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.

This dataset is part of the 2018 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 7, criterion 1. This dataset describes the impact of an offshore windmills farm on the hydrodynamics in the Belgian part of the North Sea (BPNS). Originally, it is a NetCDF file with the results of the reference simulation made with the COHERENS (COupled Hydrodynamical Ecological model for REgioNal Shelf seas) hydrodynamic model only forced by tides (no wind effect). Model resolution : ~ 12.5m. It contains both the reference situation which is a simulation without any windmill and the modeling result of the influence by the windmills on the hydrodynamic in the BPNS. The dataset contains the results on the most inner nested grid level for one reference spring-neap cycle: - hourly sea surface elevation - hourly bottom shear stress - hourly 3D horizontal velocity components (u,v) - hourly 3D eddy viscosity - time-averaged bottom shear stress over the reference spring-neap cycle - percentile 90 of the bottom shear stress for the reference spring-neap cycle - percentile 90 of the specific kinetic energy at the sea bed - accumulated time during which sedimentation processes are dominant - accumulated time during which re-suspension processes are dominant.

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 exact location of active telecommunication cables (verified in 2010) installed in the Belgian Part of the North Sea.

This dataset represents the exact location of gas pipelines installed in the Belgian Part of the North Sea.

This dataset is part of the 2018 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 1, criterion 3. Occurrence of breeding seabirds describes the observation of eight seabird species (Common tern, Black-headed Gull, Herring Gull, Common Gull, Small Black-backed Gull, Yellow-legged gull, Big Stern and Little Stern) on the Belgian coast between 1992 and 2015.

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.

The Royal Decree of 22 May 2019 establishing a marine spatial plan defines 7 cultural heritage (wrecks) zones: 'HMS Briljant' wreck (Art. 22), 'SS Kilmore' wreck (Art. 22), '’t Vliegend Hart' wreck (Art. 22), 'U-11' wreck (Art. 22), 'West Hinder' wreck (Art. 22), Wooden wreck 'Oostende' (Art. 22), Wreck site 'Buiten Ratel' (Art. 22). 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 6, criterion 1. This dataset describes and maps the the physical loss of the seabed in the Belgian part of the North Sea (BPNS) in the period 2011-2016. The dataset combines the different human activities responsible for a loss of seabed, including wrecks, measuring piles and radar stations, pipelines, power and telecommunication cables with their rock dump, and wind farms. The area lost is mapped and quantified per year, per activity and per benthic broad habitat.

This dataset is part of the 2018 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 1, criterion 1. Stranded porpoises often show traces of incidental catch in fishing nets (bycatch), a major cause of death for this cetacean in the North Sea. Based on the number of stranded animals showing traces of bycatch, it can be estimated that up to a few dozen porpoises are caught per year. For extrapolation of bycatch data to effects at population level, reference is made to (future) initiatives at regional level.
