Guardian: Ocean Iron Fertilization Is A Viable Way To Sequester CO2

The Guardian analyzes the LOHAFEX cruise and recent science article in Nature on a natural iron-stimulated bloom near the Crozet Islands in Antarctic waters.

"In the latest research, published tomorrow in Nature, the Southampton scientists studied a natural source of iron into the sea near the Crozet Islands at the northern boundary of the Southern Ocean, 1,400 miles south-east of South Africa. Their work showed that iron – which is added by the volcanic rocks to the north but not to the south of the island – successfully tripled the growth of phytoplankton and also the amount that sank to the bottom of the sea.

The Guardian writes that question still remain on how OIF would best be implemented to ensure safety and efficacy, and present a quote by Dr. Andy Watson on recent LOHAFEX controversy:

"It's interesting that [the Polarstern] has been at the centre of a lot of controversy because they wanted to do an artificial experiment with 10 or 15 tonnes of iron. As this [Southampton] paper shows, much larger amounts of iron are being added daily by natural processes around the Crozet Island, and it doesn't seem to have done the Antarctic ecosystem any harm."
