A database of radiogenic Sr–Nd isotopes at the “three poles”

open access: yesEarth System Science Data, 2022
Abstract. The radiogenic isotope compositions of strontium (Sr) and neodymium (Nd) on the surface of the Earth are powerful tools for tracing dust sources and sinks on the Earth's surface. To differentiate between the spatial variabilities in eolian dust sources in key cryospheric regions at the three poles (the Arctic; Antarctica; and the “third pole”,

Glacial–interglacial Nd isotope variability of North Atlantic Deep Water modulated by North American ice sheet

open access: yesNature Communications, 2019
The Nd isotope composition of seawater has been used to reconstruct past changes in the various contributions of different water masses to the deep ocean, with the isotope signatures of endmember water masses generally assumed to have been stable during ...
