Description: Archaeological Discoveries from the Marine Aggregate and Offshore Wind IndustriesThe Marine Aggregate Industry (MAI) Protocol for Reporting Finds of Archaeological Interest provides a scheme for companies working in the UK aggregates industry to report archaeological material discovered during dredging operations or encountered in aggregate material at wharves.The MAI Protocol is in partnership with the British Marine Aggregate Producers Association (BMAPA), The Crown Estate and Historic England (formerly English Heritage), and is implemented by Wessex Archaeology. Since its launch in 2005, over 1,600 objects have been reported through the Protocol (correct as of April 2017).The MAI Protocol ensures that as much information about each discovery is gained through research undertaken by Wessex Archaeology. Corresponding reports are disseminated back to the relevant aggregates company and also to the regional and national heritage archive bodies.The coordinates for locations of discoveries made through the MAI Protocol predominantly relate to either the centrepoint of the active dredging licence area (available from The Crown Estate website) or the centrepoint of a trackplot of the dredging vessel supplied by the contractor. Only occasionally do the finds represent the actual location of their discovery. All WGS84 (EPSG:4326) coordinates are given in Decimal Degrees to six decimal places.The Offshore Renewables Protocol for Archaeological Discoveries (ORPAD) is a scheme for developers working in the UK offshore renewables industry to report any archaeological sites and material encountered during their investigation of the seabed undertaken throughout all stages of the development, but predominantly the pre-consent and installation phases of wind farm developments. The logistical difficulties of working at sea mean that despite record searches, geophysical surveys and deploying divers or sub-surface vehicles to areas within a development area, there is still high potential for discrete finds and previously unknown or buried sites to be revealed.ORPAD was launched in 2010 as a joint venture between The Crown Estate (who fund the project) and Wessex Archaeology (the implementation service), and since then over 530 archaeological discoveries have been reported (correct as of October 2016). ORPAD helps protect these archaeological discoveries by establishing a framework through which any unexpected archaeological remains, which range from aircraft remains and articulated shipwrecks to single anchors, historical unexploded ordnance (UXO) and palaeoenvironmental remains, can be investigated before any information is lost.Wessex Archaeology researches these finds and produces reports that are disseminated back to the relevant developer and also to the regional and national heritage archive bodies.The WGS84 (EPSG:4326) coordinates for the locations of sites and material reported through ORPAD are given in Decimal Degrees to three decimal places. The accuracy of the position has been reduced in order to protect potentially vulnerable archaeological material.
