For many of us, isolation is disconcerting and challenging, but for wildlife sound recordist Chris Watson, it is something he actively seeks, so he can fully immerse himself in a place and capture its unique sounds in his recordings.

In the first of five illustrated essays, Chris recalls a trip to Antarctica, to a landscape which has been described as ‘The Great White Silence’ to record one of the greatest transitional events on the planet; the sounds of a glacier being transformed over the Antarctic summer from a solid mountain of freshwater ice into the salt water of the Ross Sea.
