Malay Thai Peninsula

Malay Thai Peninsula

The sea-level database (81 index points and 12 limiting data) from the Malay-Thai Peninsula reveal an upward trend of Holocene relative sea level from a minimum of -22 m at 9.7 – 9.2 ka to a mid-Holocene high stand of 4.8 – 4.4 ka, which equates to a rise of c. 5.5 mm/yr. The sea-level fall from the high stand is steady at c. -1.1 mm/yr. Geophysical modelling shows that hydro-isostasy contributes a significant spatial variation to the sea-level signal between some site locations (3-4 m during the mid-Holocene), indicating that it is not correct to construct a single relative sea-level history for the Malay-Thai Peninsula.
