The german Alfred-Wegener-Institute is transmitting a MP3-livestream from Antarctica. They put four hydrophones 70 m underneath the shelf ice and 90 m above the ocean ground through drilled holes in the thick ice sheet. In close proximity to the open water the microphones catch the calls of sea mammals living in this remote region. The scientists in their homebase Bremerhaven are able to analyze the behaviour of whales and seals just as it happens. Only occasionally the electronic-sounding concierto of the seals is interrupted by calving glaciers and colliding icebergs. This recording though baffled the scientists because it doesn’t belong to any sea creature known and nobody heard ice breaking like this before. It’s your guess. The Alfred Wegener Institute gratefully let me use this recording in my piece frost pattern.

Fantastic!
Too sad the PALAOA livestream seems to be not available any longer. All links are offline.
Your “frost pattern” link seems not to work too.
Hi, it’s true, I just updated my homepage and all permalinks are broken. Here is the new one:

And yes, I recently looked at the website of the Wegener Institut and couldn’t find the PALAOA livestream. Too sad. Maybe it was too expensive in the long run…
I listened to this mic very frequently up until it stopped broadcasting. My guess is that the microphone had a malfunction, as it randomly stopped broadcasting/recording data. Then the links were pulled down over a month later. I inquired PALAOA about it, but they never responded back. It’s a too bad it’s gone.
