Table 1. Radiocarbon ages from ice-dammed lakes at the margin of Russell Glacier and Isunnguata Sermia. Calibration is based on the IntCal13 calibration curves (Reimer et al. Citation2013)

Figure 1. Location in west Greenland of the lake basins considered in this study and of local topography and contemporary ice-margin configuration (A): Image of an approximately 1 km-wide ice-dammed lake on the northern margin of Russell Glacier in a semidrained state in July 2014. (B): Grid coordinates are UTM 22N
