What is EMODnet?

Your gateway to marine data in Europe

The Challenge...

  Data from the marine environment are a valuable asset. Rapid access to reliable and accurate information is vital in addressing threats to the marine environment, in the development of policies and legislation to protect vulnerable areas of our coasts and oceans, in understanding trends and in forecasting future changes. Likewise, better quality and more easily accessible marine data is a prerequisite for further sustainable economic development, so-called ‘blue growth’.


  Unfortunately, marine data collection, storage and access in Europe has been carried out in a fragmented way for many years. Most data collection has focused on meeting the needs of a single purpose by a wide range of private and public organisations, often in isolation from each other.


...The Solution

  The European Marine Observation and Data Network (EMODnet) is a network of organisations supported by the EU’s integrated maritime policy. These organisations work together to observe the sea, process the data according to international standards and make that information freely available as interoperable data layers and data products.


  This "collect once and use many times" philosophy benefits all marine data users, including policy makers, scientists, private industry and the public. It has been estimated that such an integrated marine data policy will save at least one billion Euros per year, as well as opening up new opportunities for innovation and growth.


How does EMODnet work?

EMODnet provides access to European marine data across seven discipline-based themes:



Seabed habitats




Human activities

For each of these themes, EMODnet has created a gateway to a range of data archives managed by local, national, regional and international organisations. Through these gateways, users have access to standardized observations, data quality indicators and processed data products, such as basin-scale maps. These data products are free to access and use.

What is available?

EMODnet is a long term marine data initiative. It has been developed through a step-wise approach and is currently in its third and final development phase. Available data are used to create and make available multi-resolution maps of all Europe’s seas and oceans, spanning all seven disciplinary themes. More than 120 partner organisations are currently involved in the EMODnet programme; new contributors are always welcome via the EMODnet Associated Partnership Scheme.

User requirements are a priority for EMODnet, so a series of 'Sea-basin Checkpoints' were established to assess how findable, accessible, interoperable and re-usable marine data are in all European sea-basins, starting with the Mediterranean and North Sea in 2013 and extending to the Arctic, Atlantic, Baltic Sea and Black Sea in 2015. These Checkpoints have acted as surrogate users attempting to address a number of simulated user challenges (windfarm siting, predicting the fate of an oil spill at sea etc.). In doing so, they assessed and reported for each sea-basin on the adequacy of the data, in terms of what is available and how useful it is. While the first cycle of assessments have been completed, more information about EMODnet Checkpoints and their results are are still relevant and available.

To further increase the quantity and quality of available European marine data, the EMODnet Data Ingestion Portal was launched in 2017. It takes a pro-active and strategic approach, to target datasets that can fill key gaps by reaching out to other initiatives or specific communities that are collecting data but who do not traditionally share their data, such as the private sector. As we move towards a fully operational EMODnet, it will continue to strengthen its collaboration with other marine knowledge providers, including fisheries, the marine component of the EU’s Copernicus programme and the private sector, to create a common platform for marine data in Europe.



  • Collect data once and use it many times;
  • Develop standards across disciplines as well as within them;
  • Process and validate data at different levels. Structures are already developing at national level but infrastructure at sea-basin and European level is needed;
  • Provide sustainable financing at an EU level so as to extract maximum value from the efforts of individual Member States;
  • Build on existing efforts where data communities have already organized themselves
  • Develop a decision-making process for priorities that is user-driven;
  • Accompany data with statements on ownership, accuracy and precision, and
  • Recognise that marine data is a public good and discourage cost-recovery pricing from public bodies.


Access to marine data is of vital importance for marine industries, decision-making bodies and scientific research. An effective pan-European marine data infrastructure will:

  • Enable effective and efficient marine spatial planning and legislation for environment, fisheries, transport, border control, customs and defence;
  • Reduce uncertainty in our knowledge and ability to forecast the behaviour of the sea;
  • Improve offshore operators’ efficiency and costs in gathering and processing marine data for operational and planning Purposes;
  • Stimulate competition and innovation in established and emerging maritime sectors;
  • Find out more about the benefits that EMODnet offers to the public sector, private sector, scientific research community and society. These are further demonstrated in the EMODnet Use Cases.
