(Table 2) Radiocarbon dating on selected surface sediments from the eastern tropical Indian Oceana@en

Radiocarbon ages are converted to calendar ages using Marine 09 calibration [Hughen et al., 2004] of CALIB 6.0 software. Samples were measured at the Keck Carbon Cycle Accelerator Mass Spectrometry Laboratory, University of California, Irvine (UCI), and at the National Ocean Sciences Accelerator Mass Spectrometry Facility, Woods Hole (OS), respectively. SB: Simeulue Basin; NB: Nias Basin; NMB: Northern Mentawai Basin; SMB: Southern Mentawai Basin; JB: Java Basin; LB: Lombok Basin; SS: Savu Sea. Note that radiocarbon ages are converted to calendar ages assuming no deviation from the global ocean carbon reservoir of 400 years.
