SIBES — Synoptic Intertidal Benthic Survey — is a monitoring scheme for sampling intertidal macrofauna across the Dutch Wadden Sea. It is partly funded by NAM for the ecological monitoring of the gas drilling areas in the eastern Wadden Sea.
The systematic monitoring data obtained with SIBES are an essential component of the many studies explaining how animals (birds, fish) distribute, and how their survival prospects depend on habitat use.
A carefully designed sampling design
SIBES uses a gridded sampling design that encompasses the entire Dutch Wadden Sea, with a combination of sample points taken at 500m intervals, and additional random sample points. Thus, it maximises effectiveness at minimal costs.
Dedicated field workers cover extensive terrain
Each summer a team of 8 scientists and many volunteers go out with NIOZ’s RV Navicula to take benthic samples.
