Marine research is truly multidisciplinary as evidenced by e.g. the EMODnet I, II, and III projects that have been running since 2009. EMODnet Geology has succeeded in bringing together harmonised offshore data including sea-floor geology, seabed substrates, rates of coastline migration, geological events and probabilities and mineral resources. The EMODnet Geology Portal aims at providing harmonised information on marine geology in Europe. It is one of several EMODnet portals with the purpose to strengthen blue growth in Europe.
