Multibeam and pinger survey of shipwrecks in the North Atlantic Ocean. The overall scientific goal of this application is to acquire very high-resolution data over World War I (WWI) wrecks in the Irish Sea which will be used for archaeological, biological and physical processes research, 3D visualization and cultural heritage management. This overall aim is broken down into six objectives: * To examine the physical processes occurring around these sites (on a local and regional scale) which are responsible for their preservation or destruction. * To conduct computational fluid dynamic (CFD) modelling at select wreck sites with a view to understanding fluid flow, scouring and preservation issues. * To investigate the diversity of marine life on and around the unique ecological habitats created by the wrecks . * To build up a unique high-resolution image gallery of these wrecks which can be used in public outreach allowing otherwise inaccessible sites to be enjoyed by current and future generations. * To enhance the positional record and identification data on WWI wreck sites in the Irish Sea. * To collect data that can be used for future studies into impact of the (chemical) pollution these wrecks have on the seabed and its biology.
