Because of carbon dioxide's potential role in global warming, there is considerable interest in methods of long-term sequestering of anthropogenic emissions of CO[sub 2] outside of the atmosphere. The work reported here predicts the effect of hydrate formation on the fate of CO[sub 2] droplets discharged into the ocean under hydrate-forming conditions. New information on hydrate growth rates recently determined by one of the authors is incorporated into the model. It is seen that hydrate film formation on CO[sub 2] droplets into the deep ocean will increase estimates of required injection depths and decrease the maximum allowable droplet size suitable for effective sequestration to occur. 13 refs., 2 figs.
