Heritage Science is currently emerging as a new discipline and this book forms a comprehensive volume that addresses key topical areas of heritage science and discusses the threats to a wide range of heritage materials and monuments by biological and chemical agents of decay. Heritage Microbiology and Science: Microbes, Monuments and Maritime Materials also provides up-to-date information on subjects covering the component field of heritage microbiology, molecular and chemical analytical techniques, and the mechanisms of degradation and deterioration of historic ships and buildings. An extensive range of case studies of important world heritage artefacts and monuments as well as an overview of in situ preservation of historic ships is demonstrated. The book details state-of-the-art techniques for the study of large and small heritage objects, and their conservation. Techniques cover the use of GIS image processing, molecular biological analysis of environmental samples including FISH, electrophoresis to remove corrosive ions and synchrotron radiation to detect chemicals present in artefacts. Detailed information is included on molecular and synchrotron techniques to assist with identifying biological and chemical threats to heritage artefacts and monuments. . Several authors have developed their methods through involvement in international collaborative projects such as BIOBRUSH, BACPOLES and Save the Vasa. Extensive emphasis is placed on case studies and there is a valuable section on historic ships covering the preservation of HMS Victory, ss Great Britain, Vasa and the Mary Rose. Contributions are presented as fully referenced research publications giving useful technical details and identification of areas for future study. The book serves as an indispensable guide and reference source for those working in all areas of historical conservation, biodeterioration, microbiology and materials science.

Eric May is Reader in Microbiology at the School of Biological Sciences, University of Portsmouth. He has been known for his work on the role of bacteria in stone deterioration for 20 years but also recently coordinated an EU study to assess the value of biotechnology for remediation of altered stone in buildings (BIOBRUSH). He chaired the scientific committees and organised the international heritage meeting Heritage Microbiology and Science (HMS 2005) in Portsmouth in June 2005 along with Mark Jones at the Mary Rose Trust. He is co-editor of Conservation Science: Heritage Materials and was a participant in a recent Preserving the Past research initiative that looked at the methods used in heritage and conservation work. Mark Jones is Head of Collections at the Mary Rose Trust. A leading conservation scientist, involved with the Mary Rose Trust since 1983, Dr Jones devised the conservation methodology for the hull and wooden artefacts at the Mary Rose Trust and is now responsible for all conservation matters. His principle research interests lie in the structure and degradation of archaeological wood, acid problem in treated and untreated archaeological wood and his conservation interests include the stabilisation of large waterlogged wooden objects. He is also responsible for the conservation of the Dover Bronze-Age Boat, a third century Gallo-Celtic Boat from Guernsey, the tenth century Graveney Boat for the National Maritime Museum and numerous pre-historic logboats. Dr Jones also leads a team of textile conservators working to conserve the fore-top sail of HMS Victory for display to the general public. Julian Mitchell is a Senior Lecturer in Microbial Genetics at the School of Biological Sciences, University of Portsmouth. He is a molecular biologist with an interest in the application of molecular techniques to the study of microbes in the environment.
