【 摘 要 】

In this paper we present a high resolution palaeo coastline model for the isolated limestone massif of Tra = ng An, Ninh B & igrave;nh province, Vietnam. The archaeological and palaeoecological record here comprise rich archives of human activity set within a landscape that was cyclically transformed between inland and archipelagic states under the influence of past sea level changes. These records have become informative proxies in the study of current sea level rise. Well-preserved notches along the vertical limestone cliffs within the study property reveal several phases of prolonged stable sea levels that likely pertain to the Mid-Holocene marine transgression 8 ka BP to 4 ka BP and allow for detailed coastline reconstructions for parts of the Red River Delta (RRD). The resulting coastline model facilitates a closer look at past human responses to landscape and environmental changes at local and individual site-level, which improves our understanding of past human adaptations to climate-change induced sea level rise. These data also stand to inform current coastal vulnerability assessments and climate change response models. (c) 2021 Elsevier Ltd. All rights reserved.
