Radiocarbon (14C) has been instrumental in clarifying how people came to inhabit the expanse of Pacific Oceania, now supporting an “incremental growth model” that shows a number of long-distance sea-crossing migrations over the last few millennia. A crucial step in this narrative involved the initial settlement of the remote-distance Oceanic region, in the case of the Mariana Islands around 1500 BC. The Marianas case can be demonstrated through delineation of stratigraphic layers, dating of individual points or features within those layers, redundant dating of samples in secure contexts, localized and taxon-specific corrections for marine samples, and cross-constraining dating of superimposed layer sequences. Based on the technical and methodological lessons from the Marianas example, the further steps of the incremental growth model will continue to be refined across Pacific Oceania. Many of these issues may be relevant for broader research of ancient settlement horizons in other regions.

大洋洲的居民：确定公元前 1500 年马里亚纳群岛的最初定居地界

放射性碳 (14C) 有助于阐明人们是如何在广阔的太平洋地区居住的，现在支持“增量增长模型”，该模型显示了过去几千年中的一些长途跨海迁徙。这个叙述中的一个关键步骤涉及到遥远的海洋地区的初步定居，例如公元前 1500 年左右的马里亚纳群岛。Marianas 案例可以通过地层的划分、这些层中单个点或特征的测年、安全环境中样本的冗余测年、海洋样本的局部和特定分类校正以及叠加层序列的交叉约束测年来证明。基于 Mariana 示例中的技术和方法论教训，增量增长模式的进一步步骤将在整个太平洋地区继续完善。其中许多问题可能与其他地区古代聚落视野的更广泛研究有关。
