Trace metal chemistry: less is more by Tim Conway

Dr. Tim Conway from University of South Florida brings a wealth of understanding of trace metals…

One billion liters of seawater would be required to gather just 25 grams of iron, yet this trace element is essential to every form of life on the planet.  A group of scarce but biologically important elements in the ocean, referred to as trace metals, can either limit the growth of organisms or be toxic, depending on the concentration.  Dr. Tim Conway brings a wealth of understanding of trace metals, in part due to extensive interaction with the International GEOTRACES program, a study of the marine biogeochemical cycles of trace elements and their isotopes…
