The application of sedaDNA within landscape archaeology is a largely an untested method. The current application provides an opportunity to consider sedaDNA methodology, against a series of proxy palaeoenvironmental methods, within a strategic and high profile project. The Stonehenge Hidden Landscapes Project undertook one of the largest terrestrial multi-sensor, archaeo-geophysical surveys in Britain. Covering c. 10 square kilometres around one of Britain's iconic archaeological monuments, this survey has generated thousands of potential archaeologic features and these have been described in a series of articles and are currently being prepared for a comprehensive publication. Whilst most features identified are interpretable or conform to known comparators several exceptional features remain unexplained and are, potentially of considerable importance. These include a series of massive geophysical anomalies related to one of the largest monuments in the region - the Durrington Wall Henge. Initially interpreted as modern dewponds, a recent excavation identified 3 similar anomalies and interpreted these as, potentially, natural sinkholes with prehistoric fills. Further research identified no fewer than 15 similar features with a distribution essentially circling the later Neolithic Henge. These anomalies, and their suggestive distribution, were of sufficient interest to mount a separate exploratory campaign of high-resolution survey and coring proving that the magnetic anomalies represent pits 18 metres diameter and up to 4.8 metres deep. Coring also suggests that the position of some of these monuments on the Avon river terraces may provide conditions to test the boundaries of sedaDNA applications, whilst also seeking to assess the function of these peculiar, massive archaeological features Methodology: The proposed programme of work will enhance and extend our knowledge of these massive features and will include re-survey of all available features and coring across a series of features for palaeoenvironmental study and a broader dating programme. It is also intended to work within the landscape, and the Avon river terraces specifically, to provide a broader context to data from archaeological features. The PhD candidate will retrieve sedaDNA from samples of cores to assess taphonomy in the context of the monuments, and based on these findings determine to what extent sedaDNA can reveal about them in terms of their use and the depositional environment. Ancient DNA techniques for sedaDNA developed at Warwick will be followed using dedicated ancient DNA facilities and a world class research group. Next generation sequencing will be applied, combined with bioinformatic protocols to analyse data.

sedaDNA在景观考古学中的应用在很大程度上是一种未经测试的方法。目前的应用程序提供了一个机会，考虑sedaDNA方法，对一系列代理古环境的方法，在一个战略和高姿态的项目。巨石阵隐藏景观项目进行了英国最大的陆地多传感器考古地球物理调查之一。覆盖C。在英国标志性的考古遗址之一周围10平方公里的范围内，这项调查产生了数千个潜在的考古特征，这些特征已在一系列文章中描述，目前正在准备全面出版。虽然大多数确定的功能是可解释的或符合已知的比较器几个特殊的功能仍然无法解释，是，潜在的相当重要的。其中包括一系列与该地区最大的纪念碑之一--杜灵顿长城有关的大规模地球物理异常。最初被解释为现代的露水池，最近的一次挖掘发现了3个类似的异常现象，并将其解释为可能是史前填充的天然天坑。进一步的研究发现了不少于15个类似的特征，其分布基本上围绕着后来的新石器时代巨石阵。这些异常及其暗示性的分布引起了足够的兴趣，足以单独开展高分辨率测量和取芯的勘探活动，证明磁性异常代表直径18米、深4.8米的坑。取芯还表明，埃文河阶地上的一些古迹的位置可能为测试sedaDNA应用的边界提供条件，同时也寻求评估这些独特的，大规模的考古特征的功能。拟议的工作计划将加强和扩大我们对这些巨大特征的了解，并将包括重新对所有现有特征进行调查，并对一系列特征取芯，以进行古环境研究和更广泛的测年方案。它还打算在景观中工作，特别是雅芳河阶地，为考古特征的数据提供更广泛的背景。博士候选人将从岩心样本中检索sedaDNA，以评估古迹背景下的埋藏学，并根据这些发现确定sedaDNA在多大程度上可以揭示它们的使用和沉积环境。在沃里克开发的用于sedaDNA的古代DNA技术将使用专门的古代DNA设施和世界级的研究小组。将应用下一代测序，结合生物信息学协议来分析数据。
