New study reveals seafloor volcanoes may have played a greater role in natural ocean iron fertilizer (IMAGE)
Caption
A computer model shows how iron released by deep-sea hydrothermal vents could have spread through the Pacific Ocean during ice-age sea-level declines. Developed by a team led by Boston College researcherrs, the modeled pathway helps illustrate how enhanced seafloor volcanism during ice-age transitions may have supplied iron to surface waters, fertilizing plankton in an iron-limited region.
