项目摘要

The analysis of sulphur isotopes in archaeological materials is a novel and potentially powerful tool for the reconstruction of ancient ecosystems, diets and environments. As with other stable isotope approaches, before sulphur isotope analysis can become routine in archaeological research there is clear need for hypothesis-driven research in areas including marine, freshwater and terrestrial foodwebs. The rich coastal zones of western Canada represent one such opportunity as the area includes all three of these ecosystems. Furthermore, archaeological evidence demonstrates hunter-gatherer populations exploited all three ecosystems throughout the Holocene, allowing modern and ancient environments to be directly compared. This project will centre around four main case studies which will all make significant contributions to our understanding of sulphur isotope systematics: These include reconstruction of marine mammal behavioural ecology using sulphur isotopes (first preliminary results are shown); a study of the diachronic changes of sulphur isotopic signatures in migratory fish species; an assessment of the interaction between sulphur isotopes of freshwater and terrestrial environments; and the reconstruction of an archaeological estuarine ecosystem through sulphur isotope analysis. The synthesis of this data will not only contribute greatly to stable isotope research, but will also result in a more comprehensive view of hunter-gatherer diets in the area, and the changing influence of the local environments of the subsistence strategies of contemporary human populations. This study will combine multiple disciplines (ecology, archaeology and anthropology) to increase our knowledge of hunter-gatherer societies with large implications for other important archaeological questions.

考古材料中硫同位素的分析是重建古代生态系统、饮食和环境的一种新的和潜在的有力工具。与其他稳定同位素方法一样，在硫同位素分析成为考古研究的常规方法之前，显然需要在海洋、淡水和陆地食物网等领域进行假设驱动的研究。加拿大西部丰富的沿海地区代表了这样一个机会，因为该地区包括所有这三个生态系统。此外，考古证据表明，狩猎采集人口在整个全新世都在利用这三个生态系统，从而可以直接比较现代和古代环境。该项目将围绕四个主要的案例研究，这些案例研究将对我们理解硫同位素系统学做出重要贡献：其中包括利用硫同位素重建海洋哺乳动物行为生态学（显示第一批初步结果）;研究洄游鱼类硫同位素特征的历时变化;评估淡水和陆地环境硫同位素之间的相互作用;以及通过硫同位素分析重建考古学意义上的河口生态系统。这些数据的综合不仅将大大有助于稳定同位素研究，而且还将导致对该地区狩猎采集者饮食的更全面的看法，以及当地环境对当代人类生存战略的不断变化的影响。这项研究将联合收割机多学科（生态学，考古学和人类学），以增加我们的狩猎采集社会的知识与其他重要的考古问题的重大影响。
