My Last Balloon Flight in Antarctica
Time flies by, and the ozone season is over. The ozone will replenish itself as daylight strikes the stratosphere. Chlorine atoms our parents released into the stratosphere unfortunately will remain there for at least another twenty years. They will continue each spring to attack ozone and all who are under this atmospheric hole shall be subject to the dangers of UV light exposure. It is a problem that would have been catastrophic had scientists not alerted government leaders who enacted laws to protect our planet. It is a true scientific success story and now I can say I was a part of it. This story is a reminder to all that environmental vigilance is essential to our survival as we continue engineering our planet.
Today I spent time with Marianne who works with the B15 iceberg group. We experimented with a strain gauge that would in principle measure any movement of the ice shelf. It was a genuinely good time to be out on the shelf digging away though I was a bit skeptical that this instrument would work.
Later we launched my last balloon flight in Antarctica. It was pleasant to watch it ascend into the beauty of the blue sky.
Tomorrow marks my last day here. A full two and one half months after I began, I shall fly back to Oregon to see the green again. Before I leave I shall go up Ob Hill and listen to the glaciers talk.
