With its ice tongue pointing towards Australia and New Zealand, the Mertz Glacier in East Antarctica extends into the Southern Ocean. A glacier can “calve”, which means that pieces of ice break off and start to float in the open sea as icebergs. Often comprising an area of several square kilometres, sea currents make these giants cross the Antarctic for months or even years. However, as soon as they reach northern and warmer areas, they begin to melt.
