Effect of series of 1 to 2 kHz and 6 to 7 kHz up-sweeps and down-sweeps on the behavior of a harbor porpoise (Phocoena phocoena)
Kastelein, Ronald; Schop, Jessica; Gransier, Robin; Steen, Nele; Jennings, Nancy
Aquatic Mammals (2014)
To compare the effect of naval sonar up-sweeps and down-sweeps on the behavior of harbor porpoises, a harbor porpoise in a large pool was exposed to simulated low- and mid-frequency…
Brief behavioral response threshold level of a harbor porpoise (Phocoena phocoena) to an impulsive sound
Kastelein, Ronald; Steen, Nele; Gransier, Robin; de Jong, Christ A. F.
Aquatic Mammals (2013)
Underwater impulsive sounds may affect the behavior of harbor porpoises within a certain distance from the sound source. To determine the 50% threshold received sound exposure level (SEL) of an…
Records of harbour porpoises (Phocoena phocoena) in fishing nets during the interwar period in Poland: Verification of archival materials
Psuty, Iwona
Aquatic Mammals (2013)
The Polish fisheries administration registered incidents of harbour porpoises caught by fishermen from fishing bases within the country's borders between 1922 and 1938. These data are unique in the Baltic…
Brief behavioral response threshold levels of a harbor porpoise (Phocoena phocoena) to five helicopter dipping sonar signals (1.33 to 1.43 kHz)
Kastelein, Ronald; Gransier, Robin; van den Hoogen, Marjan; Hoek, Lean
Aquatic Mammals (2013)
Helicopter Long Range Active Sonar (HELRAS) is deployed from navy helicopters to detect submarines. Its worldwide use by NATO navies is expected to increase due to the increasing need to…

Haelters, Jan; Kerckhof, Francis; Jauniaux, Thierry; Degraer, Steven;
Aquatic Mammals (2012)
In September 2011, two harbour porpoises (Phocoena phocoena) presenting extensive traumatic lesions washed ashore in Belgium. Similar lesions, with large parts of skin and blubber missing, had not been recorded…
An unusual mortality event of Harbor porpoises (Phocoena phocoena) off central California: Increase in blunt trauma rather than an epizootic

In 2007, the apparent increase in the number of harbor porpoises (Phocoena phocoena) stranding along the central California coast compared to the number of strandings the previous year resulted in…
The development of spatial positions between mother and calf of Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis) maintained in captive and seminatural environments
Xian, Yijie; Wang, Kexiong; Jiang, Wenhua; Zheng, Bangyou; Wang, Ding
Aquatic Mammals (2012)
For many toothed whales, two predominant and multifunctional spatial positions occur between a mother/calf pair after birth: (1) the echelon position and (2) the infant position. Other nonpredominant positions also…
