The hissing of the Ross ice floe, the largest in Antarctica, is wonderfully strange. It's also potentially a magic wand for changes to the composition of shelves that can be monitored in real time.

Listening, we think of the first groan of Fever Ray's song, "If I Had A Heart", or the dramatic composition inuksuit from John Luther Adams:

To arrive at their new record, twelve scientists working on the pack ice have excavated 34 tools to measure the seismic activity in it, hoping to monitor its internal vibrations. However, they noticed that the surface glazing covering the "firn" – the highest layer of snow on the plateau – fed their sensors with noise.

But what was originally thought to be "awkward ambient noise," as glaciologist Douglas R. MacAyeal summed up in a summary of the new discoveries, eventually provided insight into the effects of meltwater on this layer structural integrity of the plateau. Does it mean that it will break or not and so raise the sea level? Not bad for a whistle or two.

More music from the natural world

Quintron, a New Orleans-based artist, has developed, through Quintronics, the Weather Warlock, a "giant analog synth" based on a C major chord, but whose music varies according to weather conditions (temperature, wind, etc.). sun and rain) that he experiences at a given moment. The result, which you can broadcast 24 hours a day from your current home in Los Angeles, is mercurial and meditative and deserves to be left in your headphones for a while. "We hope that this instrument could be useful for people suffering from any type of sleep disorder or anyone suffering from stress or health problems who can benefit from a direct musical link with nature," note its creators. (They also note that this is do not intended to provide medical treatment.)

The Baka of South-East Cameroon use water as a drum, which gives a fluid and soothing rhythmic form.

Or, if you're fed up with the Earth, NASA has a spooky "Spooky" space sound archive perfect for Halloween. (Not so sure of this cover art, though.)
