Station of de Souza et al. (2012). Below 2000 m, Atlantic δ30Si results from quasi-conservative mixing between NADW precursors (+1.7 to +1.85 ‰, Si-poor) and AABW (about +1.2 ‰, Si-rich); the contrast arises from diatom Si utilisation in the Southern Ocean. Water depth 2710 m; coordinates from Table 1.
