      abstract = {Diurnal depth cycles of decimeter scale are observed in a  supraglacial lake on the McMurdo Ice Shelf, Antarctica. We  evaluate two possible causes: (1) tidal tilt of the ice  shelf in response to the underlying ocean tide, and (2)  meltwater input variation. We find the latter to be the  most likely explanation of our observations. However, we do  not rule out tidal tilt as a source of centimeter scale  variations, and point to the possibility that other, larger  supraglacial lake systems, particularly those on ice  shelves that experience higher amplitude tidal tilts, such  as in the Weddell Sea, may have depth cycles driven by  ocean tide. The broader significance of diurnal cycles in  meltwater depth is that, under circumstances where the ice  shelf is thin, tidal-tilt amplitudes are high, and  meltwater runoff rates are large, there may be associated  flexure stresses that can contribute to ice-shelf fracture  and destabilization. For the McMurdo Ice Shelf (~20–50 m  thickness, ~ 1 m tidal amplitude and ~10 cm water-depth  variations), these stresses amount to several 10's of kPa.},
