According to scientists, the world’s largest iceberg is moving again for the first time in three decades. Existing satellite images showed that the iceberg called A23a was drifting relatively quickly across the northern tip of the Antarctic Peninsula, it was said today. Strong winds and currents support this.
The glacier has an area of about 4,000 square kilometres. It remained largely stationary for decades after landing on the ocean floor. According to experts, it is not clear why the iceberg started moving now.
Expert Oliver Marsh of the British Antarctic Survey said: “It has likely weakened slightly over time and gained some extra buoyancy, allowing it to rise from the sea floor and be moved by ocean currents.” A23a could again run aground off the South Georgia Islands in the South Atlantic. Millions of seals, penguins and seabirds breed on the island and forage for food in the surrounding waters.
