SummaryThe three long barrows described in this report were totally excavated between 1959 and 1967. They have been presented in a single report because they had several features in common: they were in close proximity; they were built as single phase monuments; two conformed to a common specification which required elaborate internal structures; and they produced no evidence of funerary function or intent. There are four sections: I. The Horslip (or Windmill Hill) Long Barrow (P. A.). II. The Beckhampton Road Long Barrow (I.F.S.). III. The South Street Long Barrow (J.G.E.). The fourth section (IV) deals with the environmental history of the area as revealed in the long barrow soils and sediments (J.G.E.).

Abstract. Climate change increases the occurrence and severity of droughts due to increasing temperatures, altered circulation patterns, and reduced snow occurrence. While Europe has suffered from drought events in the last decade unlike ever seen since the beginning of weather recordings, harmonized long-term datasets across the continent are needed to monitor change and support predictions. Here we present soil moisture data from 66 cosmic-ray neutron sensors (CRNSs) in Europe (COSMOS-Europe for short) covering recent drought events. The CRNS sites are distributed across Europe and cover all major land use types and climate zones in Europe. The raw neutron count data from the CRNS stations were provided by 24 research institutions and processed using state-of-the-art methods. The harmonized processing included correction of the raw neutron counts and a harmonized methodology for the conversion into soil moisture based on available in situ information. In addition, the uncertainty estimate is provided with the dataset, information that is particularly useful for remote sensing and modeling applications. This paper presents the current spatiotemporal coverage of CRNS stations in Europe and describes the protocols for data processing from raw measurements to consistent soil moisture products. The data of the presented COSMOS-Europe network open up a manifold of potential applications for environmental research, such as remote sensing data validation, trend analysis, or model assimilation. The dataset could be of particular importance for the analysis of extreme climatic events at the continental scale. Due its timely relevance in the scope of climate change in the recent years, we demonstrate this potential application with a brief analysis on the spatiotemporal soil moisture variability. The dataset, entitled “Dataset of COSMOS-Europe: A European network of Cosmic-Ray Neutron Soil Moisture Sensors”, is shared via Forschungszentrum Jülich: https://doi.org/10.34731/x9s3-kr48 (Bogena and Ney, 2021).

The excavation of the earthwork and part of the interior of a C-shaped enclosure in south Norfolk produced evidence of a Neolithic occupation from the mid fourth to the late third millennium B.C. The earthwork was constructed at the end of the third millennium B.C. and palaeobotanical analyses of the fossil soil beneath it produced information concerning the environment of the time. Quantities of pot-sherds and stone tools were recorded from the earthwork and from clusters of pits, and a study of grain impressions on the pottery has given some indication of the crops cultivated in the third millennium B.C. in East Anglia. The report is concluded with a discussion of a system of fossil ice-wedge casts uncovered during the excavation and their relevance to archaeological investigations.
