Patagonian dust over the Atlantic Ocean
On Jan. 24, 2010, a thick cloud of dust was spotted swirling off southern Argentina into the Atlantic Ocean. Here we see it imaged by MODIC onboard the Terra satellite. Air turbulence is the reason the plume rippled across the ocean, inciting a phytoplankton bloom feeding off the iron in the dust. Later that day, the Aqua satellite photographed the same area, showing the dust concentrated over the Atlantic.
