An area known as the "Last Ice" in the Arctic had developed a huge hole, causing concern among researchers for the area considered to have the oldest and thickest ice in the region.
The hole in the ice, also known as a polynya, is located north of Ellesmere Island, Canada's northern-most island and just west of Greenland. Researchers at the University of Toronto-Mississauga found the polynya formed on May 14, 2020. One day later, it had expanded about 62 miles long and 18 miles wide before closing off on May 26.
