Palaeoenvironmental Research

Introduction Information on the nature, timing and rates of past environmental change provides a valuable long term perspective for understanding current and future impacts of climate change. Physical, chemical and biological analysis of sedimentary archives help us to build up a picture of both regional climatic variability and local environmental change. The CHERISH project is focusing on sediment sequences which have the potential to provide records of past storm activity, extending back over thousands of years, such as coastal peat bogs, back-barrier lagoons and dune systems. Palaeoenvironmental Sampling Radiocarbon dating is based on the principle that all living organisms absorb carbon dioxide during their lifetime, and that after death, a proportion of that carbon which is radioactive (radiocarbon or 14C), decays at a constant rate. By measuring the amount of 14C remaining in plant material, shells or bone, an estimate how long ago that organism was alive can be made. Radiocarbon dating is generally suitable for samples ranging from a few hundred years old up to 50,000 years old, ideally suited to the timeframe under consideration by the CHERISH Project. Advances in analytical techniques mean that very small samples containing as little as 2 mg of carbon can be dated,

Geophysical Survey

Introduction For many of the archaeological sites and monuments on land within the CHERISH project, what you see on the surface in the forms of walls and earthwork structures is only half the story. For many monuments there are buried features, including wall foundations and ditches, beneath the surface of
