Abstract:
The dataset contains the concentrations of rare earth elements (REEs) in coastal surface seawater, the Caeté River, intertidal creek seawater, porewaters, and the Fe-Mn oxyhydroxide fraction of sediments in combination with the isotope compositions of Nd and Hf of coastal seawater, porewater and coastal sediment. Coastal seawater and sediment samples were obtained in April–May 2018 during RV Meteor cruise M147, which was official process study Gapr11 of the international GEOTRACES program.
