It was a partnership project between partners in Wales and Ireland, and part funded by INTERREG IIIa European regional development fund. \r\n\r\nData collection included acoustic data, sediment data and seabed imagery. These data were used to classify the seabed and feed into a predictive modelling process to predict benthic habitat. \r\n\r\nThe multibeam data was collected in five locations throughout the Southern Irish Sea by the R/V Celtic Voyager to Irish National Seabed Survey (INSS) standard. They were then processed, cleaned and classified based on acoustic classes, which were then related to seabed sediment types. Bedforms were also identified using the MBES data. The Coordinate System used for the multibeam data was UTM Zone 30N. The xyz data was usually processed to a 5 m resolution. \r\n\r\nThe purpose of this data capture was to obtain multibeam coverage of the five study areas identified to cover a variety of different environments with different physical properties and biological communities. This would be used to link backscatter intensity to physical properties of the seabed. Data depth corrected for tide using POLPRED software which utilises one or more of Proudman Oceanographic Laboratory's hydrodyamic models, and reduced to chart datum. CARIS HIPS / SIPS software used to create surfaces and gridded datasets by experienced surveyors.", "includedInDataCatalog": { "@id": "http://portal.medin.org.uk/portal/json-ld/catalog.jsonld" }, "conditionsOfAccess": [ "access: There are no access restrictions to this data.
