This dataset contains marine organic matter source samples, artificial mixtures of known composition, and compound-specific nitrogen stable isotope data of amino acids (δ¹⁵N-AA). Source materials include phytoplankton, zooplankton, and faecal pellets from the marine fouling species Mytilus edulis and Metridium senile. Samples were collected and processed in the laboratory under controlled conditions. Artificial mixtures were prepared by combining source materials in defined proportions to generate experimental samples representing multiple marine organic matter source combinations. Metadata describing sample collection, preparation, and mixture composition are included. Compound-specific nitrogen isotope ratios of individual amino acids were measured using stable isotope analysis. The dataset includes isotopic measurements for all source samples and artificial mixtures, along with associated metadata required to document sampling, laboratory preparation, and analytical procedures.

This dataset is part of the 2024 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 6, criterion 4. This dataset describes and maps the areal extent of EUNIS level 2 broad-scale habitat types and gravel beds in the Belgian part of the North Sea (BPNS), to assess whether the spatial extent of these habitats fluctuates beyond the accuracy margin of the current distribution maps.

This dataset is part of the 2024 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 6, criterion 2. This dataset describes and maps the physical disturbance to the seabed in the Belgian part of the North Sea (BPNS) between 2010 and 2021. The dataset combines different layers of human activities leading to a disturbance of the seabed, including 'soft' beach and foreshore nourishments, dredging and dumping, sand extraction, fisheries, burial of cables, war ammunition stocking and construction of wind farms. The area disturbed is mapped and quantified per year and per activity, and plotted on the predominant broad-scale benthic habitat types of the EUSeaMap 2023. Infield cables from wind farms and Elia cables (NEMO and MOG) are not shown due to mutual agreements. This dataset is part of the 2024 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 6, criterion 1. This dataset describes and maps the physical loss of the seabed in the Belgian part of the North Sea (BPNS) between 2010 and 2021. The dataset combines different layers of human activities leading to a loss of the seabed, including 'hard' coastal defence structures, ports, measuring poles and radar station, protection of pipelines and cables, construction of wind farms, and wrecks and other obstacles. The area lost is mapped and quantified per year and per activity, and plotted on the predominant broad-scale benthic habitat types of the EUSeaMap 2023.

This dataset is part of the 2024 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 6, criterion 5. It reports on the condition of benthic habitats in the Belgian part of the North Sea (BPNS), combining soft-sediment macrobenthos monitoring (in the framework of dredge disposal/sand extraction impact assessment, and offshore wind farm monitoring) with natural hard-substrate benthos monitoring, to evaluate adverse effects on the biotic and abiotic structure and function of benthic habitat types.

This dataset is part of the 2024 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 2, criterion 1. This dataset lists the newly-introduced species encountered in the Belgian part of the North Sea (BPNS) between 2016 and 2021, combining dedicated non-indigenous species (NIS) surveys of artificial hard substrates with incidental NIS records collected during the soft-sediment and epibenthos monitoring programmes.

This dataset is part of the 2024 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 8, criterion 4. This dataset reports the proportion of oiled Common Guillemots (Uria aalge) among stranded seabirds along the Belgian coast, as an indicator of acute oil pollution (environmental target: average proportion of oiled guillemots below 10% of the total found dead or dying on the beaches).

This dataset is part of the 2024 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 1, criterion 2. This dataset reports the population abundance (number of individuals, biomass) of benthic-feeding, pelagic-feeding, surface-feeding and wading birds in Belgian waters, combining yearly breeding-colony nest counts along the Belgian coast with ship-based at-sea seabird counts.

The Royal Decree of 20 March 2026 establishing the marine spatial plan for the period 2026 to 2034 in the Belgian marine areas defines 13 dredging zones: Dredge spoil disposal zone S1 (Art. 15§1.1°), Dredge spoil disposal zone S2 (Art. 15§1.2°), Dredge spoil disposal zone "Public Works Ostend" (Art. 15§1.3°), Dredge spoil disposal zone "Public Works Zeebrugge East" (Art. 15§1.4°), Dredge spoil disposal zone "Public Works Zeebrugge West" (Art. 15§1.5°), Dredge spoil disposal site "Public Works Nieuwpoort" (Art. 15§1.6°), Dredge spoil disposal zone "Zeebrugge Erosion Pit" (Art. 15§1.7°), Zone 1 for future replacement of dredge spoil zone S1 (Art. 15§4.1°), Zone 2 for future replacement of dredge spoil zone S1 (Art. 15§4.2°), Search zone 1 for future replacement of Zeebrugge East and West (Art. 15§6), Search zone 2 for future replacement of Zeebrugge East and West (Art. 15§6), Search zone 3 for future replacement of Zeebrugge East and West (Art. 15§6), Dredge spoil disposal zone for future replacement "Public Works Nieuwpoort" (Art. 15§8). It replaces the 2020 Marine Spatial Plan. Please refer to the Belgian official gazette ("Moniteur belgeBelgisch Staatsblad") for official reference information.

This dataset is part of the 2024 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 9, criterion 1. The dataset contains the results of analyses on raw fish, molluscs and crustacean samples originating from the southern North Sea and the Channel and taken as part of the control programme by the Federal Agency for the Safety of the Food Chain in the period 2016-2021. The analyzed substances are metals (cadmium, mercury and lead), dioxins and dioxin-like PCBs, PCBs, PAHs, PFAS, Cesium 134 and Cesium 137.

This dataset is part of the 2024 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 8, criterion 1. This dataset reports concentrations of PFAS and dioxins in biota (mussels Mytilus edulis and flounder Platichthys flesus) in the Belgian part of the North Sea.
