Seventy-nine Antarctic ice core snow accumulation records were collected as part of a collaborative project led by the PAGES Antarctica 2k working group. These records were normalized based on a reference period (1960-1990) and then grouped into seven geographical regions. The regions are: East Antarctica, Wilkes Land Coast, Weddell Sea Coast, Antarctic Peninsula, West Antarctic Ice Sheet, Victoria Land, and Dronning Maud Land. The normalized records from each region were averaged to create regional composites. For a detailed description of the data and methods used, refer to Thomas et al., 2017.
