Marine litter: new guidelines and data products online

The International Oceanographic Data and Information Exchange (IODE) of the Intergovernmental Oceanographic Commission (IOC) of UNESCO has awarded the Ocean Best Practices System Endorsement Certificate to EMODnet Chemistry’s Guide for the management of microlitter datasets. These data, along with the data on beach and seafloor litter, were used to produce the latest marine litter data collections downloadable from the EMODnet Products Catalogue. The collections in turn are used to create the maps; their latest edition was recently published in the EMODnet Map Viewer.

EMODnet’s eutrophication and ocean acidification offer is now available on ERDDAP

Building on the existing data and web services, EMODnet’s Chemistry offer of aggregated, harmonised and validated datasets on many marine chemistry parameters e.g., eutrophication and ocean acidification (first made available in 2024) are now also available through the Environmental Research Division Data Access Program (ERDDAP™), covering the Baltic Sea, Greater North Sea and Northeast Atlantic, Mediterranean Sea, Black Sea, and Arctic Ocean.

EMODnet brings its latest services to EGU 2025

EMODnet was out in force at the European Geosciences Union (EGU) General Assembly 2025 in Vienna, Austria between 27 April to 2 May 2025.The Secretariat co-chaired a session on EU marine data services for the European Digital Twin Ocean, and other presentations and posters were led by EMODnet Chemistry, Physics and Geology thematics, among others. This annual assembly is a prestigious event for Research and Innovation, typically welcoming over 18,000 global participants.

New EMODnet Biology product: Evolution of zooplankton biodiversity patterns in the Baltic Sea region

EMODnet Biology’s latest data product, developed by SMHI, offers a spatial-temporal interpolation of zooplankton biodiversity patterns across the greater Baltic Sea area, including the Skagerrak and Kattegat. Based on observed Shannon diversity indices from Swedish and Finnish environmental monitoring data, the product utilizes the DIVAnd (Data-Interpolating Variational Analysis in n-Dimensions) method to generate a three-dimensional interpolation across longitude, latitude, and seasonal time dimensions.

EMODnet Biology publishes new data products analyzing the evolution of the Community Temperature Index (CTI) of intertidal macroalgae in NW Spain.

Ocean warming is changing marine species distributions and modifying the structure of coastal communities.In the Southern part of the Bay of Biscay, climate change is affecting canopy-forming macroalgal assemblages which are turning from complex systems holding a wide range of fauna and flora to simpler systems dominated by turf-forming species with warmer affinities. This transition has negative effects on biodiversity, but also in the ecosystem services provided by those organisms with further consequences in associated sectors such us fisheries or tourism.
