An enormous iceberg, called A-68A, has made headlines over the past weeks as it drifts towards South Georgia in the Southern Ocean. New images, captured by the Copernicus Sentinel-1 mission, show the berg is rotating and potentially drifting westwards.
In July 2017, the lump of ice, more than twice the size of Luxembourg, broke off Antarctica’s Larsen C ice shelf – spawning one of the largest icebergs on record. Now, three years later, the A68A berg is being carried by currents in open waters – thousands of kilometres from its birthplace.
The Copernicus Sentinel-1 mission’s latest acquisition, captured on 25 November, shows the berg’s eastern tip is now just 255 km from South Georgia. If the iceberg were to reach the island’s shores, it could potentially ground in the shallow waters offshore and threaten wildlife, including penguins, seals and krill.
