The Spermonde Archipelago, off the coast of southwest Sulawesi, consists of more than 100 small islands and hundreds of shallow-water reef areas. Most of the islands are bordered by coral reefs that grew in the past in response to paleo relative sea-level changes. Remnants of these reefs are preserved today in the form of fossil microatolls. In this study, we report the elevation, age, and paleo relative sea-level estimates derived from fossil microatolls surveyed in five islands of the Spermonde Archipelago. We describe 24 new sea-level index points, and we compare our dataset with both previously published proxies and with relative sea-level predictions from a set of 54 glacial isostatic adjustment (GIA) models, using different assumptions on both ice melting histories and mantle structure and viscosity. We use our new data and models to discuss Late Holocene (0–6 ka) relative sea-level changes in our study area and their implications in terms of modern relative sea-level estimates in the broader South and Southeast Asia region.

印度尼西亚望加锡海峡晚全新世（0â???? 6 ka）海平面变化

位于西南苏拉威西岛海岸的斯珀蒙德群岛，由100多个小岛和数百个浅水礁区组成。大多数岛屿都被珊瑚礁接壤，这些珊瑚礁过去是因古相对海平面变化而增长的。今天，这些礁石的残余物以化石微礁的形式保存。在这项研究中，我们报告了从在Spermonde群岛的五个岛上调查的化石微礁获得的海拔，年龄和古相对海平面估计值。我们描述了24个新的海平面指数，并使用冰融化历史和地幔的不同假设，将我们的数据集与以前发布的代理数据和来自一组54个冰川等静压调整（GIA）模型的相对海平面预测进行了比较。结构和粘度。
