Alison Ballance made two trips to Antarctica during her 12 years as host of Our Changing World. She also visited ‘virtually’ with an award-winning podcast series that celebrated the sounds of icebergs.

In this week’s icy retrospective, Alison revisits the Voice of the Iceberg series, in which artist Joseph Michael and his team recorded the characters and sounds of icebergs in Antarctica.

In Part 2: Revelation, the varied personalities of different icebergs began to reveal themselves.

Voice of the Iceberg won Best Creative Feature at the 2018 NZ Radio Awards.
