When Adrienne White, an ice analyst at the Canadian Ice Service, sat down at her desk one morning last weekend, the first thing she checked on was Nunavut’s Milne Ice Shelf, located on the northwest coast of Ellesmere Island. On the other side of the island, the most northerly in Canada, the St Patrick’s Bay ice caps completely disappeared.

Located on the northern margin of Canada’s Ellesmere Island, the ice platform split on 30/31 July to form a free-floating bloc some 80 sq km (30 sq miles) in area. As this warm water goes through the ice, it carves out small areas that Mueller and his colleagues recently discovered life inside, “nourishing themselves from the sediments that come from the fiord and are drifting by in the current,” he said.
