First Evidence of Retrospective Findings of Microplastics in Harbour Porpoises (Phocoena phocoena) From German Waters

Frontiers in Marine Science, 2021
Microplastic ingestion by lower trophic level organisms is well known, whereas information on microplastic ingestion, egestion and accumulation by top predators such as cetaceans is still lacking.

Scalable low‐cost seabed landers: the missing link for sustained, integrated, long‐term observations in dynamic shallow seas

Remote Sensing in Ecology and Conservation, EarlyView.
Seabed landers, when equipped with a range of biotic and abiotic sensors, offer a non‐invasive and cost‐effective solution for ecosystem‐scale monitoring of Essential Biodiversity Variables (EBVs) and Essential Ocean Variables (EOVs) in dynamic shallow seas.

Assessing the Underwater Impact of Aerodynamic Noise From Offshore Wind Turbines

Wind Energy, Volume 29, Issue 7, July 2026.
ABSTRACT The growing demand for offshore wind energy has led to a significant increase in wind turbine size and to the development of large‐scale wind farms, often comprising 100–150 turbines. However, the environmental impact of underwater noise emissions remains largely unaddressed.

Echosounders for fish detection disturb harbour porpoises

Environmental Pollution
Abstract The marine world is an acoustic world that has become noisier with the increasing diversity and intensity of human activities at sea. The harbour porpoise ( Phocoena phocoena ) is one of the best-studied cetaceans regarding hearing and responses to human-made underwater ...

Reading between the lines: Novel insights on wild Pacific harbour porpoise (Phocoena phocoena vomerina) social communication through narrow-band high frequency click trains.

PLoS ONE
For cetaceans that produce narrow-band high-frequency click trains such as the Pacific harbour porpoise (Phocoena phocoena vomerinae), social acoustic behavior is poorly understood.

The relationship between developmental stability, Ggenomic diversity and environmental stress in two cetacean species:: the Harbour Porpoise (Phocoenaphocoena) and The Bottlenose Dolphin (Tursiops truncatusl) [PDF]

, 2005
The relationship between developmental stability, genomic diversity and environmental stress in three eastern North Atlantic populations of the harbour porpoise {Phocoena phocoena), and in two populations of the western North Atlantic and one from the ...

Follow-up study after four years shows reduced deterrence effect of pingers on harbour porpoises in Norwegian gillnet fishery

NAMMCO Scientific Publications
We report results from follow-up field trials testing acoustic deterrents (pingers) as a measure to reduce harbour porpoise (Phocoena phocoena) by-catch rates in coastal gillnet fisheries in Norway.

Harbor Porpoise and Beluga Whale Habitat Use in the Saguenay‐St. Lawrence Marine Park (Canada) Revealed by a Combination of Visual and Acoustic Survey

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Studying habitat use of cetaceans that spend most of their lives underwater poses challenges, prompting the use of complementary methods. Non‐invasive methods, land‐based surveys (LBS) and passive acoustic monitoring (PAM), were used to characterize occurrence patterns of beluga whales, harbor porpoises, and vessels in the Saguenay–St ...

Habitat characteristics of the shelf distribution of the harbour porpoise (Phocoena phocoena) in the waters around the Faroe Islands during summer

NAMMCO Scientific Publications, 2003
Observations from a large number of seabird line-transect surveys conducted in Faroese waters are used to derive some general conclusions regarding the distribution of harbour porpoises (Phocoena phocoena) in the region using estimates of encounter rates
