A 2500-YEAR SEA LEVEL RECORD FROM PHRA THONG ISLAND, THAILAND

Abstract

Temporally changing coastline configurations and local sea-level changes pose a considerable threat to coastal communities and infrastructure. However, regional sea-level (RSL) histories spanning the last 3000 years have not been widely studied in Southeast Asia, even though the region shows significantly different RSL records from place to place (Horton et al., 2005). This period is crucial for understanding sea-level changes from pre-industrial time. Here, we investigate the record of past sea-level(s) preserved within the stratigraphy of the beach ridge system of Phra Thong Island (PTI), Thailand.
