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 contains marine organic matter source samples, artificial mixtures of known composition, and compound-specific nitrogen stable isotope data of amino acids (δ¹⁵N-AA). Source materials include phytoplankton, zooplankton, and faecal pellets from the marine fouling species Mytilus edulis and Metridium senile. Samples were collected and processed in the laboratory under controlled conditions. Artificial mixtures were prepared by combining source materials in defined proportions to generate experimental samples representing multiple marine organic matter source combinations. Metadata describing sample collection, preparation, and mixture composition are included. Compound-specific nitrogen isotope ratios of individual amino acids were measured using stable isotope analysis. The dataset includes isotopic measurements for all source samples and artificial mixtures, along with associated metadata required to document sampling, laboratory preparation, and analytical procedures.

This datasets is a summary of the CTD profiles measured with the RV Belgica. It provides general meta-information such as the campaign code, the date of measurement and the geographical information. An important information is the profile quality flag that describes the validity of the data. A quality flag = 2 means the data is generally good although some outliers can still be present. A quality flag = 4 means the data should not be trusted. 1 meter binned data can be download on the SeaDataNet CDI portal (enter the cruise_id in the search bar) ONLY for the good quality profiles. Full acquisition frequency datasets are available on request to BMDC.

The Royal Decree of 20 March 2026 establishing the marine spatial plan for the period 2026 to 2034 in the Belgian marine areas defines 1 commercial and industrial zones: Zone C for commercial and industrial activities (Art. 27§1). It replaces the 2020 Marine Spatial Plan. Please refer to the Belgian official gazette ("Moniteur belgeBelgisch Staatsblad") for official reference information.

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 8, criterion 3. This dataset gives an overview of the observed slicks during aerial survey operations of the Belgian part of the North Sea (2011-2016). Related to significant acute pollution, it includes the observations linked to the Flinterstar incident in 2015. Besides this, all observations of illegal discharges of MARPOL (International Convention for the Prevention of Pollution from Ships) annex I and II substances are included as an additional dataset.

This dataset is part of the 2018 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 4, criterion 2. Three distinct datasets are published for this criterion.'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. 'Density of seabirds' describes the density of seabirds (N birds/km) observed at large in the Belgian part of the North Sea between 1987 and 2016 (three surveys a year). Thirteen species are monitored and the evolution of each species density is shown as diagrams.'Occurrence of important benthic species' describes the results of Van Veen sampling campaigns performed between 2009 and 2014 in the Belgian part of the North Sea. Benthic species are counted and identified (e.g. Annelida, Echinodermata,..).
