Pacific iron fertilisation is 'blatant violation' of international regulations

Controversial US businessman's geoengineering scheme off west coast of Canada contravenes two UN conventions...

 

A controversial American businessman dumped around 100 tonnes of iron sulphate into the Pacific Ocean as part of a geoengineering scheme off the west coast of Canada in July, a Guardian investigation can reveal.

 

Lawyers, environmentalists and civil society groups are calling it a "blatant violation" of two international moratoria and the news is likely to spark outrage at a United Nations environmental summit taking place in India this week.

 

Satellite images appear to confirm the claim by Californian Russ George that the iron has spawned an artificial plankton bloom as large as 10,000 square kilometres. The intention is for the plankton to absorb carbon dioxide and then sink to the ocean bed – a geoengineering technique known as ocean fertilisation that he hopes will net lucrative carbon credits.

 

George is the former chief executive of Planktos Inc, whose previous failed efforts to conduct large-scale commercial dumps near the Galapagos and Canary Islands led to his vessels being barred from ports by the Spanish and Ecuadorean governments. The US Environmental Protection Agency warned him that flying a US flag for his Galapagos project would violate US laws, and his activities are credited in part to the passing of international moratoria at the United Nations limiting ocean fertilisation experiments

 

Scientists are debating whether iron fertilisation can lock carbon into the deep ocean over the long term, and have raised concerns that it can irreparably harm ocean ecosystems, produce toxic tides and lifeless waters, and worsen ocean acidification and global warming.

Great ocean garbage patches 'share' plastic waste – with VIDEO - environmentalresearchweb

Great ocean garbage patches 'share' plastic waste – with VIDEO - environmentalresearchweb | Ecology | Scoop.it

"The patches are an international problem," said researcher Erik van Sebille in a video abstract for Environmental Research Letters (ERL). "It is not that plastic from one country ends up in one particular patch. Quite the contrary, all of the plastic ends up in all of the patches, and the patches are interconnected in a way that we didn't know before."

Van Sebille and colleagues' model of plastic dispersion is the first to include seasonal variations in ocean currents and to vary the amount of plastic entering the ocean according to the number of people living near each coast.

There are currently five garbage patches, formed at a gyre – a system of rotating ocean currents – in each of the world's subtropical ocean basins. A garbage patch is also likely to form in the Barents Sea in the Arctic within the next 50 years or so, the team's model revealed.
