Abstract The Channel Islands of California have received much attention from researchers, in part, due to the long occupation history of the islands that spans at least 13,000 years. The Northern Channel Islands have played an important role in our understanding of early coastal adaptations and development of complexity among maritime adapted peoples; however, this is only part of the picture. The Southern Channel Islands, located approximately 90 km south of the Northern Channel Islands, have a similar occupational history to their northern counterparts, but exist in a very different environmental and geographic context. Occupants on each island would have faced marine and terrestrial environments that could be vastly different based on issues such as fluctuating sea temperatures, fresh water accessibility, and plant, animal, and marine shell seasonality. The coastal adaptations along all the Channel Islands reflected these differences. Understanding variation on the Channel Islands archipelago can be realized by comparing and contrasting multiple types of environmental and material data from trans-Holocene sites, archaeological deposits that present continuous data sequences over a wide time span of the Holocene. One such site from San Clemente Island in the southern portion of the archipelago is Eel Point. Previous excavations at this site resulted in a rich array of cultural material; however, recent research has shown major portions of the collections have not yet been processed, are unanalyzed, or are under-analyzed. Specifically the groundstone and archaeobotanical assemblages have not been comprehensively analyzed or reported on, but are integral to understanding not only subsistence strategies, but also technological development and island paleo and historical ecology. These data form the basis for an inter-island comparative approach to understand long-term human-environmental interactions and impacts to ancient ecosystems on the Channel Islands archipelago. This study focuses on leveraging these under-analyzed and unanalyzed data to present on the variation in adaptions on the archipelago and to demonstrate the relevance of multi-island studies for considering the cultural impacts of climatic change in Mediterranean environments.

评估加利福尼亚海峡群岛海洋发展的跨全新世方法：来自圣克莱门特岛 Eel Point 的案例研究

摘要 加利福尼亚海峡群岛受到了研究人员的广泛关注，部分原因是这些岛屿至少有 13,000 年的悠久占领历史。北海峡群岛在我们了解早期沿海适应和海洋适应人群的复杂性发展方面发挥了重要作用；然而，这只是画面的一部分。南海峡群岛位于北海峡群岛以南约 90 公里处，与北部地区有着相似的职业历史，但存在于截然不同的环境和地理环境中。每个岛上的居民都会面临海洋和陆地环境，这些环境可能因海水温度波动、淡水可及性以及植物、动物、和海洋贝壳季节性。沿所有海峡群岛的海岸适应反映了这些差异。可以通过比较和对比来自跨全新世遗址的多种类型的环境和材料数据来了解海峡群岛的变化，考古沉积在全新世的很长一段时间内呈现连续的数据序列。来自群岛南部圣克莱门特岛的一个这样的地点是鳗鱼角。先前在该地点的发掘产生了丰富的文化材料。然而，最近的研究表明，大部分藏品尚未处理、未经分析或分析不足。具体而言，尚未对基石和古植物组合进行全面分析或报告，但对于理解生存战略、技术发展以及岛屿古和历史生态来说，这些都是不可或缺的。这些数据构成了岛屿间比较方法的基础，以了解长期人类与环境的相互作用以及对海峡群岛群岛古代生态系统的影响。本研究侧重于利用这些未充分分析和未分析的数据来展示群岛适应的变化，并证明多岛研究在考虑地中海环境气候变化的文化影响方面的相关性。这些数据构成了岛屿间比较方法的基础，以了解长期人类与环境的相互作用以及对海峡群岛群岛古代生态系统的影响。本研究侧重于利用这些未充分分析和未分析的数据来展示群岛适应的变化，并证明多岛研究在考虑地中海环境气候变化的文化影响方面的相关性。这些数据构成了岛屿间比较方法的基础，以了解长期人类与环境的相互作用以及对海峡群岛群岛古代生态系统的影响。本研究侧重于利用这些未充分分析和未分析的数据来展示群岛适应的变化，并证明多岛研究在考虑地中海环境气候变化的文化影响方面的相关性。
