What the heck is iron dust supposed to do?
The dust will get wet:)
Actually is supposed to help spawn plankton. I went ahead and read the article:)
Feed the fish??
It is supposed to cause an algea bloom which then dies when runs out of iron. The biomass then sinks trapping the carbon at the sea bottom.
Low natural levels of iron is sea water limit plankton and other plant growth. Adding iron dust is essentially fertilizer for them. More plant growth eats more CO2 and feeds more fish. Hmm, maybe we need to bring back sub warfare to fix the oceans. LOTS of iron added to the oceans during WWII.

The iron spawned the growth of enormous amounts of plankton, which Mr. George, a former fisheries and forestry worker, said might allow the project to meet one of its goals: aiding the recovery of the local salmon fishery for the native Haida.
Plankton absorbs carbon dioxide, the predominant greenhouse gas, and settles deep in the ocean when it dies, sequestering carbon. The Haida had hoped that by burying carbon, they could also sell so-called carbon offset credits to companies and make money.
Iron fertilization is contentious because it is associated with geoengineering, a set of proposed strategies for counteracting global warming through the deliberate manipulation of the environment. Many experts have argued that scientists should be researching such geoengineering techniques — like spewing compounds into the atmosphere to reflect more sunlight or using sophisticated machines to remove carbon dioxide from the air.
