The iceberg A23a, the world's largest, has grounded near South Georgia after drifting from Antarctica's Filchner ice shelf. Weighing nearly one trillion tonnes, it has significant implications for local marine life and fishing. While scientists believe that A23a's grounding may boost food sources for wildlife like penguins and seals, there are concerns regarding hazardous conditions for fishing vessels. A23a has been monitored since 2020, and its limited movement suggests that while it may not impact local wildlife severely, the eventual breakup and melting process could have mixed effects on the ecosystem.
The world's largest iceberg, A23a, has run aground near South Georgia, posing potential hazards to fishing but could boost local wildlife food sources.
The British Antarctic Survey is closely monitoring iceberg A23a, which has drifted since 2020 and could impact local fisheries as it eventually breaks up.
Dr Andrew Meijers from BAS noted that if A23a remains grounded, it is unlikely to have a significant impact on South Georgia's wildlife.
Despite its sizable presence, A23a's grounding could enhance nutrient levels, benefiting penguins and seals by increasing available food resources.
