Huge iceberg set to break off Mertz Glacier
Updated
A massive iceberg with enough freshwater in it to fill Sydney Harbour 135 times is about to break off the Mertz glacier in Antarctica. The iceberg will be 75 kilometres long and contains 750 thousand gigalitres of ice. Scientists are not sure if it's a natural event, or if global warming is to blame. But a joint Australian and French team hope to find out.
