Saharan Dust Feeds Amazon’s Plants

The Sahara Desert is a near-uninterrupted brown band of sand and scrub across the northern third of Africa. The Amazon rain forest is a dense green mass of humid jungle that covers northeast South America. But after strong winds sweep across the Sahara, a tan cloud rises in the air, stretches between the continents, and ties together the desert and the jungle. It’s dust. And lots of it. For the first time, a NASA satellite has quantified in three dimensions how much dust makes this trans-Atlantic journey. Scientists have not only measured the volume of dust, they have also calculated how much phosphorus – remnant in Saharan sands from part of the desert’s past as a lake bed – gets carried across the ocean from one of the planet’s most desolate places to one of its most fertile.

Early morning in Venice
A view of the gondola stands near Rialto Bridge in Venice, just after sunrise, before they open for business.
One of the nice things about this hour is that you have chance to walk the streets without the usual tourist crowds, and calmly take in the sights and sounds undisturbed ;-).
