Short summary
Buried glacier ice is widespread in Arctic regions that were once covered by glaciers and ice sheets. In this study, we investigated the influence of buried glacier ice on the formation of Arctic tundra lakes on Bylot Island, Nunavut. Our results suggest that initiation of deeper lakes was triggered by the melting of buried glacier ice. Given future climate projections, the melting of glacier ice permafrost could create new aquatic ecosystems and strongly modify existing ones.
