no satellite or surface ship could trace. The seven‑meter vehicle followed a pre‑programmed itinerary under the Dotson Ice Shelf, operating out of contact with the research vessel that deployed it. Once it entered the hidden cavity, scientists could...

Arctic, which had persisted for millennia, has vanished. Scientific analysis confirms that the 2020 collapse of the Milne Ice Shelf resulted in the total drainage of Canada’s final epishelf lake, effectively erasing a rare, stratified ecosystem that...

autonomous underwater vehicle known as Ran, a bright orange, seven-meter-long robot, vanished beneath the massive Dotson Ice Shelf in West Antarctica. Despite being programmed for a specific route under hundreds of meters of solid ice, the craft failed...

we know about the hidden world beneath the frozen continent. In 2009 a research team descending through Antarctica’s Ross Ice Shelf made a startling find: a shrimp‑like crustacean thriving beneath more than 180 meters (600 feet) of solid ice. The...

LASSIE (Low‑Altitude Survey System for Icefish), spent two full days gliding over the seabed beneath Antarctica’s Filchner Ice Shelf. The mission verified that an estimated 60 million active nests persist in the Weddell Sea, confirming the continuity of...

of the A68 iceberg, a massive slab of ice roughly 5,800 square kilometers in size that broke away from the Larsen C Ice Shelf. The removal of this ice cover provided a rare window for researchers to explore the previously inaccessible seafloor. While...

krill, worms, crustaceans, copepods, and crab larvae, with some organisms observed resting directly on the submerged ice shelf. “The initial idea for the ROV was to see what happens to the meltwater once it gets released into the ocean,” explained...

The timing of these observations was made possible by the 2017 calving of the massive A68 iceberg from the Larsen C Ice Shelf. The event exposed previously inaccessible swaths of the seafloor, allowing scientists to study habitats that had been shrouded...
