Neodymium, strontium and lead isotope data from onshore and marine tills in Ross Sea and vicinity, Antarctica

This data set includes neodymium, strontium and lead isotope data from the < 63 micron size fraction from both onshore and marine surface tills from the Ross Sea and vicinity. From western Antarctica, onshore tills were analyzed associated with the Whillans, Kamb and MacAyeal ice streams. In eastern Antarctica, onshore tills from the Beardmore and Darwin glaciers were analyzed, and from Mt. Archenar and the Allan Hills. Marine tills from the RISP cores and from numerous cores throughout the Ross Sea were analyzed.
