Changes in intermediate and deep ocean circulation likely played a significant role in global carbon cycling and meridional heat/moisture transport during the middle Miocene climate transition (~14 Ma). High-resolution middle Miocene (16-13 Ma) benthic foraminifer stable isotope records from the South China Sea reveal a reorganization of regional bottom waters, which preceded the globally recognized middle Miocene ~1 per mil d18O increase (13.8 Ma) by 100,000 years. An observed reversal of the benthic foraminifera d13C gradient between ODP Sites 1146 (2092 m) and 1148 (3294 m; 13.9–13.5 Ma) is interpreted to reflect an increase in the southward flux of low d13C deep (> 2000 m) Pacific Ocean waters (Flower and Kennett, 1993, doi:10.1029/93PA02196; Shevenell and Kennett, 2004).
