Late Holocene Sr-Nd isotope and REE data from the Siple Dome ice core, Antarctica ...
Compositions of mineral dust in ice cores serve as tracers of paleo-atmospheric circulation patterns, providing linkages between sources and sinks. To determine the source(s) of dust to Siple Dome, Antarctica, we measured Sr-Nd isotope ratios and REE concentrations on late Holocene samples (~1030-18...
