Dear David,
The SO is presently absorbing about 4.4 GT annually (Landschutzer,
P.,/et al/.Science349,1221–1224(2015). To increase that by 1 GT would
require about 1/20 to 1/50 the area based on our field, SOFeX,
observation and the modeling work using the LANL Biogeochemical POP model.
Regards,
Oliver Wingenter

Does anyone have any ideas of the area of ocean that would be required
to absorb 1 gigaton of CO2 if properly fertilized? It would be
interesting to understand the potential sized area required for this
and the possible volume of nutrients required. Usual caveats about
that this has not been tried and studied properly yet apply. I am
trying to get an idea of scale of this. It would also be useful to
understand the potential fishing stock increase for the area in
question. Increased fishing could give an economic underpinning to
ocean fertilization.
