A team of researchers have recently provided estimates of the amount of dust that makes the journey to the Amazon. Of the 182 million tons of dust that gets lofted out of Africa, some 27.7 million tons of that same dust then finds its way to the Amazon rainforest. The same team of researchers that made this discovery have also announced that the phosphorous within the Saharan dust fertilizes the rainforest. Some 22,000 tons of phosphorous are estimated to rain down to the Amazon, far from their Saharan origin. The researchers estimate that this influx of phosphorous makes up for the all the phosphorous lost to erosion. Our world is truly dynamic. Our fleet of Earth observing satellites have so much to teach us about our home.
Here is a fantastic video from NASA explaining these new discoveries:
