Saharan dust clouds brought particles of dust with iron to the waters off Florida's west coast, creating huge blooms [deposits] of toxic red algae.The Saharan dust entered the upper atmosphere and circled the globe.
When the dust reached the Florida's west coast, it increased surface water iron concentrations there by 300%, which then increased by tenfold the count of bacteria in the water.These bacteria caused a "red tide" which can kill some forms of marine life and causes serious skin and respiratory problems in humans.By using satellites to monitor Saharan dust clouds and bacteria blooms, scientists will one day be able to forecast red tides in areas that will be affected.
