Relative sea-level (RSL) records from far-field regions distal from ice sheets remain poorly understood, particularly in the early Holocene. Here, we extended the Holocene RSL data from Singapore by producing early Holocene sea-level index points (SLIPs) and limiting dates from a new ~40 m sediment core. We merged new and published RSL data to construct a standardized Singapore RSL database consisting of 88 SLIPs and limiting data. In the early Holocene, RSL rose rapidly from −21.0 to −0.7 m from ~9500 to 7000 cal. yrs. BP. Thereafter, the rate of RSL rise decelerated, reaching a mid-Holocene highstand of 4.0 ± 4.5 m at 5100 cal. yrs. BP, before falling to its present level. There is no evidence of any inflections in RSL when the full uncertainty of SLIPs is considered. When combined with other standardized data from the Malay-Thai Peninsula, our results also show substantial misfits between regional RSL reconstructions and glacial isostatic adjustment (GIA) model predictions in the rate of early Holocene RSL rise, the timing of the mid-Holocene highstand and the nature of late-Holocene RSL fall towards the present. It is presently unknown whether these misfits are caused by regional processes, such as subsidence of the continental shelf, or inaccurate parameters used in the GIA model.

来自冰盖远端远场区域的相对海平面 (RSL) 记录仍然知之甚少，尤其是在全新世早期。在这里，我们通过生成早期全新世海平面指数点 (SLIP) 并限制新的 ~40 m 沉积物核心的日期，扩展了来自新加坡的全新世 RSL 数据。我们合并了新的和已发布的 RSL 数据，以构建一个由 88 个 SLIP 和限制数据组成的标准化新加坡 RSL 数据库。在全新世早期，RSL 从~9500 到 7000 cal 从 -21.0 迅速上升到 -0.7 m。年 BP。此后，RSL 上升速度减慢，在 5100 卡路里达到 4.0 ± 4.5 m 的全新世中期高位。年 BP，在下降到目前的水平之前。当考虑 SLIP 的完全不确定性时，没有证据表明 RSL 有任何变化。当与来自马来-泰国半岛的其他标准化数据相结合时，我们的结果还表明，区域 RSL 重建和冰川均衡调整 (GIA) 模型预测在早期全新世 RSL 上升率、中期全新世高位的时间和晚全新世 RSL 的性质下降方面存在严重失配。目前尚不清楚这些不匹配是否由区域过程（例如大陆架下沉）或 GIA 模型中使用的不准确参数引起。
