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…


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…


Last call: Passive acoustic monitoring shows continued rapid decline of critically endangered vaquita

Thomas, Len; Jaramillo-Legorreta, Armando; Cardenas-Hinojosa, Gustavo; Nieto-Garcia, Edwyna; Rojas-Bracho, Lorenzo; Ver Hoef, Jay M.; Moore, Jeffrey; Taylor, Barbara; Barlow, Jay; Tregenza, Nicholas
The Journal of the Acoustical Society of America (2017)

The vaquita is a critically endangered species of porpoise. It produces echolocation clicks, making it a good candidate for passive acoustic monitoring. A systematic grid of sensors has been deployed…


Long-term passive acoustic monitoring revealed seasonal and diel patterns of cetacean presence in the Istanbul Strait

Dede, Ayhan; Öztürk, Ayaka Amaha; Akamatsu, Tomonari; Tonay, Arda M.; Öztürk, Bayram
Journal of the Marine Biological Association of the United Kingdom (2013)

The Istanbul Strait (Bosphorus) is a part of the Turkish Straits System, connecting the Aegean Sea and the Black Sea. There are three cetacean species in the Strait, namely the…


Harbour porpoise (Phocoena phocoena) static acoustic monitoring: Laboratory detection thresholds of T-PODs are reflected in field sensitivity

Kyhn, Line A.; Tougaard, Jakob; Teilmann, Jonas; Wahlberg, Magnus; Jørgensen, Poul B.; Bech, Nikolaj I.
Journal of the Marine Biological Association of the United Kingdom (2008)

The T-POD (Timing POrpoise Detector) is a self-contained acoustic data logger used for detecting and monitoring the presence of echolocation clicks of small cetaceans. It has become a standard tool…


Diurnal variation in harbour porpoise detection – Potential implications for management

Williamson, L. D.; Brookes, K. L.; Scott, B. E.; Graham, I. M.; Thompson, P. M.
Marine Ecology Progress Series (2017)

Robust information on animal distributions and foraging behaviour is required to target management and conservation measures for protected species and populations. Visual survey data are commonly used to model these…


Year-round spatiotemporal distribution of harbour porpoises within and around the Maryland wind energy area

Wingfield, Jessica E.; O’Brien, Michael; Lyubchich, Vyacheslav; Roberts, Jason J.; Halpin, Patrick N.; Rice, Aaron N.; Bailey, Helen
PLOS ONE (2017)

Offshore windfarms provide renewable energy, but activities during the construction phase can affect marine mammals. To understand how the construction of an offshore windfarm in the Maryland Wind Energy Area…


Responses of bottlenose dolphins and harbor porpoises to impact and vibration piling noise during harbor construction

Graham, Isla M.; Pirotta, Enrico; Merchant, Nathan D.; Farcas, Adrian; Barton, Tim R.; Cheney, Barbara; Hastie, Gordon D.; Thompson, Paul M.
Ecosphere (2017)

The development of risk assessments for the exposure of protected populations to noise from coastal construction is constrained by uncertainty over the nature and extent of marine mammal responses to…
