The CETUS dataset contains effort-based occurrence records collected during a cetacean monitoring programme in the Eastern North Atlantic, since 2012.
In 2006, the first Dutch offshore wind farm was built 10-19 km from the shore of Egmond aan Zee. A monitoring and evalulation program accompanied the plans for the construction and exploitation of this farm. This dataset focusses on the monitoring and evaluation of potential ecological consequences in the Dutch coastal zone related to this farm for the fish community. Monitoring was executed prior to the construction of the farm (2003/2004), one year after (2007/2008) and five years after (2011). Surveys were preformed with beam trawls, pelagic nets and gillnets to study both benthic and pelagic fish communities. The monitoring is directed and the dataset is maintained by Wagening Marine Research, previously IMARES, located at Wageningen, the Netherlands. Publication of the dataset has been facilitated by Deltares, The Netherlands.
