Water-stable isotope (d18O, dD), sodium (23Na), and magnesium (24Mg) Continuous Flow Analysis data for the Palmer ice core, Palmer Land, Antarctic Peninsula, 1621-2011 C.E.

Here we provide the Palmer ice core Water-stable isotope (d18O, dD), sodium (23Na), and magnesium (24Mg) palaeo archives. The Palmer drill site (73.86 S, 65.46 W, 1897 m a.s.l.) is located on the southern part of the Antarctic Peninsula, Palmer Land. The core, firn and ice, were drilled in December 2012 to a depth of 133 m below the snow surface. The Palmer ice core covers 391 years, 1621-2011 C.E. The data were measured on the British Antarctic Survey Continuous Flow Analysis system in Cambridge, UK. Data is given both on depth and temporal (annual means) scales. The d18O and dD records were measured on a CFA laser spectroscopy system and the 23Na and 24Mg data were measured on the CFA ICP-MS setup. The ice core drilling and analysis were funded by the British Antarctic Survey, Natural Environment Research Council (NERC, Cambridge, UK), part of UK research and innovation and NERC grant NE/J020710/1. The Palmer analysis was funded by Haus der Kulturen der Welt (HKW, Berlin, Germany), in collaboration with the Anthropocene working group (AWG).
