Planktos to Begin Ocean Seeding
Trials of a carbon sequestration project which involves seeding the ocean with iron particles are to take place later this month. Planktos are attempting to create a carbon offset product based on stimulating plankton growth. By adding iron to certain areas of the sea, the company can promote growth which they hope will absorb large amounts of carbon. This will then sink to the ocean floor, mostly in the form of feaces, where it will remain for several centuries. It's not a new concept, and has been trialed before. However, whilst many studies have had success promoting plankton growth, few have seen an increase in the amount of ...
