We have a recent one page recent ocean policy forum article in Science that I think would be useful as input to the Geoengineering conference.
It pertains to ocean fertilization and is co-authored by a large group of international scientists who have participated in these experiments and studies. I will be attending the meeting and can provide further input at that time, but it is a short and concise description of the current status and uncertainties of this proposed geoengineering approach that is good background to be shared with others.
Cheers, Ken
