Another Good Piece on Geoengineering: Ocean Upwelling

Another geoengineering scheme that has received some coverage in recent years is artificial ocean upwelling, whereas flap-valve operated ocean pipes are used to upwell nutrient-rich deeper waters to fertilize surface oceans, with the objective of ultimately increasing carbon sequestration. An excellent potential reading in this context is a new study in GRL, A. Oschlies, et [...]
