Surface meltwater lakes can destabilize ice shelves through the process of hydrofracture, thereby reducing their buttressing effect and causing sea level to rise. Here, we present remotely sensed observations of repeated, rapid drainages of a ~4.3 km2 supraglacial lake on Amery ice shelf. We describe lake evolution and volume variations using ultra-high-resolution (~0.5 m) optical imagery and digital elevation models. Our research aims to advance the understanding of surface melt on ice shelf stability.
