Thank you.
Thank you to the witnesses for being here this morning.
Dr. Dixon, the impression I got at the very beginning of your presentation was that there's still a lot of research to do surrounding water and the oil sands before we can really put our finger on what's going on there. Yet I get another message--and I don't know if it's from Dr. Barker or from you--that the research has been done; it's just that we haven't been able to pull it together or integrate it. There's that contradiction in my mind. How would you address that? How would you clarify that for me?
