colonies that are big enough to be seen by the naked eye, sailors sometimes refer to it as “sea sawdust”. The tide is brown when it’s healthy, but when it begins to decay it turns green, then pink or red, then white. The toxins also smell sweet when they are decaying, like freshly cut hay."
