Interactive effects of iron, irradiance and CO 2 on Ross Sea phytoplankton
We conducted a factorial shipboard continuous culture experiment to examine the interactive effects of altered iron, irradiance and CO 2 on the summer phytoplankton community of the Ross Sea, Antarctica. After 18 days of continuous incubation, iron enrichment increased phytoplankton biomass, nutrien...
