This report is a contribution to the Strategic Environmental Assessment (SEA6) conducted by the Department of Trade and Industry (now Department of Energy and Climate Change). In this report maritime archaeology refers to archaeology based on the investigation of the remains of ships, boats, maritime infrastructure and such other material remains as provide insights into past societies by way of their seafaring and sea-use. Archaeological issues relating to the wrecks of aircraft are not included.
After summarising the legislative framework applicable to maritime archaeology, e.g. Protection of Wrecks Act 1973, the history of maritime activity in the Irish Sea from the Palaeolithic times to the present day is reviewed. Examples of historic wrecks, some found in recent years by divers, are given. The spatial distribution of maritime archaeological remains is considered and the possible impacts of oil and gas activities are described. The report concludes with an outline of the methods used in investigating maritime archaeological remains.
