This dataset is part of the 2018 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 8, criterion 1. This dataset describes the contaminant concentrations in biota. The priority substances mercury, hexachlorobutadiene and hexachlorobenzene are measured in mussels and flounder in the BPNS. Results for other parameters that are part of the OSPAR Coordinated Environmental Monitoring Program are also included: polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), heavy metals, organotin-compounds and polybrominated diphenyl ethers (PBDEs) for the period 2011-2016. The analyses are performed by ILVO and KBIN-OD Nature that both participate in the Quasimeme ring tests for additional quality control. Bird eggs of 2008, 2010 and 2015 are measured for mercury (Hg), dichlorodiphenyltrichloroethane (DDT), hexachlorobenzene (HCB) and hexachlorocyclohexane (HCH). Eggs from the are measured and compared with OSPAR norms Common Tern (Sterna hirundo) are gathered in Zeebrugge and are analyzed by the Insitut für vogelforschung in Wilhelmshaven according to a standard protocol.

Share of the cadastral surface area that is artificially developed in the cadastral surface area and not unknown to the administrative entity (region, province, district and municipality) for Wallonia

This dataset is part of the 2018 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 2011 and 2016. The dataset combines different layers of human activities leading to a disturbance of the seabed, including power cables with its rock dump, dredging and dumping, extraction, war ammunition stocking and wind farms. The area disturbed is mapped and quantified per year, per activity and per benthic broad habitat.

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.

The Royal Decree of 22 May 2019 establishing a marine spatial plan defines 5 nature conservation areas: Special area for conservation 'The Flemish Banks' (Art. 7§1), Special area for conservation 'Vlakte van de Raan' (Art. 7§3), Special protection area for birds - SPA 1 (Art. 7§5.1°), Special protection area for birds - SPA 2 (Art. 7§5.2°), Special protection area for birds - SPA 3 (Art. 7§5.3°). 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. 7., six nature conservation sites: two special areas for conservation (Art. 7. §1, Special area for conservation 'Vlaamse Banken' and Art. 7. §3, Special area for conservation 'Trapegeer stroombank'), three special protection zones for birds (Art7§4.1°, SBZ1, Art7§4.2°, SBZ2, Art7§4.3°, SBZ3), and one marine reserve (Art7§8, Marine reserve 'Baai van Heist').

Polar volume reflectivity data from the Wideumont weather radar. Volume data files are produced every 5 minutes from a multiple elevation scan. This product is not publicly available yet.

The average household size of private households by administrative unit (region, province, district and municipality) for Wallonia.

This dataset is part of the 2018 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 1, criterion 2. The Raja clavata dataset describes the results of the Offshore Beam Trawl Surveys (BTS) in the Belgian part of the North Sea (BPNS) between 2010 and 2017. Occurrences of Raja Clavata, along with dates and locations, are reported. The codes used in the attached file are based on the ICES DATRAS (Database of Trawl Surveys) standard. The seabirds dataset describes the density of seabirds (N birds/km) observed in the BPNS between 1987 and 2016 (three surveys a year).

Annual and seasonal precipitation indices given in number of days: 1/ Wet days: Number of days with precipitation > 0.1 mm/day for winter, autumn, spring, summer; 2/ Dry days: Number of days with precipitation < 0.1 mm/day for winter, autumn, spring, summer; 3/ Average length of dry spells: Mean duration of minimum three consecutive days with precipitation < 0.1 mm/day; 4/ Maximum length of dry spells: Longest period of minimum three consecutive days with precipitation < 0.1 mm/day, occurring once in 20 years. The precipitation indices are available for the future target year 2085, which corresponds to the middle of the 30-year period 2071-2100, and for mean and high impact scenarios corresponding respectively to the 50th, and 5th or 95th percentiles of the change factors.
