The Milne Ice Shelf, a fragment of the former Ellesmere Ice Shelf, is located in the Qikiqtaaluk Region, Nunavut, Canada. It is the second largest ice shelf in the Arctic Ocean. Situated on the north-west coast of Ellesmere Island, it is about 270km (170miles) west of Alert, Nunavut.
In 1986, the ice shelf had an area of about 290km2, with a central thickness of 100m (300feet).[1] It had been the last ice shelf in the Canadian Arctic to be fully intact until July 2020, when over 40 percent of the sheet collapsed within two days, a consequence of global warming. An uninhabited research camp was lost when the shelf collapsed. It included instruments for measuring water flow through the ice shelf.[2] [3]
