Silence is a presence, rather than an absence, in Antarctica, and to experience it away from the chatter of people or penguins and let your ears penetrate beyond the crackle of ice and the lap of the sea is to hear something else. The unknown of the great southland was never considered void, though often appeared on maps as blank. “It has always been our ambition to get inside that white space ... so the space can no longer be a blank”, wrote Robert Falcon Scott. Pre-trip, you might have a mind brimming with Antarctic imagery, history and stories, but once you’ve been there, its richness and your understanding of it intensifies. You’ll know much more of the Antarctic, have a feel for it, and realise that some things cannot be captured by words or photographs, or by any representations beyond the real thing.
