A standardized database of Last interglacial (MIS 5e) sea-level indicators in Southeast Asia

Abstract. Marine Isotope Stage 5e (the Last Interglacial, LIG) represents a process analogue for a warmer world expected for the near future. Analysis of LIG relative sea level (RSL) proxies helps in constraining both regional and global drivers of sea-level change. In Southeast Asia, several studies have reported elevation and age information on LIG RSL proxies, such as fossil coral reef terraces or tidal notches, but a standardized database of such data was hitherto missing. In this paper, we produced such sea-level database using the framework of the World Atlas of Last Interglacial Shorelines (WALIS, https://warmcoasts.eu/world-atlas.html ). Overall, we screened and reviewed 14 studies on LIG sea-level indicators in Southeast Asia, from which we report 43 unique RSL proxies (42 coral reef terraces and one tidal notch), that were correlated to 134 dated samples. The database compiled in this study (Maxwell et al., 2021) is available at https://doi.org/10.5281/zenodo.4681325 .
