Status and conservation of facultative freshwater cetaceans in Asia

Smith, B. D.; Jefferson, T. A.
The Raffles Bulletin of Zoology (2002)

Irrawaddy dolphins Orcaella brevirostris and finless porpoises Neophocaena phocaenoides are referred to as facultative freshwater cetaceans because they occupy both fresh- and nearshore marine waters. In Asia, the especially rapid…


Pile driving playback sounds and temporary threshold shift in harbor porpoises (Phocoena phocoena): Effect of exposure duration

Kastelein, Ronald A.; Helder-Hoek, Lean; Covi, Jennifer; Gransier, Robin
The Journal of the Acoustical Society of America (2016)

High intensity underwater sounds may cause temporary hearing threshold shifts (TTSs) in harbor porpoises, the magnitude of which may depend on the exposure duration. After exposure to playbacks of pile…

During the construction of a gas pipeline from an offshore gas field in northwest Ireland, a year-round shore-based marine mammal monitoring programme was undertaken. Using 6 yr of data, generalised…


Harbour porpoises (Phocoena phocoena) and wind farms: a case study in the Dutch North Sea

Scheidat, Meike; Tougaard, Jakob; Brasseur, Sophie; Carstensen, Jacob; van Polanen Petel, Tamara; Teilmann, Jonas; Reijnders, Peter
Environmental Research Letters (2011)

The rapid increase in development of offshore wind energy in European waters has raised concern for the possible environmental impacts of wind farms. We studied whether harbour porpoise occurrence has…


Diel echolocation activity of harbour porpoises (Phocoena phocoena) around North Sea offshore gas installations

Todd, V. L. G.; Pearse, W. D.; Tregenza, N. C.; Lepper, P. A.; Todd, I. B.
ICES Journal of Marine Science (2009)

Echolocation clicks of harbour porpoises (Phocoena phocoena) were detected with T-PODs, autonomous, passive, acoustic-monitoring devices, deployed from an offshore-exploration-drilling-rig and gas-production-platform complex in the Dogger Bank region of the North…
