Giant iceberg makes its way to an island

Giant iceberg makes its way to an island

One of the largest icebergs ever discovered, A23a, is moving towards the isolated island of South Georgia in the South Atlantic, endangering the habitats of many species that live there.

With an area of ​​3,500 square kilometers and a weight of about 1 trillion tons, A23a broke away from Antarctica in 1986 and remained stranded near the coast for more than 30 years, until it began to move in 2020.

Currently, sea currents have steered it on a course that is expected to bring it near South Georgia in 2-4 weeks.

Experts warn that if the iceberg hits the island's shores and breaks apart, it could block access to surrounding waters, threatening the livelihoods of seals and penguins that breed there. In addition, the 40-50 meter high ice "wall" poses an ecological threat to the area.

However, the melting of the iceberg will enrich the waters with nutrients that favor the growth of phytoplankton, a key food source for whales and other marine organisms.

Scientists hope that this phenomenon will help study the absorption of carbon dioxide by phytoplankton, providing new insights into its impact on the global ecosystem.
