Archaeological evaluation (five trial-trenches) carried out as specified in the project brief and wsi. A five-trench archaeological evaluation was carried out on land west and east of Michaelstowe Old House, Ramsey Road, Ramsey, Essex, in advance of the construction of new dwellings. The site lies within the vicinity of the medieval settlement of Ramsey, close to the medieval buildings of Michaelstowe Hall and St Michael's Church. Excavations revealed post-medieval structural features in the southeastern corner of the development site, consisting of a wall foundation of late 18th to early 19th century date, and a drainage sump, brick drain and cobbled surface dating from c 1850 onwards. Other features consisted of post-medieval and undated pits, a post-medieval/modern grubbed-out hedgerow, modern garden features and undated tree-throws.

Stable isotope analysis has been utilized in archaeology since the 1970s, yet standardized protocols for terminology, sampling, pretreatment evaluation, calibration, quality assurance and control, data presentation, and graphical or statistical treatment still remain lacking in archaeological applications. Here, we present recommendations and requirements for each of these in the archaeological context of: bulk stable carbon and nitrogen isotope analysis of organics; bulk stable carbon and oxygen isotope analysis of carbonates; single compound stable carbon and nitrogen isotope analysis on amino acids in collagen and keratin; and single compound stable carbon and hydrogen isotope analysis on fatty acids. The protocols are based on recommendations from the Commission on Isotopic Abundances and Atomic Weights of the International Union of Pure and Applied Chemistry (IUPAC) as well as an expanding geochemical and archaeological science experimental literature. We hope that this will provide a useful future reference for authors and reviewers engaging with the growing number of stable isotope applications and datasets in archaeology.

Abandoned river channels may provide rich primary sources of palaeoenvironmental and cultural information elucidating landscape evolution, climate change, vegetation history and human impact, especially since the beginning of the Holocene epoch. However, although potentially an important resource, palaeochannels are not often recorded systematically and only rarely enjoy robust statutory protection (in the UK as Sites of Special Scientific Interest). In consequence, it is challenging to mitigate and manage this important geoarchaeological resource effectively within the UK planning framework. Whilst palaeochannels have long been recognised on aerial photographs and historic maps, the advent of airborne laser scanning (Lidar) and other remote-sensing technologies has provided a hitherto unforeseen opportunity to record such landforms and related features at a catchment scale. This paper provides a case study from the Nottinghamshire reach of the Trent Valley, where a desk-based methodology that is now being extended across the entire catchment has been developed for recording, geospatially locating and defining the attributes of observed palaeochannels. After outlining the methodology, we consider how this approach to resource management can aid archaeological research and future heritage management, especially in the light of predicted climate and environmental change.

ABSTRACTMesolithic settlement sites preserved on the north‐east coast of England and in south‐east Scotland drive questions about the relationship between early human settlement and the Holocene palaeogeography of ‘Doggerland’. Palaeogeographical reconstructions before 8000 years ago have been restricted by a lack of sea‐level index points and particularly by sparse nearshore geophysical and geological datasets required for such reconstructions. This paper presents new high‐resolution geophysical survey data from Northumberland's nearshore ‘white ribbon’ which provide a foundation for more accurate palaeogeographical reconstructions within which early prehistoric settlement sites can be more readily understood. High‐resolution bathymetry data collected in the nearshore adjacent to the Mesolithic house site at Howick are integrated with coastal LiDAR, seismic, geological and archaeological datasets to underpin palaeogeographical reconstructions. The reconstructions illustrate changing coastal landscapes during Early Holocene sea‐level rise. The data and interpretations provide a ‘source‐to‐sea’ context for understanding the archaeology at important sites such as Howick and Low Hauxley. Furthermore, they provide a basis for enhancing management of at‐risk coastal prehistoric archaeology and a framework to prospect for and protect further vulnerable nearshore archaeological heritage.

Examples of wetland deposits can be found across the globe and are known for preserving organic archaeological and environmental remains that are vitally important to our understanding of past human-environment interactions. The Mesolithic site of Star Carr (Yorkshire, United Kingdom) represents one of the most influential archives of human response to the changing climate at the end of the last glacial in Northern Europe. A hallmark of the site since its discovery in 1948 has been the exceptional preservation of its organic remains. Disturbingly, recent excavations have suggested that the geochemistry of the site is no longer conducive to such remarkable survival of organic archaeological and environmental materials. Microcosm (laboratory-based) burial experiments have been undertaken, alongside analysis of artifacts excavated from the site, to assess the effect of these geochemical changes on the remaining archaeological material. By applying a suite of macroscopic and molecular analyses, we demonstrate that the geochemical changes at Star Carr are contributing to the inexorable and rapid loss of valuable archaeological and paleoenvironmental information. Our findings have global implications for other wetland sites, particularly archaeological sites preserved in situ.
