Relatively little is known about the distribution and diversity of marine mammals around offshore anthropogenic structures. We present results obtained from incidental sightings of marine mammals around oil and gas…
Effects of constructing the DanTysk offshore wind farm (German Bight, 80 turbines, 6 m diameter foundations) were studied by passive acoustic monitoring of pile-driving noise and harbour porpoise Phocoena phocoena…
Many countries have made statutory commitments to ensure that underwater noise pollution is at levels which do not harm marine ecosystems. Nevertheless, coordinated action to manage cumulative noise levels is…
- This is a conservation plan for the Harbour Porpoise Phocoena phocoena based on the current seasonal occurrence and abundance of porpoises within waters under Dutch jurisdiction. - The conservation…
Harbor porpoises (Phocoena phocoena) were rarely seen in San Francisco Bay prior to 2008 despite numerous marine mammal search efforts beginning in the 1970s. The species inhabited the bay historically…
Exploitation of renewable energy from offshore wind farms is substantially increasing worldwide. The majority of wind turbines are bottom mounted, causing high levels of impulsive noise during construction. To prevent…
Poyang Lake, located in the middle and lower reaches of the Yangtze River, is the largest freshwater lake in China and the most important habitat for the Yangtze finless porpoise.…
Under the EU Habitats Directive, cetacean species must be maintained at favourable conservation status in European waters. Whether this is achieved via protected area designation, curtailment of activities such as…
Marine renewable energy (MRE) developments often coincide with sites frequented by small cetaceans. To understand habitat use and assess potential impact from development, echolocation clicks were recorded with acoustic click…
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…
