Is a great iron fertilization experiment already underway?

ST. PETERSBURG, FL – It’s no secret that massive dust storms in the Saharan Desert occasionally shroud the North Atlantic Ocean with iron, but it turns out these natural blankets aren’t the only things to sneeze at. Iron released by human activities contributes as much as 80 percent of the iron falling on the ocean surface, even in the dusty North Atlantic Ocean, and is likely underestimated worldwide, according to a new study in Nature Communications.

The RV Knorr was operated by Woods Hole Oceanographic Institution from 1970-2016. It was used on the GEOTRACES expeditions in 2010-2011 during which iron aerosol samples were collected for the study led by the USF College of Marine Science. Credit: University of South Florida
