Surprisingly large hole found in Arctic’s most stable ice

A hole was discovered in the Arctic's oldest ice, previously thought stable. A May 2020 storm near Ellesmere Island caused a crack, forming a polinia. This open water area, usually ice-covered, was 30 km wide and 100 km long. The study highlights the ice's vulnerability, affecting species like walruses and seabirds. The polinia closed by May 26, 2020, but future occurrences may increase.
