Abstract. During the 2014 GEOVIDE transect, seawater samples were collected for dissolved Pb and Pb isotope analysis. These samples provide a high-resolution "snapshot" of the source regions for the present Pb distribution in the North Atlantic Ocean. Some of these stations were previously occupied for Pb from as early as 1981, and we compare the 2014 data with these older data, some of which are reported here for the first time. Lead concentrations were highest in subsurface Mediterranean Water (MW) near the coast of Portugal, which agrees well with other recent observations by the US GEOTRACES program (Noble et al., 2015). The recently formed Labrador Sea Water (LSW) between Greenland and Nova Scotia is much lower in Pb concentration than the older LSW found in the West European Basin due to decreases in Pb emissions into the atmosphere during the past 20 years. Comparison of North Atlantic data from 1989 to 2014 shows decreasing Pb concentrations consistent with decreased anthropogenic inputs, active scavenging, and advection/convection. Although the isotopic composition of northern North Atlantic seawater appears more homogenous compared to previous decades, a clear spatiotemporal trend in isotope ratios is evident over the past 15 years and implies that small changes to atmospheric Pb emissions continue. Emissions data indicate that the relative proportions of US and European Pb sources to the ocean have been relatively uniform during the past 2 decades, while aerosol data may suggest a greater relative proportion of natural mineral Pb. Using our measurements in conjunction with emissions inventories, we support the findings of previous atmospheric analyses that a significant portion of the Pb deposited to the ocean in 2014 was natural, although it is obscured by the much greater solubility of anthropogenic aerosols over natural ones.

“…The water for metal analysis was filtered from the PVDF samplers over a 0.2-μm filter cartridge (Sartobran-300, Sartorius) under pressure (0.5 bar overpressure) of (inline prefiltered) nitrogen gas, whereas the samples for nutrients were unfiltered. Subsequently, the data were deemed intercalibrated by the GEOTRACES standards and intercalibration committee and are part of the GEOTRACES intermediate data product (Mawji et al, 2015;Schlitzer et al, 2018). These seawater samples were acidified to a concentration of 0.024 M hydrochloric acid, which results in a pH of 1.7 to 1.8 with Baseline® hydrochloric acid (Seastar Chemicals Inc.).…”

Dissolved zinc (Zn) has a nutrient‐type distribution in the ocean that more closely resembles the distribution of silicate (Si) than phosphate (PO4). However, Zn is a trace‐nutrient and mostly present in the organic fraction of phytoplankton rather than the siliceous frustule. It has been suggested the coupling of Zn and Si is caused by the strong depletion of nutrients in the Southern Ocean, possibly combined with scavenging of Zn. Here we assess the distribution of Zn and nutrients along the conduit of southward traveling waters of northern origin and northward traveling waters of Antarctic origin to unravel the influence of various water masses and local biogeochemical processes in the Atlantic Ocean. The distribution of Zn and Si is governed by mixing such that influence of remineralization is barely distinguishable, whereas the distribution of PO4 is influenced by both processes. The subsurface water masses that supply nutrients to the surface ocean are depleted in Zn. Indeed, the Southern Ocean water masses play a driving role, but remarkably, also subsurface water masses from northern high‐latitude origin are depleted in Zn. Both northern and southern high‐latitude waters have a relatively high Zn:PO4 uptake and remineralization ratio, implying it is Zn availability and not only chronic iron limitation that leads to increased Zn uptake in the high‐latitude regions. The limited supply of Zn to the surface Atlantic Ocean can explain the lack of an Atlantic Zn remineralization signal and indicates Zn might play a role in phytoplankton community composition and productivity.
