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

Abstract. The radiogenic isotope compositions of strontium (Sr) and neodymium (Nd) on the surface Earth are powerful tools for tracing dust sources sinks Earth's surface. To differentiate between spatial variabilities in eolian key cryospheric regions at three poles (the Arctic; Antarctica; “third pole”, covering high mountainous area Asia), a dataset Sr–Nd isotopic from extremely cold or arid terrestrial environments was compiled, similar to method Blanchet (2019). database includes Holocene Quaternary snow, ice, sand, soil (loess), sediment, rock samples based 90 different references our own measurement data, with total 1989 data points, comprising 206 points grain sizes 212 fraction measurements. There 485 third pole, 727 Arctic, 777 Antarctica. sampling methods these introduced. For each geographical coordinates other information provided. main scientific purpose this is provide collective documentation measurements, which will be useful determining transport pathways rivers, oceans near as well investigate whether multiple present poles. This provides exhaustive detailed signatures during specific time intervals period, understanding sediments available National Tibetan Plateau Data Center (https://doi.org/10.11888/Cryos.tpdc.272100, Du, 2022).
