A groundbreaking new map,Bedmap3, has provided the most detailed view yet of the hidden landscape beneath Antarctica’s ice sheet, revealing towering mountains, deep valleys, and critical grounding lines where ice meets the ocean.

As the planet heats up and Antarctica’s ice sheet melts at a faster pace, scientists warn of a steady rise in sea levels.

The most detailed map yet of the landscape beneath Antarctica's ice sheet has been assembled by a team of international scientists led from the British Antarctic Survey (BAS).

Scientists from New Brunswick are part of Canada's expedition to Antarctica mapping the ocean floor trying to better understand what's happening to sea life and geological history as the climate warms and freshwater glaciers melt.
