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. Vertical profile from 29.6-719 m (UK GEOTRACES 40° S cruise). Coordinates from Table 3.
