Chicago-Sized Iceberg Hid Ancient Ecosystem, Scientists Reveal
With the icebergs covering the seafloor, organisms below the shelf cannot get nutrients for survival from the surface. The team hypothesized that ocean currents are a critical driver for life beneath the ice sheets. The team also collected data on the larger ice sheet, whose shrinking size spells concern for the animals that live beneath it.
Giant iceberg breaks from Antarctica, revealing mysterious underwater ecosystems
On January 13, 2025, iceberg A-84, which is roughly the size of Chicago, broke from the George VI Ice Shelf, a giant floating glacier attached to the Antarctic Peninsula ice sheet, leading to the discovery of new aquatic species and a healthy, untouched ecosystem.
A hidden ecosystem of giant sea spiders, octopuses, and other stunning sea creatures shows how life can flourish even when sealed off from the surface by a thick layer of ice.
