Hidden World Under Antarctica Ice Reveals 300+ Canyons With Global Climate Consequences
A vast and previously hidden world has been uncovered beneath Antarctica icy perimeter, revealing a network of 332 submarine canyons that are reshaping scientists’ understanding of ocean currents and the pace of global sea-level rise. A new, highly detailed map of the Antarctic seafloor, published in the journal Marine Geology, shows that these immense geological features are key conduits for the flow of water, heat, and sediment, directly influencing the melting of ice shelves.
A Dynamic Seafloor Revealed
The research, which utilized high-resolution bathymetric data from over 40 international expeditions, identified five times more canyons than had ever been catalogued before. The study found a dramatic contrast between the eastern and western margins of the continent.
