The A23a iceberg, the largest globally, has grounded approximately 70km from South Georgia, easing concerns of wildlife disruption. The iceberg, measuring 3,300 sq km and weighing around 1 trillion tonnes, has been drifting north from Antarctica since 2020. If it stays grounded, the British Antarctic Survey's Andrew Meijers indicated that local wildlife, including penguins and seals, could remain unaffected. Historic observations show that icebergs following this path usually break up or melt. The iceberg, which calved in 1986, has notably not shown expected fragmentation despite previous concerns about its proximity to critical breeding grounds.
The colossal iceberg A23a, measuring 3,300 sq km and weighing nearly 1 trillion tonnes, has run aground near South Georgia, potentially sparing wildlife.
Oceanographer Andrew Meijers noted that if the A23a iceberg remains grounded, it is not expected to significantly impact the local wildlife population.
The biggest iceberg calved from the Antarctic shelf in 1986 and embarked on a northward journey in 2020, drawing concerns for potential wildlife disruption.
Despite previous fears of collision, the latest observations reveal that A23a is stuck 73km from South Georgia since March 1.
