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.

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. 9. five dredged material disposal sites (Dredged material disposal site S1, Art. 9 § 6.1°; Dredged material disposal site S2, Art. 9 § 6.2°; Dredged material disposal site Bruggen en Wegen Oostende, Art. 9 § 6.3°; Dredged material disposal site Bruggen en Wegen Zeebrugge Oost, Art. 9 § 6.4°; Dredged material disposal site Bruggen en Wegen Nieuwpoort, Art. 9 § 6.5°). 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 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 represents main data about the cores of Belgian boreholes that are stored by the Royal Belgian Institute of Natural Sciences. Data is distributed as shapefile with multiple meta-infomations such as unique borehole reference, depth, location, lithology and a link to access the core and lithological descriptions.

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 the wind turbines in the Belgian Part of the North Sea.

The Royal Decree of 22 May 2019 establishing a marine spatial plan defines 12 sand and gravel extraction zones: Sand and gravel exploitation sector 1a (Thorntonbank) (Art. 15§1), Sand and gravel exploitation sector 2br (Buiten Ratel) (Art. 15§1), Sand and gravel exploitation sector 2kb (Kwintebank) (Art. 15§1), Sand and gravel exploitation sector 2od (Oostdyck) (Art. 15§1), Sand and gravel exploitation sector 3a (Sierra Ventana) (Art. 15§1), Sand and gravel exploitation sector 3b (Sierra Ventana) (Art. 15§1), Sand and gravel exploitation sector 4a (Noordhinder) (Art. 15§1), Sand and gravel exploitation sector 4b (Oosthinder-noord) (Art. 15§1), Sand and gravel exploitation sector 4c (Oosthinder-zuid) (Art. 15§1), Sand and gravel exploitation sector 4d (Westhinder) (Art. 15§1), Sand and gravel exploitation sector 5 (Blighbank) (Art. 15§1), Zone for research of the potential of the exploration and exploitation of sand and gravel (Art. 15§4). 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. 11., eleven Management zones with regards to sand and gravel extraction: ten sand and gravel exploitation zones (Thorntonbank, Art. 11 § 1 Sector 1a, Kwintebank, Art. 11 § 1 Sector 2kb, Buiten Ratel, Art. 11 § 1 Sector 2br, Oostdyck, Art. 11 § 1 Sector 2od, Sierra Ventana, Art. 11 § 1 Sector 3a, Sierra Ventana, Art. 11 § 1 Sector 3b, Noord Hinder, Art. 11 § 1 Sector 4a, Oosthinder-noord, Art. 11 § 1 Sector 4b, Oosthinder-zuid, Art. 11 § 1 Sector 4c, Westhinder, Art. 11 § 1 Sector 4d) and one reference zone for monitoring impact of windmills and sand exploitation (Art. 11 § 3). These zones are made available digitally in the resource described by this metadata document.

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).
