Over in the Galapagos a research ship is going to seed iron into the ocean waters to highlight the role that phytoplankton play in the absorption of CO2. The theory is that by added iron to the ocean, an essential nutrient used in photosynthesis they may be able to speed up the rate that the oceans absorb CO2.
At certain times of the year very large plankton blooms can even be seen from space but it is hoped that by providing additional iron nutrient these blooms may increase and therefore highlight their role in controlling CO2. There is a slight problem with this exercise in that there is a known situation that can occur with the seeding of iron into the ocean that equally increased the amount of zooplankton (including jellyfish and krill) which then just feed on the extra numbers of phytoplankton, negating the increased organic levels and thus have no impact on CO2 levels.
Nevertheless the crew of the Waterbird II research ship, part of an eco restoration organisation called Planktos indicate that they will be happy just to highlight the theory even if the practical application completely fails.
