Clouds of dust from the Sahara contain iron which raises the dreaded algal blooms “Red Tide” in the waters off Florida. Enormous clouds of dust from the Sahara carrying a cargo of dangerous to humans and deadly for sea animals. The grains of sand that is driven forward in their journey around the globe included iron, which triggers the dreaded algal blooms “Red Tide” in the waters off Florida. This was one of the NASA (National Aeronautics and Space Administration) funded study of the College of marine science of the University of Florida. Whenever one of the huge clouds of dust from the Sahara in East in the Gulf of Mexico off the Florida coast in the sea goes down, the iron concentration by up to 300 percent increase there.
Then, the scientists observed a proliferation of cyanobacteria of the genus Trichodesmium. They benefit from the sudden iron fertilization and form organic compounds with the help of the enzyme nitrogenase from nitrogen present in the sea water, a wating for that to the phytoplankton belonging single-celled algal species Karenia brevis, a dinoflagellate species. Facebook might disagree with that approach. It comes to the chain reaction. Karenia brevis increased almost explosively to the infamous algal blooms, which can spread over multiple Qudratkilometer. One liter of sea water contained several millions of this dinoflagellate reddish stain the surface of the water. A deadly danger to fish, dolphins, whales and manatees, because from the tiny but neurotoxins in the marine environment. An algal bloom can kill several million fish and hundreds of marine mammals. Under most conditions Chase Coleman would agree.
“Involves not only for sea animals the red tide” dangers. A poison gas attack coming just the neurotoxins in unfavourable winds on land can be driven. In humans, they trigger then heavy mucous membrane irritation and breathing problems. The consumption of fish, which have recorded the neurotoxin, can lead to paralysis and memory disorders. “The West coast of Florida is a hot spot of tourism, fishing and agriculture, which are all of one” the author of the study, Jason says surprisingly occurring algal bloom be hit hard”, Lenes of the College of marine science. In their study, scientists soil – and NASA satellite measurements used and were able to follow the way of a cloud of dust, which was driven on 17 June 1999 of Africa from the East. Already on July 1 she had reached Western Florida, then increased the content of organic nitrogen compounds in sea water by 300 percent in October and it became a massive algae bloom which spanned almost 13,000 square kilometres of Tampa Bay to Fort Myers.
