Changes in relative sea level (RSL) are the net effect of contributions from eustatic, isostatic, tectonic and other local factors, such as subsidence due to sediment compaction1. Holocene sea-level reconstructions are needed to constrain both vertical land movements and geophysical models of Glacial Isostatic Adjustment (GIA), that are in turn used to correct sea level measurements obtained with instrumental measures, such as tide gauges. Therefore, regional Holocene RSL datasets, surveyed following standardized protocols, represent a long-term baseline against which to assess changes in sea level during the past century and to evaluate sea-level changes in the 21st century at local and regional scale. While accurate Holocene RSL datasets are available for some areas RSL reconstructions for a region highly vulnerable to future sea level rise such as Southeast Asia are still limited, fragmentary and there are still problems associated with the correct interpretation of sea-level indicators and their relationship to sea level, and with the quality of age determinations.
In this topic, we work to answer questions related to the use of different kinds of RSL markers and to the reconstruction of Holocene sea level histories.
