Method annual iron assimilation by phytoplankton was estimated from distributions of satellite-derived oceanic primary production and measured (Fe:C)cellular ratios.
Comments soluble Fe fraction ranging between 1 and 10%. by comparison, upwelling/entrainment supply of dissolved Fe to the upper ocean is small (~0.7x10^9).
