Zooplankton from the Belgian Part of the North Sea was sampled monthly in 2009 and 2010 at 10 monitoring stations, using a WP2 net (57cm, 200µm mesh size), which was towed in an oblique haul from bottom to surface.

This dataset is part of the long term monitoring program of ILVO at some fixed locations in the Belgian Part of the North Sea. This dataset contains the data of 2001 to 2012. This dataset will be updated with the flow of the ongoing monitoring.

Epibenthos and demersal fish monitoring in function of wind energy development. Trawl samples were taken within the wind farms (between the turbine rows, just outside the edges of the concessions and at reference stations

Macrobenthos monitoring in function of the Water Framework Directive

Epibenthos and demersal fish monitoring in function of aggregate extraction

Macrobenthos monitoring in function of the disposal of dredged material.

Epibenthos and demersal fish monitoring in function of dredge disposal monitoring

Macrobenthos monitoring in function of aggregate extraction activities. The samples were taken following a impact/control design at the locations were aggregate extraction is expected or occur.

Epibenthos and demersal fish monitoring at long-term monitoring stations Trawl samples were taken within the disposal site and outside the disposal site (close neigbourhood) (classic controle/impact design). Sampling activities were in February-March and in September/October. A 8 meter shrimp beam trawl (22 mm mesh in the cod end) equipped with a bolder chain was used.The net was towed during 30 or 15 minutes at an average speed of 4 knots.

Macrobenthos monitoring at long-term monitoring stations, period 1979-1999. This dataset contain the data of the first twenty years of benthic monitoring at ILVO in Belgian marine waters.
