Abstract Harbour porpoises frequently alter their behaviour in response to underwater sound from shipping, seismic surveys, drilling and marine renewables. Less well understood is the response of porpoises to sounds emitted from oil and gas (O&G) platforms during routine operations. The responses are not easily predicted as platforms can act simult...

Monitoring, understanding, and communicating the impact of offshore oil and gas exploration and production (E&P) activities on marine mammal (MM) biodiversity can be challenging. Here, we share methods, results, and experiences accumulated during seven years of monitoring MM and underwater sound in a mature E&P activity area in the North-East Atlan...

The harbour seal (Phoca vitulina, L 1758) is the most common Danish seal species and can be found in most Danish waters. It is frequently observed in rivers and streams all around the Northern Hemisphere. Harbour seals naturally swim up large freshwater streams in search for food. This has caused conflicts with anglers fishing for trout and salmon,...

The most common cetacean in the North Sea is the harbor porpoise (Phocoena phocoena). Underwater noise is increasingly recognized as a source of impact on the marine environment and seismic airguns were one of the first man-made high intensity sound source to receive attention with respect to potential impact on marine mammals. In this study, we in...
Article
Full-text available
Knowledge about the impact of anthropogenic disturbances on the behavioural responses of cetaceans is constrained by lack of data on fine-scale movements of individuals. We equipped five free-ranging harbour porpoises (Phocoena phocoena) with high-resolution location and dive loggers and exposed them to a single 10 inch3 underwater airgun producing...

In 2017 an emergency field effort was undertaken in an attempt to prevent the extinction of the world's most endangered marine mammal, the vaquita Phocoena sinus. The rescue effort involved 90 experts from 9 countries and cost US$ 5 million. Following a long decline due to entanglement in legal gillnet fisheries, the vaquita population had fallen f...
Article
Gaining knowledge about the biodiversity of an area is a prerequisite to understanding and protecting the inhabiting species. Very little is known about cetacean species and their distribution in Qatar marine waters. The Al Shaheen offshore oil extraction platforms situated in the Arabian Gulf 85 km NE of Qatar mainland have been identified as a ho...
Article
Acoustic harassment and deterrent devices have become increasingly popular mitigation tools for negotiating the impacts of marine mammals on fisheries. The rationale for their variable effectiveness remains unexplained, but high variability in the surrounding acoustic field may be relevant. In the present study, the sound fields of one acoustic har...
