Observations were made to investigate the behavioral reactions of wild harbor porpoises (Phocoena phocoena) towards pingers (banana pinger (Fishtek)). We did video recordings of 16 wild porpoises with a drone (DJI Phantom 4 Professional v2.0, P4Pv2, www.dji.com) equipped with a polarizing filter (Polarpro ND8-PL). Using the drone flight records and a tailored analysis software, we were able to determine GPS coordinates of the wild porpoises. Data were collected in May and June 2019 in Kerteminde, Denmark. The purpose of the data was to record the behavior of harbor porpoises before and during exposure to pinger sounds. ...
