Distribution and density of harbour popoises in Dutch North Sea waters [PDF]
, 2009 Aerial surveys were conducted to investigate harbour porpoise density and distribution in Dutch waters. Surveys were conducted following standard line transect distance sampling methodology on tracklines providing a representative coverage of the study ...

Mammal Review, Volume 56, Issue 1, March 2026.Marine mammals are vulnerable to a variety of anthropogenic threats, yet a global systematic map of the literature for 19 species found both spatial and temporal disparity in research effort between threats and between species. There are knowledge gaps for species and threats, with effort unequal across many species' ranges.

Harbour porpoises (Phocoena phocoena) in the North Atlantic: Biological parameters
NAMMCO Scientific Publications, 2003 Biological parameters for harbour porpoises are reviewed throughout their range in the North Atlantic. Most information is based on studies of a combination of directed catches, bycatches and strandings.

Patterns of variability of retinol levels in a harbour porpoise population from an unpolluted environment [PDF]
, 1999 Organochlorine compounds (OC) are known to induce vitamin A (retinoids) deficiency in mammals, which may be associated with impairment of immunocompetence, reproduction and growth.

Evaluating the Risk of Collision of Seals Swimming Within Metres of Operating Tidal Turbines
Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.ABSTRACT We used imaging sonar to continuously monitor wildlife at an operational tidal turbine in the Pentland Firth, Scotland, between May 2022 and June 2023. Of 704 detected seal tracks, 347 occurred during turbine operation and 122 of these were detected directly upstream of the rotating blades in the horizontal plane.

Quantifying harbour porpoise foraging behaviour in CPOD data [PDF]
Proceedings of Meetings on Acoustics, 2019 Harbour porpoises (Phocoena phocoena) are regularly monitored to assess how they are impacted by the construction and operation of offshore wind farms. A suitable method to do this is passive acoustic monitoring (PAM) by stationary hydrophones, for example CPODs.

Bycatch as a potential threat to harbour porpoises (Phocoena phocoena) in Polish Baltic waters
NAMMCO Scientific Publications, 2003 Sixty-two verified reports obtained in the years 1990-1999 on the bycatch, strandings and sightings of harbour porpoises in the Polish Baltic were analysed in this study. In relative terms the highest number of reports (22) was noted in Puck Bay.

Ecology and Evolution, Volume 16, Issue 2, February 2026.The Indo‐Pacific humpback dolphin population in Xiamen Bay was divided into two geographically separated but socially associated communities inhabiting the West and East sub‐regions. Based on 3 years of boat‐based surveys, this study established baseline acoustic characteristics and investigated whether vocal patterns varied with habitat conditions ...
