Well, yes, however there is a net sequestration of phytoplankton, the
detritus of which settles to the abyssal floor and is integrated into
methane hydrates by the benthic ecosystem. This is a significant
amount, and given the economies of scale developed from any exponential
growth mechanism, seeding oceans with rust will sequester significantly
more CO2 than is liberated from refining iron ore.
