The world’s largest iceberg may now be trapped in a giant whirlpool of water. Satellite images show that the colossus, named A23a, has been orbiting itself in the Southern Ocean for several months. The British broadcaster BBC quoted experts as saying that the iceberg may not be able to escape the so-called Taylor column for many years.
However, this also prevented the colossi from being carried by ocean currents to warmer climates and melting faster. The BBC quoted Open University polar expert Mark Brandon as saying: “A23a is an iceberg that refuses to die.”
A23a broke away from Antarctica’s Filschner-Ronny Ice Shelf in 1986 but remained attached to the seafloor for decades. After breaking away in 2000, he temporarily made a spurt of progress, but stayed in one place.
The British Antarctic Survey’s polar research agency announced on Platform A23a takes 24 days to complete a round.
The iceberg covers an area of approximately 4,000 square kilometers, 4.5 times the area of Berlin. Meanwhile, as photos from a ship owned by Eyos Expeditions show in mid-January, waves and weather have carved massive arches and cavernous depressions into the behemoth.
According to the European Space Agency ESA, icebergs from the so-called Weddell Zone often reach the South Atlantic and melt.
