The importance of an integrated knowledge on seafloor sediment distribution for European seas is highlighted in work just published: "Picking up the pieces – harmonising and collating seabed substrate data for European maritime areas" in the Geosciences Special Issue on "Geological Seafloor Mapping".

The publication describes how the European Marine Observation and Data Network (EMODnet) initiated by the European Commission, has assembled and provided free access to marine geological data through a web data portal.

EMODnet Geology has collated all available seabed substrate maps for European seas to create multiple maps at different scales and Folk granularities, where Folk refers to the internationally recognised Folk classification scheme. INFOMAR contributes data on Ireland’s seabed substrate distribution from all surveyed coastal areas extending to the deeper water depths ~4500 m.

A confidence assessment of the data is provided to ensure users understand the ‘confidence’ in the map reflecting the amount of information available from acoustic data and seabed samples to create the map. INFOMAR data has an associated high level of confidence for much of the Irish offshore highlighting the benefits of full coverage survey data in Ireland’s Exclusive Economic Zone.

Information on seabed substrates is particularly valuable for marine spatial planning where it facilitates investment in sustainable coastal and offshore activities through better access to standardised marine data.
