But Chilean scientists are worried because the organization grew out of a for-profit company, Oceaneos Environmental Solutions of Vancouver, that has sought to patent iron-fertilization technologies.

The Oceaneos foundation has accused the scientists of improperly classifying its work as geoengineering, rather than ocean restoration.

* Iron in some parts of the Ocean are at 2-4 parts per trillion when it should be at 10-15 parts per trillion for healthy amounts of plankton and algae.
* Tens of millions of tons of soil is blown into the ocean from deserts. That soil is 1 to 5% iron. Volcanoes also naturally deposit a lot of earth materials with iron into the oceans
* The 120 ton iron dumping in 2012 generated record salmon harvests in 2013 and 2014. The 2012 iron fertilization generated an algae bloom that fed salmon at the right time to boost the salmon population
* the salmon bloom died in days and then fell to the bottom of the ocean taking large amounts of CO2 with them
