Study Finds Deep Ocean Is Source Of Dissolved Iron In Central Pacific

A new study led by scientists at the Woods Hole Oceanographic Institution (WHOI) points to the deep ocean as a major source of dissolved iron in the central Pacific Ocean. This finding highlights the vital role ocean mixing plays in determining whether deep sources of iron reach the surface-dwelling life that need it to survive. "Our study is a long-term view--over the past 76 million years--of where iron has been coming from in the central Pacific," says Tristan Horner, a postdoctoral fellow in the Marine Chemistry and Geochemistry Department at WHOI and lead author of the paper to be published February 3, 2015, in Proceedings of the National Academy of Sciences. read more
