The transition from moving to fast ice in western Viscount Melville Sound

摘要

Reports the ability to differentiate between noise generated by ice in motion and that under shore-fast ice from underwater noise recorded by a remote instrument package (RIP) installed in the sea bottom south of Melville Island, Aug 1967-Aug 1968. Strip chart records of both ice types are shown, that for fast ice with wind speed and air temperatures at Mould Bay, Prince Patrick Island. Contrary to expectations, the ice cover was frequently in motion during Dec. Little correlation existed between the wind speed and the existence of motion.
