The next to the last article mentions the Haida Gwaii experiment.

"Meanwhile, the controversy over iron fertilization as a geoengineering approach rages on. As the vision of a climate-tweaking tool has waned, some companies have attempted to apply the idea to revitalize fisheries. In a highly controversial 2012 example, American businessman Russ George persuaded members of the Haida Nation to fund the dumping of roughly 100 tons of iron sulfate off the coast of Canada, fertilizing a 10,000-square-kilometer algae bloom. George sold the controversial project as a way to boost salmon populations and sequester carbon, but follow-up studies failed to find conclusive evidence that it worked."

That was a very informative article. I'd hypothesize that a potential reason for the less-than-expected results is the fact that the Ocean is a HUGE space with constantly moving water (dilution). It's next to impossible to have an unspoiled 'control sample' within that environment because you are not really in 'control' of any part of said environment. Look at the Marshall Islands and Fukashima as examples of dilution. Radiation is still around the immediate source sites, but it drastically tapers off once you get a very short distance away. The ocean is very good at cleaning herself.
