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.

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.

The Scientific Service Management Unit of the Mathematical Model of the North Sea of the Royal Belgian Institute for Natural Sciences has been operating monitoring stations on the Belgian Part of the North Sea since the 1970s. These stations are located in the Scheldt estuary, at open sea and in coastal waters. In 2007, 10 new stations were designated and were placed in the monitoring network needed for the OSPAR convention, the Water Framework Directive and the Marine Strategic Framework Directive. These replaced a series of 54 previous monitoring stations whose data was gathered throughout the years for the Belgian Monitoring Programme and reported according to the recommendations of the OSPAR Convention. This dataset contains information on all monitoring stations ever used by the Scientific Service Management Unit of the Mathematical Model of the North Sea. The dataset provides location, name, operational history and for which reporting obligations they are used.

The Royal Decree of 22 May 2019 establishing a marine spatial plan defines 8 scientific research, recreation, radars and masts zones: Scientific research (Art. 19§1), Area for test projects (Art. 19§2), Calibration of acoustic measuring devices (Art. 19§3), Industrial research and demonstration projects (Art. 19§4), Reference zone for monitoring impact of windmills and sand exploitation (Art. 19§5), Recreative activities (Art. 20§1), Recreative fisheries (Art. 20§2), Beaconing and installation of measuring poles, radars and masts (Art. 21§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. 15, four zones designated for scientific research, recreative activities, radars and masts: one for scientific research (Art. 15. § 1, the whole Belgian Part of the North Sea), one for recreative activities (Art. 15. § 2, the whole Belgian Part of the North Sea) and one for radars and masts (Art. 15. § 4, the whole Belgian Part of the North Sea) and one for industrial research, experimentations in realistic conditions and demonstration projects (Art. 15. § 5, the whole Belgian Part of the North Sea). 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 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 5 commercial and industrial zones: Zone A for commercial and industrial activities (Art. 23§1), Zone B for commercial and industrial activities (Art. 23§1), Zone C for commercial and industrial activities (Art. 23§1), Zone D for commercial and industrial activities (Art. 23§1), Zone E for commercial and industrial activities (Art. 23§1). 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 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.

The Royal Decree of 22 May 2019 establishing a marine spatial plan defines 6 measuring poles: Measuring pole MOW.0 (Art. 21§2), Measuring pole MOW.1 (Art. 21§2), Measuring pole MOW.2 (Art. 21§2), Measuring pole MOW.3 (Art. 21§2), Measuring pole MOW.4 (Art. 21§2), Measuring pole Westhinder (Art. 21§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. 15. §3, one set of measuring pole locations. These locations are made available digitally in the resource described by this metadata document.
