Yes, I can. In 1987 I flew over the northern depression measuring ozone. We have a vortex that goes around the North Pole, and it takes three weeks in the spring to complete its circle. If you fly through that vortex in the spring you will see what, until this year, was a depression. I was studying the difference between dynamic depletion and chemical depletion of ozone in that depression.
Canada is famous for its world ozone monitoring network based on an instrument called the Brewer, which was developed by Alan Brewer, a Canadian. Because of that work we flew instruments on the shuttle that measure ozone. We have two satellites now--SCISAT and Odin. Odin is a Swedish satellite, but the instrument is Canadian. We are using them to measure ozone, among other trace elements. The measurements we take show the seriousness of what happened this spring in the Arctic. So it is something we have to look after.
It's a tribute to the leadership of our country that over the last 20 years we've been tracking ozone. We are the best at it. We have the best instrumentation and the best scientists. We're kind of in a parking spot, and we just need to stay there because we're the best at it. We don't have to leave and let someone else take over.
So I have strong feelings that our history in this area is stellar, and the expertise we have developed over the last 20 to 25 years has been nothing short of a service to the rest of the world.
