Do man-made structures and water depth affect the diel rhythms in click recordings of harbor porpoises (Phocoena phocoena)?

Brandt, Miriam J.; Hansen, Sophie; Diederichs, Ansgar; Nehls, Georg
Mar Mam Sci (2014)

The construction of industrial offshore structures may lead to colonization by a variety of marine organisms resulting in locally enhanced biodiversity and biomass, which may then affect the habitat use…


Is a German harbour porpoise much more sensitive than a British one? Comparative analyses of mandatory measures for the protection of harbour porposes (Phocoena phocoena) during offshore wind farm ramming in Germany, Denmark and the UK

Luedeke, Jens
Proceedings of Meetings on Acoustics (2012)

Offshore wind farms (OWF) will soon contribute to significant growth in the renewable energy sector. At present just a few OWF have been built. As of 2012, Germany has an…


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…


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…


Effect of construction-related activities and vessel traffic on marine mammals

Culloch, R. M.; Anderwald, P.; Brandecker, A.; Haberlin, D.; McGovern, B.; Pinfield, R.; Visser, F.; Jessopp, M.; Cronin, M.
Marine Ecology Progress Series (2016)

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…


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…
