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.

As the planet warms, Antarctica's ice sheet is melting and contributing to sea-level rise around the globe. Antarctica holds enough frozen water to raise global sea levels by 190 feet, so precisely predicting how it will move and melt now and in the future is vital for protecting coastal areas.

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.
