I am home. I have a lot of catching up to do. The dark at night is nice.
I was asked what the sounds of Antarctica are like. In McMurdo there is always noices of machinery. The helos warming up and taking off (right next to our shop), The power plant generators, although equipped with large mufflers drone on 24/7. You are also hear diesels 24 hours a day and back up alarmas as materials, snow, or earth get moved around. The wind is continuous. The wind noise is almost aways cutting through the other noices. Out in the field noise is totally different. It is so quiet. It is so incrediblely quiet. You can year a helicopter 30 or 40 miles away. On the polar plateu the sound carries fairly well. The ice is just like dense strofoam. It squeaks like styrofoam and sounds bounce of it (and transmits vibrations) just like stryofoam.
