check out info on this site http://myfwc.com/research/redtide/information/general/
It seems Florida has k.brevis almost every year, so they seem to have studied it quite a bit.
If I read the info correctly, it seems that algae blooms are somewhat linked to the iron rich Saharan dust that blows into the gulf from May thru Sept. That dust feeds an algae called trichodesmium, which produces nitrogen, that then helps feed k.brevis. So, if true, it makes sense that Florida has more of a red tide problem since it is closer to Africa and thus gets more Saharan dust on a regular basis.
Now, I'm wondering if the strange orange-ish bloom I saw while at Bob Hall a few weeks ago was actually the trichodesmium [based on pictures at the the Fl. website, it might have been]. |

First....yes, that was a Trichodesmium bloom that you witnessed. Second...the African dust theory is interesting but hasn't gained too much support from the scientific community. The idea is that the iron rich sands feed one microorganism which creates a waste product that feeds the dreaded RT organism.

Thankfully, nothing!
I'll quote from the original post, by that really, really smart individual from way back in 2013:
Again, this is just a theory.......
[Man, it's been that long??????]
Care to weigh in on the odds for a bad Fall this year? I have my money on the 'Superfecta' of butterflys, upwelling, dust, and big spring rains. 
[Edited] - I'll even throw in the two suspected Trichodesmium blooms I've seen past the 3rd bar in the last couple of weeks... No water samples to prove it, but I have a fair eye for these things. And I would LOVE to have egg on my face and be proven wrong. I'll gladly eat my hat with a hearty helping of pink salt for flavor. |

Any relation to the huge nutrient dump coming from the Mississippi River to these upwellings and subsequently cycling those nutrients up in cold water cycles?
Maybe they way the system keeps the balance nutrient wise utilizing the algae to use up the excess nutrients GOM wide?
Marine ecosystems not my forte, not like terrestrial ecology but seems like a lot of coincidences. Thanks for the graphs CS |

| What triggers the bloom is if I plan a trip to the coast in the fall. Don't want a bloom, send me money to bribe me not to book my trip... |

All the triggers have been fired off [already].....
Large Spring Rains
Mid Summer Upwelling Events
Sarahan Dust Blowing into the Gulf
Sea Sawdust (Trichodesmium - that's precursor) Blooms already noted
...And don't forget Tyler's Butterfly Swarms
I'll quote from Rodney Dangerfield at a stripclub:
"Hey Darlin', Here's $5 bucks, TAKE A BREAK"!!!!!! |
