Dutch long term monitoring of macrobenthos in the Dutch Continental Economical Zone of the North Sea, the Wadden Sea and the Southwestern Delta

Samples have been taken by benthic sledge, box-corer, video and Hamon sampler. Samples were taken annually between 1989-2024 and analysed to the genus or species level.

For video sampling, coverage percentages were measured. The dataset has been used for assessment of the marine environment and habitat quality in the scope of the OSPAR Quality Status Reports and the Marine Strategy Framework Directive.
