| Particles play an important role in the marine biogeochemical cycling of iron, an essential micronutrient. Particles of biogenic, lithogenic and authigenic origin can act as sources or sinks of dissolved iron and therefore influence its distribution and availability to phytoplankton. However, not all particulate Fe (pFe) is readily accessible to phytoplankton and various treatments are used to estimate the bioavailable, or labile fraction of pFe. Here we report concentration and iron stable isotope data for the “ligand-leachable” fraction of pFe, following the application of a pH 8 oxalate-EDTA leach to 0.8–51 μm-sized particles collected during the US GEOTRACES East Pacific Zonal Transect (GP16). Across the GP16 section, we identified two regions of high... |
