|a Whether eustatic sea-level rise through the Holocene has been
punctuated or continuous has remained controversial for almost
two decades. Resolving this debate has implications for predicting
future responses of remaining ice sheets to climate change and also
for understanding the drivers of human settlement and dispersal patterns
through prehistory. Here we present a sea-level curve for the past
8900 yr from Singapore, a tectonically stable location remote from iceloading
effects. We also present critical and unique sedimentation rate,
organic 13C, and foraminiferal 13C proxy records of sea-level change
derived from a shallow-marine sediment core from the same area over
the same time interval. The sea-level curve, corroborated by the independent
proxy records, suggests rapid rise at a rate of 1.8 m/100 yr
until 8100 cal (calibrated) yr B.P., a near cessation in the rate of sealevel
rise between 7800 and 7400 cal yr B.P., followed by a renewed rise
of 4–5 m that was complete by 6500 cal yr B.P. We suggest that this
period of relatively stable sea level during the early to mid-Holocene
enabled modern deltas to advance, providing a highly productive environment
for the establishment of coastal sedentary agriculture. Periods
of rapid sea-level rise before and after may have catalyzed signifi -
cant postglacial episodes of human dispersal in coastal regions. |
