The workshop had two major components: a review of current issues and projects regarding dissolution Of CO{sub 2} in the ocean followed by a specific proposal for a field experiment in a Norwegian fjord. Attachment I contains the agenda and participants for the meeting. Attachment II summarizes each presentation. The challenge of ocean dissolution Of CO{sub 2} involves understanding the trade-offs between costs, benefits (length Of CO{sub 2} sequestration), and environmental impacts (both from direct CO{sub 2} injection and from indirect dissolution as is occurring today). It is quite apparent that we still require a great deal more information than exists today to make rational decisions. Specifically, we need more research directed at the technology for dissolving the CO{sub 2} and at understanding the environmental impacts. While paper studies and laboratory experience are useful, we are approaching the time to move our research into the field. While attendees thought a field experiment in a Norwegian fjord would be a useful exercise, two key concerns were aired: (1) We need to better understand the goals of this experiment and how it relates to the bigger picture. To address this concern a comprehensive list of research needs should be generated. Then, a list of possible field experiments (including the Norwegian fjord) should be generated that allow us to address these questions. (2) Not enough details were presented on the Norwegian fjord experiment. For example, a key question is the scale (i.e. CO{sub 2} flow rate, duration) of the experiment. A follow-up action is to generate a more detailed experimental plan. In summary, the workshop left the following impressions. (3) More research is required to understand the role CO{sub 2} dissolution in the ocean can lay in mitigating global climate change. Field experiments will be required and the timing should be soon. (4) More work is required in developing a research plan for field experiments
