Access to archived and real-time data on the physical conditions of European sea-basins and oceans is important for a wide range of users and for many different reasons; to monitor sea level variability, to make predictions on climate change or for the operation and planning of off-shore activities. Physical parameters include; sea water salinity and temperature, currents, turbidity, wind direction and speed, sea level and ice cover.


Objectives of EMODnet Physics

The overall objective of EMODnet Physics is to provide access to archived and near real-time data on the physical conditions of European seas and oceans based on observation of the sea, such us wave height and period; temperature of the water column; wind speed and direction; salinity of the water column; horizontal velocity of water column; water clarity; changes in sea-level; data from rivers; ice cover; underwater sound. The portal provides full interoperability with third-party software through WMS services, Web Services and Web catalogues in order to exchange data and products according to the most recent standards.

Key Services provided by EMODnet Physics

The EMODNet Physics portal provides a combined array of services and functionalities to users for viewing and downloading data, meta-data and data products on the physical conditions of European sea basins and oceans. Currently the following key services and functionality are provided for users:


EMODnet Physics is founded on the three established pillars of the European oceanographic landscape, namely; the EuroGOOS-ROOSs (Regional Operational Oceanographic Systems), the Copernicus Marine Environment Monitoring Service (CMEMS) and the SeaDataNet network of National Oceanographic Data Centres (NODCs). EMODnet Physics is an operational service where near real time and historical validated marine data is made interoperable and freely available. It is built in cooperation and coordination with EuroGOOS-ROOSs (Regional Operational Oceanographic Systems) and  on other existing European integrators infrastructures such as the Copernicus Marine Environment Monitoring Service (CMEMS) and SeaDataNet. The portal provides full interoperability with third-party software through WMS services, Web Services and Web catalogues in order to exchange data and products according to the most recent standards.

Data Sources

Physical data sets are made available via EMODnet Physics through the collaborative efforts of EuroGOOS associates and their regional operational systems (ROOSs), the CMEMS in-situ TAC system and the SeaDataNet consortia. EMODnet Physics is fully integrated with, and complementary to, the marine core services of Copernicus marine service (CMEMS).

The EMODnet Physics portal will give access to two major data streams:

  1. Near real-time (NRT) data made available within 8 hours of acquisition, collected for operational needs at fixed measuring stations (e.g. moored buoys, rigs/platforms, coastal stations) and by automatic observatories at sea (e.g. profiling floats, drifting buoys, ferrybox, ships of opportunity, research vessels) and which are transmitted in near real-time to the shore;
  2. Archived data derived from further elaboration and validation of the near real-time (NRT) data.

The access to the NRT data stream is supported by the EuroGOOS-ROOSs and the CMEMS in-situ TAC system, whilst metadata discovery to the archived data is organised through the SeaDataNet infrastructure. The Coriolis infrastructure of Ifremer is also playing an important role in providing access to the supplementary data from Argo floats (EuroArgo).

EMODnet Physics data product development

EMODnet Physics are developing data products to enhance existing services, such as defining temporal and spatial windows for data viewing via a dynamic map facility, as well as providing new data products with application for Marine Strategy Framework Directive (MSFD) implementation, such as riverine input, underwater noise monitoring of sea level change and ice coverage.

Improvements in the current development Phase III (2017-2020)

 This phase will will improve and expand the data portal in order to:

  • Provide better access to additional data not yet in the current system, including access to data on underwater noise and riverine inputs (from major rivers).
  • Streamline and optimise the data flow;
  • Fully exploit opportunities to obtain additional parameters from existing data sites;
  • Fill in gaps in time series;
