Oxic open-ocean seawater analysed by Owens et al. (2017): 41 South Atlantic samples from -6.3 to -5.8, mean -6.0 ± 0.3 (2 SD) and 11.4 ± 2.1 pg/g Tl, with no variation with depth or water mass, like the Pacific and the Arctic: the open ocean is homogeneous for Tl isotopes. SAFe D1 intercalibration sample, used as the consistency standard for seawater; depth given as 0 in Table 3; Tl and isotopes identical to South Atlantic waters, with no contamination despite the iron issues reported for this material. Coordinates from Table 3.
