The EMODnet EC in situ marine data service is enabled by a large expert community of technical experts in thematic data, data and web services, data ingestion and more. One year on from the launch of EMODnet’s unified Portal, EMODnet launches a technical blog that brings the technical developments and achievements of the EMOD-network to the forefront, championed by EMODnet’s Technical Coordinator, Conor Delaney. The blog is intended for wider stakeholders who use and/or contribute to EMODnet and would like to know more about the latest state-of-the-art in EMODnet services. The technical blog will be released quarterly.
