Fig. 1

Tectonically driven changes in site locations are shown with symbol size (see legend). Filled circles indicate cores with FB-δ15N data, from this study (872/516) and from Kast et al.18 (1209/1263), and open circles indicate cores with foraminiferal δ18O data discussed in the text37,41 (and references therein). Dissolved O2 concentrations (in μmol kg−1) are shown in colour.
