Interesting that it increases fish stocks. Iron ore is very cheap compared to fish, and you get many times the weight of fish than you use of iron. Might fishermen be tempted to use this commercially?

Thanks for this Emma, it was really interesting. I particularly liked the detailed discussion on what happens to the CO2 once it has been absorbed by the phytoplankton. This vital part in the process seems to me to be skimmed over too often. The Keller article looks good and I shall return to that when I have more time – I’m sure I’ll end up agreeing with you about timescales. When I was a teenager I remember reading an article by Carl Sagan about using algae to terraform Venus as the algae would supposedly gobble up the CO2 (as of course our Venusian friends have a bigger CO2 problem than us!). I’ll have to look on the internet to see if anybody believes that is still plausible…
