I have written a proposal with Staša Puškarić to the EU some years ago, and find immense fascination with his concepts and ideas. However, the mechanisms that he proposed for the stimulation of the biological pump of the ocean is so far from mainstream that the research councils tend to ignore their factual basis. There is a long way from the observations and ideas developed in the Adriatic Sea to a viable geoengeneering technique, but clearly it would be well worthwhile to have the research done to test his hypothesis.
