This paper provides a summary of published sea-level archives representing the past position of sea level during the Last Interglacial sea-level highstand in the Bahamas, Turks and Caicos, and the eastern (Atlantic) coast of Florida, USA. These data were assembled as part of a community effort to build the World Atlas of Last Interglacial Shorelines (WALIS) database. Shallow marine deposits from this sea-level highstand are widespread across the region and are dominated by carbonate sedimentary features. In addition to depositional (constructional) sedimentary indicators of past sea-level position, there is also evidence of erosion, dissolution, and/or subaerial exposure in places that can place an upper limit on the position of sea level. The sea-level indicators that have been observed within this region and attributed to Marine Isotope Stage (MIS) 5e include corals, oolites, and other coastal sedimentary features.Here we compile a total of 50 relative sea-level indicators including 36 in the Bahamas, three in West Caicos, and a remaining 10 for the eastern seaboard of Florida. We have also compiled U-Th age data for 24 fossil corals and 56 oolite samples. While some of these archives have been dated using U-Th disequilibrium methods, amino acid racemization, or optically stimulated luminescence, other features have more uncertain ages that have been deduced in the context of regional mapping and stratigraphy. Sedimentary archives in this region that constrain the elevation of the past position of sea level are associated with uncertainties that range from a couple of decimeters to several meters. Across the Bahamas and on West Caicos, one of the observations that emerges from this compilation is that estimation of sea-level position in this region during Marine Isotope Stage 5e is complicated by widespread stratigraphic evidence for at least one sea-level oscillation. This evidence is defined by submarine features separated by erosion and subaerial exposure, meaning that there were likely multiple distinct peaks in sea level rather than just one. To this end, the timing of these individual sea-level indicators becomes important when compiling and comparing data across the region given that different archives may have formed during different sub-orbital peaks in sea level.

巴哈马、特克斯和凯科斯群岛以及美国佛罗里达州东海岸的末次间冰期（海洋同位素 5e 阶段）海平面指标汇编

本文概述了已发表的海平面档案，这些档案代表了巴哈马、特克斯和凯科斯群岛以及美国佛罗里达州东部（大西洋）海岸在末次间冰期海平面高位期间的海平面位置。这些数据是社区努力构建末次间冰期海岸线世界地图集 (WALIS) 数据库的一部分。这个海平面高位的浅海沉积物在该地区广泛分布，并以碳酸盐沉积特征为主。除了过去海平面位置的沉积（构造）沉积指标外，在可能对海平面位置设置上限的地方，还有侵蚀、溶解和/或地下暴露的证据。在该区域内观测到的海平面指标属于海洋同位素阶段 (MIS) 5e，包括珊瑚、鲕粒岩和其他沿海沉积特征。这里我们编制了总共 50 个相对海平面指标，其中巴哈马群岛有 36 个，三个在西凯科斯群岛，剩下的 10 个在佛罗里达州东海岸。我们还编制了 24 种珊瑚化石和 56 种鲕石样品的 U-Th 年龄数据。虽然其中一些档案已使用 U-Th 不平衡方法、氨基酸消旋化或光激发发光进行了年代测定，但其他特征具有更多不确定的年龄，这些年龄已在区域测绘和地层学的背景下推断出来。该地区的沉积档案限制了过去海平面位置的高程，其不确定性范围从几分米到几米不等。在整个巴哈马群岛和西凯科斯群岛，从该汇编中得出的观察结果之一是，在海洋同位素 5e 阶段期间对该地区海平面位置的估计由于至少有一次海平面振荡的广泛地层证据而变得复杂。这一证据是由被侵蚀和水下暴露分开的海底特征定义的，这意味着海平面上可能有多个不同的峰值，而不仅仅是一个。为此，鉴于在海平面的不同亚轨道峰值期间可能形成了不同的档案，因此在编译和比较整个区域的数据时，这些单独的海平面指标的时间安排变得很重要。该数据库可在 https://doi.org/10.5281/zenodo.5596898 找到（Dutton 等人，2021 年）。
