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…
Population survey showing hope for population recovery of the critically endangered Yangtze finless porpoise
Huang, Jie; Mei, Zhigang; Chen, Mao; Han, Yi; Zhang, Xinqiao; Moore, Jeffrey E.; Zhao, Xiujiang; Hao, Yujiang; Wang, Kexiong; Wang, Ding
Biological Conservation (2020)
The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis), has experienced rapid declines in recent decades. We estimate its abundance based on surveys conducted between November and December 2017 in the main-stem…
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…
Porpoise click classifier (PorCC): A high-accuracy classifier to study harbour porpoises (Phocoena phocoena) in the wild
Cosentino, Mel; Guarato, Francesco; Tougaard, Jakob; Nairn, David; Jackson, Joseph C.; Windmill, James F. C.
The Journal of the Acoustical Society of America (2019)
Harbour porpoises are well-suited for passive acoustic monitoring (PAM) as they produce highly stereotyped narrow-band high-frequency (NBHF) echolocation clicks. PAM systems must be coupled with a classification algorithm to identify…
Using reflected clicks to monitor range and depth of Atlantic harbour porpoises
Sanderson, B.; Adams, M.; Redden, A.
The Journal of Ocean Technology (2019)
Detection of the time of arrival of a harbour porpoise click at several synchronized broadband hydrophones, attached to a drifter, provides a method for locating porpoise and assessing any interactions…
Quantifying harbour porpoise foraging behaviour in CPOD data: Identification, automatic detection and potential application
Berges, B. J. P.; Geelhoed, S. C. V.; Scheidat, M.; Tougaard, J.
Wageningen Marine Research Reports (2019)
Harbour porpoises (Phocoena phocoena) are regularly monitored to assess how they are impacted by the construction and operation of offshore wind farms. A suitable method to do this is passive…
Baseline presence of and effects of tidal turbine installation and operations on harbour porpoise in Minas Passage, Bay of Fundy, Canada
Tollit, D.; Joy, R.; Wood, J.; Redden, A.; Booth, C.; Boucher, T.; Porskamp, P.; Oldreive, M.
The Journal of Ocean Technology (2019)
Harbour porpoise echolocation activity within and outside of the FORCE tidal turbine demonstration area in Minas Passage of the upper Bay of Fundy, Nova Scotia, has been monitored by up…
Comparison of co-deployed drifting passive acoustic monitoring tools at a high flow tidal site: C-PODs and IcListenHF hydrophones
Adams, M.; Sanderson, B.; Porskamp, P.; Redden, A.
The Journal of Ocean Technology (2019)
Porpoise click detectors (C-PODs) and icListenHF hydrophones that record with a high sample rate were deployed on a drifter in fast tidal currents in Minas Passage, Bay of Fundy, on…
Time and tide: Seasonal, diel and tidal rhythms in Wadden Sea harbour porpoises (Phocoena phocoena)
Zein, Beate; Woelfing, Benno; Dähne, Michael; Schaffeld, Tobias; Ludwig, Stefan; Rye, Jacob Hansen; Baltzer, Johannes; Ruser, Andreas; Siebert, Ursula
PLOS ONE (2019)
Odontocetes have evolved a rich diversity of prey- and habitat-specific foraging strategies, which allows them to feed opportunistically on locally and temporally abundant prey. While habitat-specific foraging strategies have been…
Pingers reduce the activity of Burmeister’s porpoise around small-scale gillnet vessels
Clay, T. A.; Alfaro-Shigueto, J.; Godley, B. J.; Tregenza, N.; Mangel, J. C.
Marine Ecology Progress Series (2019)
Incidental mortality (bycatch) in gillnet fisheries is a major threat to many cetacean populations. Acoustic alarms or pingers are a widely adopted management tool used to deter dolphins and porpoises…
