This dataset is part of the 2024 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 10, criterion 2. This dataset presents data on microplastics in seabed sediment along a coastal-offshore transect in the Belgian Part of the North Sea (BPNS) in 2020, during 2 cruises on board the RV Belgica. Samples were collected using a Reineck box corer or a Van Veen grab, and the top 5cm was collected for analysis. The samples were preserved and analyzed in the laboratory. This dataset also presents data on microplastics in seawater along the same coastal-offshore transect in the BPNS in 2020-2021, during 3 cruises on board the RV Belgica. Subsurface seawater was collected through the vessel's continuous seawater inlet located below the surface (-3m). The samples were preserved and analyzed in the laboratory.

This dataset is part of the 2024 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 1, criterion 2. It originates from the ICES DATRAS (Database of Trawl Surveys), which compiles standardised bottom trawl survey data collected from various European waters; for this indicator, the Belgian Beam Trawl Survey (BTS) data from the North Sea were used. The dataset includes species abundance, length and age distributions, catch per unit effort, and environmental parameters, providing key insights on the population abundance of thornback ray (Raja clavata) and lesser-spotted dogfish (Scyliorhinus canicula) for stock assessment and fisheries management.

This dataset is part of the 2024 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 (2016-2021). Besides this, all observations of illegal discharges of MARPOL annex I and II substances are included as an additional dataset.
