Narrative summary of datasetOWEZ (Offshore Windpark Egmond aan Zee), sampling locations and sample data from fish surveys (mainly trawls). The sampling programme for T1 and T2 is identical to the baseline (T0) programme but differs from the earlier proposed program in three aspects: 1. We did not collect age data from fish as we can easily estimate ages from the measured length, frequency by Age, Length keys. 2. Stomach content data was collected as it is important to describe the relationship between benthic fauna and fish well. 3. The cables that connect the turbines in the OWEZ are orientated perpendicular to the coastline. During the baseline, all sampling transects were taken parallel to the coastline. In order to avoid damage to the cables in the OWEZ and to be consistent in reference areas, during T1 and T2 all transects will be carried out parallel to the cables and thereby perpendicular to the coast
Summary of processing methodologyData is collected by Wageningen Marine Research. After that, the data are standardized and made avaiable via a web service in AQUO format ( These data will be used as input in transformation to OBIS
