A dataset of stable barium isotopes in pore waters and sediments of the Pearl River Estuary

This dataset is based on an article entitled "stable barium isotope fractionation in pore waters of estuarine sediments", which includes:Table 1: Salinity, dissolved barium (Ba) concentrations, and their stable Ba isotopic composition (δ137Ba and δ138Ba) data for the bottom waters and pore waters of the Pearl River Estuary in January 2017.Table 2: Stable barium isotopic composition (δ137Ba and δ138Ba) data for various Ba carriers of selected sediment samples in the Pearl River Estuary in January 2017.Table 3: Dissolved nitrate (NO3-), manganese (Mn), iron (Fe), and sulfate (SO42-) concentration and barite saturation state (BSS) data for the pore waters of the Pearl River Estuary in January 2017.Table 4: Bulk barium (Ba), manganese (Mn), iron (Fe), and aluminum (Al) concentration data, Ba/Al, Mn/Al, and Fe/Al ratio data, and bulk total organic carbon (TOC) concentration data for the sedimentary solid phase of the Pearl River Estuary in January 2017.
