Iron Importance

Scientists at CCE have determined that supply of the trace element iron can limit phytoplankton growth in the southern California Current System, in both surface and subsurface phytoplankton communities. This finding has implications for ecosystem productivity and associated services, including fisheries and carbon sequestration in deep ocean waters.
