RedOrbit: A newly-discovered source of oceanic bioavailable iron could have a major impact on our understanding of marine food chains and global warming. A UK team, including researchers from the University of Bristol, has found that summer meltwaters from ice sheets are rich in iron, which will have important implications on phytoplankton growth. Their findings are reported today in Nature Communications.
It is well known that bioavailable iron boosts phytoplankton growth in many of the Earths oceans....
