More Weird Glacier Sounds

January 4th, 2008 andrea

commonwealth met station
Today Hassan and I went to visit a couple more LTER met stations, one on top of Commonwealth Glacier in Taylor Valley. If you put a mic right down to the surface, the sound of a glacier is incredibly reverberant, almost as sound was going into a giant hollow space with highly reflective walls or through a tangled matrix of hollow glass tubes. It was too cold to record any melting sounds underneath the surface, but I was able to scrape and otherwise manipulate the surface to get some interesting and weird sounds. What I find weird in this short mono recording is the kind of high pitched squeaking and clicking that occurs behind the main scraping sound.
