A consortium consisting of the national geological survey organisations of the UK, Ireland, France, Belgium, The Netherlands, Germany, Denmark, Norway, Sweden, Finland, Estonia, Latvia, Lithuania and Poland are working together to deliver the requirements of EC Tender MARE/2008/03. The geological surveys of Europe provide an existing network (through the Association of European Geological Surveys – EuroGeoSurveys) that aims to deliver marine geological information solutions to decision makers in European government and industry, as well as providing baseline information for academic research. The contract between the EC and the EMODnet‐ Geology Project partners was signed on 16 July 2009; this draft Final Report describes progress during the first three phases of the project, Phase 1. Development of the data layers and portal (months 1‐12), Phase 2. Testing and monitoring of the information layers (months 13‐18) and Phase 3. Upgrade of the system following testing (months 19‐24), which took place from July 16th 2009 to July 15th 2011
