Echolocation, the main sensory modality of odontocetes and microbats, has mostly been studied using single receivers. Such a recording setup is sufficient to study signal parameters like pulse interval, inter…
The harbour porpoise (Phocoena phocoena) is widely distributed in shelf waters of the temperate North Atlantic and North Pacific Oceans and in some semi-enclosed seas (e.g. the Black, Baltic Seas…
This is the ASCOBANS species action plan for what is called Baltic harbour porpoise population primarily inhabiting the Baltic Proper. The population’s abundance has recently been estimated at only 497…
The monitoring program on harbour porpoises at Horns Rev Offshore Wind Farm in the Danish North Sea, initiated in 1999, has now come to an end with collection of final…
A decade of visual and acoustic detections of marine megafauna around offshore Oil & Gas (O&G) installations in the North and Irish Seas are presented. Marine megafauna activity was monitored…
In Georgian territorial waters of the Black Sea, three leucistic harbour porpoises and one piebald short beaked common dolphin were spotted during the years 2012-2016. All images of the specimens…
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…
Stomach content composition and prey-specific consumption rates of juvenile and adult harbor porpoises (Phocoena phocoena) were estimated from a data set including 339 stomachs collected over a 32 yr period…
The mechanism by which odontocetes produce sound is unique among mammals. To gain insight into the physiological properties that support sound production in toothed whales, we examined myoglobin content ([Mb]),…
Pile driving of large steel monopiles in offshore waters has increased rapidly in recent years due to the expanding development of offshore wind energy. In particular, Phocoena phocoena (harbor porpoise)…
