Marine Mammal Science, EarlyView.ABSTRACT In 2024, an expedition was conducted off northwestern Baja California, México, to find and identify the beaked whale species that produced the BW43 echolocation pulse previously recorded in this area and elsewhere in the North Pacific. There were five Mesoplodon sightings and 21 BW43 acoustic detections on both a towed array and drifting pole ...

The Truth About Soviet Whaling [PDF]
, 2008 I have always condemned (and to do anything more was not within our power or abilities) the illegal and sometimes destructive whaling by the Soviet Union.

Seasonal Abundance and Distribution of Cetaceans in a High Traffic Shipping Corridor
Marine Mammal Science, EarlyView.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 ...

MONICEPH project: Monitoring cephalopods during whale-watching activity in the Azores (2020-2024) [PDF]
Biodiversity Data JournalThe study of oceanic cephalopods off the Azores Archipelago began decades ago with the analysis of stomach contents from sperm whales that were hunted for the whaling industry.

Marine Mammal Science, EarlyView.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 ...

Marine Mammal Science, EarlyView.ABSTRACT Acoustic monitoring is an essential tool for investigating animal communication and behavior when visual contact is limited, but the scalability of bioacoustic projects is often limited by time‐intensive manual auditing of focal signals. To address this bottleneck, we introduce orcAI—a novel deep learning framework for the automated detection ...

Experimental Physiology, EarlyView.Abstract High‐resolution movement data from Cuvier's beaked, or goose‐beaked whale (Ziphius cavirostris, hereafter Ziphius, n = 8) tag deployments (4.1–19.2 days) were used to estimate blood and tissue O2 and CO2 levels. Acceleration and magnetometry data were used to estimate the locomotion cost (LC) from the relationship between activity and the O2 ...

Soviet Illegal Whaling: The Devil and the Details [PDF]
, 2011 In 1948, the U.S.S.R. began a global campaign of illegal whaling that lasted for three decades and, together with the poorly managed “legal” whaling of other nations, seriously depleted whale populations.
