The Ayles Ice Shelf was one of six major ice shelves in Canada, all on the north coast of Ellesmere Island, Nunavut. The ice shelf broke off from the coast on August 13, 2005, forming a giant ice island 37 metres (121 ft) thick and measuring around 14 km (8.7 mi) by 5 km (3.1 mi) in size (approximately 66 km² or 25.5 mi (41.0 km)² in area or 2.6 km³ in volume). The oldest ice in the ice shelf is believed to be over 3,000 years old. The ice shelf was at (83°1.5′N 77°33.5′W / 83.025°N 77.5583°W / 83.025; -77.5583), approximately 800 km (500 mi) south of the North Pole.
The Ayles Ice Shelf, like the nearby Mount Ayles, was named for the Arctic explorer Adam Ayles, who served under George Nares as the Petty Officer of HMS Alert in the British Arctic Expedition. A 1986 survey of Canadian ice shelves found that 48 square km (3.3 cubic km) of ice calved from the Milne and Ayles ice shelves between 1959 and 1974.
