Biotic and abiotic data from the baseline study in 2021 for the Westdiep Seafarm and the follow up monitoring of 2022 and 2023. This dataset presents findings from an environmental impact assessment conducted along a gradient extending northeastward from a shellfish farm concession zone. Samples were collected at 20 locations in 2021, and then 10 in 2022 and 2023, using a 0.1 m² Van Veen Grab, assessing sediment grain size distribution and total organic carbon content. Macrobenthos samples were preserved, stained, and analyzed in the laboratory.

Macrobenthos samples were collected in triplicate at 20 locations along the gradient using a 0.1 m² Van Veen Grab. From these 20 locations 10 were selected to follow up with the monitoring in 2022 and 2023. The grain size distribution was measured using laser diffraction with a Malvern Mastersizer. The TOC content in each sample was measured by combustion using an ELTRA CS2000 with infrared cells after acidifying the samples. On board, the Van Veen grab samples were sieved over a 1 mm mesh-sized sieve, and the macrobenthos was preserved in 4% formaldehyde-seawater solution. The samples were then stained with 1% Rose Bengal. In the laboratory, organisms were sorted, counted and identified to the lowest taxonomic level. Data were quality checked and flagged accordingly.
