Observations show that the flow of Rutford Ice Stream (RIS) is strongly modulated by the ocean tides, with the strongest tidal response at the 14.77-day tidal period ( M sf ). This is striking because this period is absent in the tidal forcing. A number of mechanisms have been proposed to account fo...
