Aquatic Mammals (2019)
Temporary hearing threshold shift (TTS) caused by fatiguing sounds in the 1.5 to 16 kHz range has been documented in harbor porpoises (Phocoena phocoena). To assess impacts of anthropogenic noise…
Harbor porpoise (Phocoena phocoena) reaction to a 3D seismic airgun survey in the North Sea
Sarnocińska, Joanna; Teilmann, Jonas; Balle, Jeppe Dalgaard; van Beest, Floris M.; Delefosse, Matthieu; Tougaard, Jakob
Frontiers in Marine Science (2020)
The most common cetacean in the North Sea is the harbor porpoise (Phocoena phocoena). Underwater noise is increasingly recognized as a source of impact on the marine environment and seismic…
Effects of multiple exposures to pile driving noise on harbor porpoise hearing during simulated flights—An evaluation tool
Schaffeld, Tobias; Schnitzler, Joseph G.; Ruser, Andreas; Woelfing, Benno; Baltzer, Johannes; Siebert, Ursula
The Journal of the Acoustical Society of America (2020)
Exploitation of renewable energy from offshore wind farms is substantially increasing worldwide. The majority of wind turbines are bottom mounted, causing high levels of impulsive noise during construction. To prevent…
Effectiveness of pingers on the harbour porpoise Phocoena phocoena relicta Abel, 1905 (Cetacea: Phocoenidae) in Turkey as revealed by shore-based observations
Özsandikçi, Uğur; Gönener, Sedat
Acta Zoologica Bulgarica (2020)
The aim of the present study was to assess the effectiveness of pinger devices on the Black-Sea harbour porpoises Phocoena phocoena relicta. The study was carried out in Sinop, Turkey,…
Underwater noise pollution in China’s Yangtze River critically endangers Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis)

Environmental Pollution (2020)
Underwater sound plays an important role in some critical life functions of many aquatic animals. Underwater noise pollution has received relatively more attention in ocean systems. However, little attention has…
Using passive acoustic monitoring to investigate the occurrence of cetaceans in a protected marine area in northwest Ireland
Todd, Nicole R. E.; Cronin, Michelle; Luck, Cian; Bennison, Ashley; Jessopp, Mark; Kavanagh, Ailbhe S.
Estuarine, Coastal and Shelf Science (2020)
Under the EU Habitats Directive, cetacean species must be maintained at favourable conservation status in European waters. Whether this is achieved via protected area designation, curtailment of activities such as…
Variations in echolocation click characteristics of finless porpoise in response to day/night and absence/presence of vessel noise
Ogawa, Mayu; Kimura, Satoko S.
PLOS ONE (2023)
Small odontocetes produce echolocation clicks to feed and navigate, making it an essential function for their survival. Recently, the effect of vessel noise on small odontocetes behavior has attracted attention…
Wild harbour porpoises startle and flee at low received levels from acoustic harassment device
Elmegaard, Siri L.; Teilmann, Jonas; Rojano-Doñate, Laia; Brennecke, Dennis; Mikkelsen, Lonnie; Balle, Jeppe D.; Gosewinkel, Ulrich; Kyhn, Line A.; Tønnesen, Pernille; Wahlberg, Magnus; Ruser, Andreas; Siebert, Ursula; Madsen, Peter Teglberg
Scientific Reports (2023)
Acoustic Harassment Devices (AHD) are widely used to deter marine mammals from aquaculture depredation, and from pile driving operations that may otherwise cause hearing damage. However, little is known about…
The first case of reintroduction and behavioral adaptability of Yangtze finless porpoise
Qiu, Jian-Song; Sun, Xiao-Dong; Wang, Ding; Hao, Yu-Jiang; Zheng, Jing-Song; Li, Wei-Lun; Fan, Fei; Deng, Xiao-Jun; Mao, Jun-Feng; Zeng, Qiang; Jiang, Hua-Yan; Deng, Zai-Gui; Gong, Cheng; Xu, Chun-Yong; Wang, Ke-Xiong; Mei, Zhi-Gang
Acta Hydrobiologica Sinica (2023)
The ex situ conservation of the first-class protected animal in China, Yangtze finless porpoise (YFP), have gained preliminary success. As the last step in ex situ conservation, reintroduction is an…
Ship noise causes tagged harbour porpoises to change direction or dive deeper
Frankish, Caitlin K.; von Benda-Beckmann, Alexander M.; Teilmann, Jonas; Tougaard, Jakob; Dietz, Rune; Sveegaard, Signe; Binnerts, Bas; de Jong, Christ A. F.; Nabe-Nielsen, Jacob
Marine Pollution Bulletin (2023)
Shipping is the most pervasive source of marine noise pollution globally, yet its impact on sensitive fauna remains unclear. We tracked 10 harbour porpoises for 5–10 days to determine exposure…
