    Concerns about rising levels of CO2 in the atmosphere have led to investigation of a variety of alternatives for possible disposal of a portion of the CO2 now vented to the atmosphere. This talk reports on a series of experiments conducted in Monterey Bay with the research vessels Point Lobos and Western Flyer, and the remotely operated vehicles Ventana and Tiburon. In the experiments, liquid CO2 was released from Ventana and the resulting interactions of the CO2 and seawater observed. When the depth of release was below about 350 m, substantial quantities of CO2 hydrate were formed as rinds of hydrate around bubbles of liquid CO2. At depths below 3000 m, the liquid CO2 was denser than the surrounding water, and hydrate formation occurred rapidly, but no layer of hydrate formed between the water and CO2. Instead, precipitated hydrate rained down into the liquid CO2, causing it to appear to expand. The experiments performed to date suggest that the time scale for exchange of CO2 with seawater will be strongly influenced by the rates of creation and dissolution of hydrate.
