Abstract

This paper assesses how parameter uncertainties in the model for rise velocity of CO2 droplets in the ocean cause
uncertainties in their rise and dissolution in marine waters. The parameter uncertainties in the rise velocity for both
hydrate coated and hydrate free droplets are estimated from experiment data. Thereafter the rise velocity is coupled
with a mass transfer model to simulate the fate of dissolution of a single droplet.
The assessment shows that parameter uncertainties are highest for large droplets. However, it is also shown
that in some circumstances varying the temperature gives significant change in rise distance of droplets.
