The friction of ice on other materials controls loading on offshore structures and vessels in the Arctic. However, ice friction is\ncomplicated, because ice in nature exists near to its melting point. Frictional heating can cause local softening and perhaps melting\nand lubrication, thus affecting the friction and creating a feedback loop. Ice friction is therefore likely to depend on sliding speed\nand sliding history, as well as bulk temperature.The roughness of the sliding materials may also affect the friction. Here we present\nresults of a series of laboratory experiments, sliding saline ice on aluminium, and controlling for roughness and temperature. We\nfind that the friction of saline ice on aluminium
