Apparent marine radiocarbon ages are reported for the northern Indian Ocean region for the pre-nuclear period, based on measurements made in seven mollusk shells collected between 1930 and 1954. The conventional 14C ages of these shells range from 693 +/44 to 434 +/51 BP in the Arabian Sea and 511 +/34 to 408 +/51 BP in the Bay of Bengal. These ages correspond to mean Delta-R correction values of 163 +/30 yr for the northern Arabian Sea, 11 +/35 yr for the eastern Bay of Bengal (Andaman Sea) and 32 +/20 yr for the southern Bay of Bengal. Contrasting reservoir ages for these two basins are most likely due to differences in their thermocline ventilation rates.Type
