Abstract: In this study, we report seawater dissolved zinc (Zn) concentration and isotope composition (δ 66 Zn) from the GEOTRACES GA01 (GEOVIDE) section in the North Atlantic. Across the transect, three subsets of samples stand out due to their isotopically light signature: those close to the Reykjanes Ridge, those close to the sediments, and those, pervasively, in the upper ocean. Similar to observations at other locations, the hydrothermal vent of the Reykjanes Ridge is responsible for the isotopically light Zn compo… Show more

In the surface, while heavy δ 66 Zn isotope compositions have been observed, the upper water column for Zn is often isotopically light or, in the Southern Ocean and North Pacific, only very slightly fractionated towards heavier values (Conway & John, 2014b;Zhao et al, 2014;Samanta et al, 2017;Takano et al, 2017;Wang et al, 2019a;Sieber et al, 2020;Vance et al, 2019;Liao et al, 2020;Lemaitre et al, 2020).…”
