Comparing the performance of C-PODs and SoundTrap/PAMGUARD in detecting the acoustic activity of harbor porpoises (Phocoena phocoena). [PDF]
, 2016 The C-POD logger is a widely used instrument for passive acoustic monitoring of harbor porpoises, but the absence of a continuous recording in this device makes it difficult to verify its performance.

Seasonal Abundance and Distribution of Cetaceans in a High Traffic Shipping Corridor
Marine Mammal Science, Volume 42, Issue 1, January 2026.ABSTRACT The recovery of many cetacean species coincides spatially and temporally with intensifying anthropogenic threats. We undertook multi‐year systematic surveys to quantify seasonal abundance and document the distribution of at‐risk cetaceans, which is needed to assess the impacts of increasing human activities in the Canadian portions of the ...

Marine Mammal Science, Volume 42, Issue 1, January 2026.ABSTRACT The Mediterranean common dolphin (Delphinus delphis) presents an enigmatic natural history during the past centuries. Widely prevalent in the 19th and early 20th centuries, it faced a significant decline across most of the basin by the late 1960s caused by multiple anthropogenic threats, including culling, bycatch, prey depletion, and habitat ...

Predicting the impacts of anthropogenic disturbances on marine populations [PDF]
, 2018 Marine ecosystems are increasingly exposed to anthropogenic disturbances that cause animals to change behavior and move away from potential foraging grounds. Here we present a process-based modeling framework for assessing population consequences of such

Marine Mammal Science, Volume 42, Issue 1, January 2026.ABSTRACT Monitoring live and stranded cetaceans can be expensive and logistically challenging, resulting in knowledge gaps. Very high‐resolution (VHR) optical satellites are considered a potential solution to addressing some of these gaps. Despite success at detecting live and stranded cetaceans, satellites have only been trialed on restricted ...

Contaminant analyses of harbor porpoises
, 2021 Altogether, 22 porpoises were analyzed for organochlorines (PCBs DDTs, HCHs, HCB), PBDEs, HBCDD and CPs in blubber, and 23 porpoises for PFAS and OTCs in liver, and metals and Se in muscle and liver, and SI (d13C and d15N) in muscle. The animals were divided into four groups: animals originating from the North Sea Population area (juveniles and adults)

Integrating Porpoise and Cod Management: A Comparison of Days-at-sea, ITQs, and Closures [PDF]
The purpose of this study is to determine if management measures based on effort reductions, in particular days-at-sea (DAS) controls, can approach a harbor porpoise individual transferable quotas (ITQ) program in terms of efficiency.

Histological investigations on the thyroid glands of marine mammals (Phoca vitulina, Phocoena phocoena) and the possible implications of marine pollution [PDF]
, 1993 In 1988 and 1989, thousands of harbor seals (Phoca vitulina) died in the North Sea from phocine distemper infection. The morphology of thyroid glands from 40 harbor seals found dead on the North Sea coastlines of Schleswig-Holstein, Federal Republic of ...
