UNDER EMBARGO - This dataset contains seasonal physiological measurements from controlled laboratory experiments on two dominant suspension-feeding species expected to colonise floating offshore structures: the blue mussel (Mytilus edulis; AphiaID 140480) and the wrinkled barnacle (Balanus crenatus; AphiaID 106215). The measured parameters include clearance rates, respiration rates, faecal pellet production rates, and faecal pellet sinking velocities. Mussels were collected from an aquaculture longline at the Westdiep SeaFarm, while barnacles were manually retrieved from the intertidal beachhead at Raversijde (Oostende, Belgium). All experiments were conducted using natural seawater collected from offshore sites in the Belgian part of the North Sea. Measurements were repeated across multiple seasons to capture temporal variability in physiological performance. The dataset was produced within the SWiM and EcoMPV projects and is suitable for reuse in ecosystem and biogeochemical modelling, including simulations of phytoplankton dynamics associated with large-scale offshore marine photovoltaic (MPV) developments.

This dataset represents the location of the Princess Elizabeth zone in the Belgian Part of the North Sea as described in the Royal Decree of May 22th, 2019, establishing a marine spatial plan for the period 2020-2026. Art. 8. § 3.

The Royal Decree of 22 May 2019 establishing a marine spatial plan defines 11 military use and storage sites for war munition zones: Exercise area for sweeping mines (Buiten Ratel) (Art. 17§1), Exercise area for sweeping mines - NB-01 (Westhinder) (Art. 17§1), Exercise area for sweeping mines - NBH-10 (Wenduine) (Art. 17§1), Exercise area for sweeping mines - QZR 040 (Art. 17§1), Munition destruction area (Art. 17§2), Area for shooting exercises on floating objects (Art. 17§3), Area for exercises in shallow waters (Art. 17§4), Area for shooting exercises from land - big sector (Art. 17§5), Area for shooting exercises from land - medium sector (Art. 17§5), Area for shooting exercises from land - small sector (Art. 17§5), Storage site for war munition Paardenmarkt (Art. 18§1). It replaces the 2014 Marine Spatial Plan, which is included for completeness. The Royal Decree of 20 March 2014 establishing a marine spatial plan defines in its Art. 13. and Art. 14., resp. nine zones for military use and one storage site for war munition: three zones for shooting exercises from land direction sea (Art 13. § 1 small sector, Art 13. § 1 medium sector, Art 13. § 1 large sector), four exercise areas for sweeping mines (Art 13. § 3, Exercise area 1 for sweeping mines, Art 13. § 5, Exercise area 2 for sweeping mines, Art 13. § 9, Exercise area 3 for sweeping mines, Art 13. § 13, Exercise area 4 for sweeping mines), one area for shooting exercises on floating objects (Art 13. § 7), one area for defusing mines (Art 13. § 11) and one zone to safeguard the closed storage site for war munition \"Paardenmarkt\" (Art. 14. § 1). These zones are made available digitally in the resource described by this metadata document. Please refer to the Belgian official gazette (\"Moniteur belge/Belgisch Staatsblad\") for official reference information.

This dataset is part of the 2018 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, mollusk 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. The analyzed substances are metals (cadmium, mercury and lead), dioxins and dioxin-like PCBs, PCBs, PAHs, Cesium 134 and Cesium 137.

This dataset represents the exact location of disused telecommunication cables installed in the Belgian Part of the North Sea.

This dataset describes the extents and location of Sandbanks (code 1110) in the Belgian Part of the North Sea (BPNS) as required for article 17 of the Council Directive 92/43/EEC of 21 May 1992 on the conservation of natural habitats and of wild fauna and flora. The Council Directive seeks to contribute to ensuring biodiversity in the European Union by the conservation of natural habitats and wild fauna and flora species.

The dataset describes the physical habitats in the Belgian Part of the North Sea. It uses the EUNIS classification system as well as the MSFD Habitat codelist for the description and classification of the BPNS. It provides also information on the energy, biozone and type of substrate for the different areas in the BPNS.

The Royal Decree of 22 May 2019 establishing a marine spatial plan defines 1 coastal protection experiments zone: Zone for coastal protection experiments (Art. 16§2). It replaces the 2014 Marine Spatial Plan, which is included for completeness. The Royal Decree of 20 March 2014 establishing a marine spatial plan defines in its Art. 12. §1 one zone for coastal protection experiments. This zone is made available digitally in the resource described by this metadata document. Please refer to the Belgian official gazette (\"Moniteur belge/Belgisch Staatsblad\") for official reference information.

This dataset is part of the Belgian submission for the 2018 Marine Strategic Framework Directive (MSFD) and reports on descriptor 1, criterion 6. This dataset describes the soft benthos analysis performed in the Belgian part of the North Sea between 2010 and 2016. Information on the location, date and procedure used for the sediment sampling is povided as well as the description of the species found in the samples. Based on this dataset, the Belgian MSFD reporting concluded that the benthic habitat quality is clearly lower in areas where a certain activity interferes with the environment in an intensive way.

This dataset is part of the 2018 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 11, criterion 1. This dataset describes the impulsive noise generated during percussion pile emplacement for offshore wind farm construction and unexploded ordnance (UxO) explosions. Impulsive underwater sound (pressure) was measured during pile driving operations in Belgian waters, for different types of foundations (monopiles of different diameters, foundations of ducts with a smaller diameter) and hydraulic hammers with different energy powers. The results of measurements at Bligh Bank and Thornton Bank, with a resulting extrapolation of zero to peak noise level (Lz-p) at 750m and Sound Exposure Level (SEL) (no mitigation measures deployed), are presented (Norro et al., 2013).
