AMD - DIF Record(s) USAP-1443126_1 Abstract During the Austral summer melt season of 2016-2017, an automatic camera was placed overlooking a surface lake feature on the McMurdo Ice Shelf. This camera created a time-lapse video (30 minute photograph time intervals) used to observe the filling and draining of the lake called Rift-Tip Lake located approximately 2 km from the McMurdo Ice Shelf ice front. The data was used in support of a field project to measure the flexural response of the McMurdo Ice Shelf (and ice shelves in general) to the filling and draining of supraglacial lakes. The time-lapse video begins 16 November 2016 and ends 27 January 2017.
