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.

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.

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