The distribution of DFe depends on its chemistry, sinks, and internal cycling, sources and transport. The chemistry of Fe in modern oxygenated oceans is characterized by its very low solubility (0.1–0.2 nM) [6]. However, complexation of Fe by organic Fe-binding ligands increases the solubility of Fe [15], [16].

Iron is vital to plant, animal and microbial life. Nearly all organisms ingest it in the course of daily life. If scientists can devise a method to distinguish between iron that has been processed by a living organism and iron that has not been metabolized, they will have a way to measure the distribution of microbes on Earth billions of years ago.
