A23a World’s Largest Iceberg is on the Move After 30 Years

The iceberg A23a the largest in the world has finally broken free from its three-decade-long anchorage to the ocean floor in the Weddell Sea. This block of ice measuring 4,000 sq km (1,500 sq miles) more than twice the size of Greater London, had initially split from the Antarctic coastline in 1986. However, it quickly became grounded, earning itself the status of an ice island. After 30 years of immobility.

A23a’s size is with a thickness of approximately 400m (1,312 ft), surpassing structures like the London Shard.

Originating from the outbreak of icebergs from the Filchner Ice Shelf in Antarctica, A23a’s calving coincided with a Soviet research station situated on the White Continent in 1986. The urgency to retrieve equipment from the Druzhnaya 1 base due to the iceberg’s detachment.

Dr. Andrew Fleming a remote sensing expert from the British Antarctic Survey, suggests that the consensus among experts is that the time had simply come for A23a to decrease in size sufficiently to lose its grip and start moving.

Although there was speculation about changes in shelf water temperatures, the view is that this colossal iceberg was destined to stir from its lengthy slumber. Dr. Fleming first detected signs of movement in 2020, marking the beginning of A23a’s journey.

Recent months have witnessed a noticeable acceleration in A23a’s movement driven by winds and currents.
