Abstract:

The Neodymium (Nd) isotopic signature (εNd) has been widely used as a proxy to reconstruct past ocean circulation. Recently it has been increasingly questioned which archives can be reliably used to extract authigenic εNd used for the reconstruction of past ocean circulation and under which environmental conditions bottom seawater εNd are altered and the original water mass signature is overprinted. Pore waters of marine sediments are the key environment in which early diagenetic exchange processes between seawater-derived Nd and terrigenous solid phases take place. This dataset contains rare earth element and yttrium (REY) and manganese (Mn) concentrations of bottom seawater from the abyssal Atlantic Ocean.

Samples were collected during cruise MSM96 in 2020. Seawater samples were taken with NISKIN bottles attached to a CTD water sampling carousel. Samples were filtered using 0.8/0.2 µm Acropak capsule filters for the dissolved fraction (<0.2 µm), and subsequently through either 0.015 µm nuclepore membrane filters (Whatman; under gas pressure) for the soluble (<0.015 µm) fraction or ultrafiltered using a Millipore Pellicon 2 tangential flow ultrafiltration system with a 10 kDa nominal molecular weight cutoff (truly dissolved fraction <10 kDa). Samples were preserved by acidification to ~ pH 1.8 with concentrated ultrapure HCl.

REY and Mn were preconcentrated offline using a seaFAST (Elemental Scientific Inc., Nebraska, USA) with a 10 mL sample loop and using a NOBIAS PA-1 resin column. Samples were spiked with 100 ppt Tm and In to monitor yields and all REY were Tm corrected at the end of the data evaluation. Correction was usually within 5-15%. Preconcentrated samples were measured on a Thermo Fisher Element HR-ICP-MS (GEOMAR, Kiel) coupled to a CETAC Aridus 2 desolvating nebulizer for increased sensitivity and decreased oxide formation.
