EMODnet Human Activities, Environment, Regional Sea Conventions Marine Protected Areas

The dataset on Marine Protected Areas (MPAs) established under the framework of the Regional Sea Conventions (RSCs) was created in 2023 by Cogea for the European Marine Observation and Data Network (EMODnet). It is based on spatial data provided by HELCOM, by SPA/RAC and MedPAN through the MAPAMED database, and by OSPAR. It is available for viewing and download on EMODnet web portal (Human Activities, https://emodnet.ec.europa.eu/en/human-activities). The dataset displays all the MPAs as officially reported by the respective Contracting Parties to the Helsinky Convention, to the Barcelona Convention and to the Convention for the Protection of the Marine Environment of the North-East Atlantic. The RSCs MPAs are established in order to promote the cooperation in the management and conservation of natural areas, as well as in the protection of threatened species and their habitats. Each RSC MPA may be established in the marine and coastal zones subject to the sovereignty or jurisdiction of the Parties and in areas situated partly or wholly on the high sea. Thus, the dataset covers the MPAs Beyond National Jurisdiction (ABNJ) and the MPAs in following countries: Albania, Algeria, Belgium, Cyprus, Denmark, Estonia, Finland, France, Germany, Iceland, Ireland, Italy, Latvia, Lebanon, Lithuania, Monaco, Morocco, Netherlands, Norway, Poland, Portugal, Russia, Slovenia, Spain, Sweden, Tunisia, and the United Kingdom.

For further information please visit the data providers websites. This dataset covers the last updated versions released in the 2021 and 2022 by HELCOM and MAPAMED, and in the 2024 by OSPAR.
North East Atlantic Ocean - Eutrophication and Acidity aggregated datasets 1921/2022 v2023

EMODnet Chemistry aims to provide access to marine chemistry datasets and derived data products concerning eutrophication, acidity and contaminants. The importance of the selected substances and other parameters relates to the Marine Strategy Framework Directive (MSFD). This aggregated dataset contains all unrestricted EMODnet Chemistry data on eutrophication and acidity, and covers the Northeast Atlantic Ocean (40W). Data were aggregated and quality controlled by 'IFREMER / IDM / SISMER - Scientific Information Systems for the SEA'  in France.
ITS-90 water temperature and water body salinity variables have also been included ('as are') to complete the eutrophication and acidity data. If you use these variables for calculations, please refer to SeaDataNet for the quality flags: https://www.seadatanet.org/Products/Aggregated-datasets.
Regional datasets concerning eutrophication and acidity are automatically harvested, and the resulting collections are aggregated and quality controlled using ODV Software and following a common methodology for all sea regions ( https://doi.org/10.13120/8xm0-5m67). Parameter names are based on P35 vocabulary, which relates to EMODnet Chemistry aggregated parameter names and is available at: https://vocab.nerc.ac.uk/search_nvs/P35/.
When not present in original data, water body nitrate plus nitrite was calculated by summing all nitrate and nitrite parameters. The same procedure was applied for water body dissolved inorganic nitrogen (DIN), which was calculated by summing all nitrate, nitrite, and ammonium parameters. Concentrations per unit mass were converted to a unit volume using a constant density of 1.025 kg/L.
The aggregated dataset can also be downloaded as an ODV collection and spreadsheet, which is composed of a metadata header followed by tab separated values. This spreadsheet can be imported to ODV Software for visualisation (more information can be found at: https://www.seadatanet.org/Software/ODV).
