Deep Sea Iron Fertilization Productive

07-28-2011 • arclein

Phytoplankton growth in many areas of the open ocean is limited by the low availability of iron, despite the presence of high concentrations of other nutrients. Relatively small-scale experiments have shown that fertilising such areas with iron increases phytoplankton growth. Therefore, adding large amounts of iron over long periods of time should increase the magnitude of the biological carbon pump.
