We present spatially highly resolved distributions of dissolved seawater rare earth element concentrations and neodymium isotopes along a transect in the central Arctic Ocean from FS Polarstern cruise PS94 (GEOTRACES GN04) in August-October 2015. Seawater samples were collected using Niskin bottles and filtered through AcroPak 500 filter cartridges (pore size 0.8/0.2 µm) directly from the Niskin bottles onboard
