On January 14th on my recent expedition to Antarctica with EYOS Expeditions, we sailed past Iceberg A23a, currently the largest iceberg on the planet. The enormous tabular iceberg is approximately 40 nautical miles, up to 400 metres thick and weighs just short of a trillion tonnes. Expedition leader Ian Strachan and I used a drone to photograph the iceberg, capturing images of man dramatic archways and caves that were appearing due to wave action and warmer waters as the berg drifts north. The images quickly got the attention of the BBC, who ran a story that evening with our footage and it is shared here below, along with a collection of our raw footage.
