Dissolved rare earth element concentrations and neodymium isotope compositions in the central Arctic Ocean during FS Polarstern PS94 (GEOTRACES GN04)

Abstract

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
