IMARES conducted studies in 2012 and 2013 to monitor offshore bat activity with passive acoustic ultrasonic recorders. In the follow-up project reported here, more data on the offshore occurrence of bats was collected in 2014. Using the same methodology as in 2012 and 2013, bat activity was monitored from spring to autumn in both wind farms (OWEZ & PAWP) and two additional locations: the IJmuiden meteorological mast (85 km west of Callantsoog) and at the coast near Egmond aan Zee.
