Vi simulerede et prækambriske jernholdig marine upwelling-system i et laboratorium-skala lodret gennemstrømning kolonne. Målet var at forstå, hvordan geokemiske profiler af O 2 og Fe (II) udvikle sig som cyanobakterier producere O 2. Resultaterne viser etableringen af en chemocline grundet Fe (II) oxidation af fotosyntetisk produceret O 2.
