Over time, atmospheric chemical reactions can make iron in dust from the Sahara easier for organisms to take in, helping to create biodiversity hot spots.

Scientists from the US measured the relative amounts of ‘bioreactive’ iron in four sediment cores from the bottom of the Atlantic. They showed for the first time that the further dust is blown from ...

As dust-laden iron travels farther from the Sahara, atmospheric reactions make it increasingly accessible to support life.

This indicates the Saharan dust is heavier in bioreactive dust that gets used up by aquatic organisms before reaching the bottom of the ocean. At the same time, however, the remaining dust that ...

and southwesterly winds in the winter and spring that dumped the Saharan dust onto the Alps, causing a warming effect on the ice. Switzerland is home to the most glaciers of any country in Europe ...

It’s “detection of an unprecedented diversity of microbial taxa at heights [far above the planetary boundary layer],” he adds ... Research has linked Saharan dust storms, for instance ...

Oftentimes, clouds can make for more colorful sunsets. Adding a thin layer of smoke can add to the view. Saharan dust acts in a very similar fashion. Currently, dozens of wildfires are burning ...
