They were talking about that on the Science Show (ABC RN, repeat 7pm tonight EST) on Sat (or it may have been an excerpt they played from the Catalyst (ABC TV1)) on Baleen Whale poo being important to provide enough iron for phytoplankton growth. The scientist was cautious about 'seeding' as different (larger) phytoplankton grow with artificial iron input. No (little) research has been done on the full impact of this. Problems he suggested not yet researched (from my memory) were:-
impact on food chains,
possible toxic algal blooms,
that the phytoplankton may not be preserved (i.e CO2 be trapped) and
that it possibly could even result in release of Nitrous Oxide or Methane or other worse greenhouse gases ....
