New research led by the British Antarctic Survey shows West Antarctica's ice melt currently contributes nearly 10 percent of the global sea level rise.
An international team of researchers -- including scientists from the Lamont-Doherty Earth Observatory at Columbia University in New York and the Britain's National Oceanography Center -- identified the antarctic's Pine Island Glacier as a major source of the ice melt.
Officials said the project is part of a series of investigations to better understand the impact of melting antarctic ice on sea level.
The scientists said they used an autonomous underwater vehicle to dive beneath the Pine Island Glacier's floating ice shelf and discovered a 985-foot-high ridge (mountain) on the sea floor.
