Application of Suction-cup-attached VHF Transmitters to the Study of Beluga, Delphinapterus leucas, Surfacing Behavior in Cook Inlet, Alaska [PDF]
Suction-cup-attached VHF radio transmittes were deployed on belugas, Delphinapterus leucas, in Cook Inlet, Alaska, in 1994 and 1995 to characterize the whales' surfacing behavior.

Timing is everything: Drivers of interannual variability in blue whale migration. [PDF]
Blue whales need to time their migration from their breeding grounds to their feeding grounds to avoid missing peak prey abundances, but the cues they use for this are unknown.

Predictions of southern migration timing in coastal sharks under future ocean warming
Abstract Projected redistribution of marine species due to ocean warming may undermine current conservation efforts. Yet, there have been few studies on how ocean warming may alter migration timing. Across 5 years of acoustic telemetry data (2018–2022), we determined environmental drivers of southward migration timing for 6 migratory shark species from

Botulism Type E Outbreak Associated with Eating a Beached Whale, Alaska
We report an outbreak of botulism that occurred in July 2002 in a group of 12 Alaskan Yu’pik Eskimos who ate blubber and skin from a beached beluga whale.

We present the first species‐specific epigenetic clock for common dolphins (Delphinus delphis), calibrated using dental ages from stranded and bycaught individuals. Despite concerns about dental ageing accuracy, our models showed strong performance and were unaffected by decomposition, supporting the use of post‐mortem samples for epigenetic clock ...

Optimizing Deep Learning Models with Improved BWO for TEC Prediction
The prediction of total ionospheric electron content (TEC) is of great significance for space weather monitoring and wireless communication. Recently, deep learning models have become increasingly popular in TEC prediction.

Migration phenology of beluga whales in a changing Arctic [PDF]
Global warming has been linked to dramatic environmental changes, particularly in polar marine environments, where water temperatures and sea-ice cover are especially affected. Using satellite telemetry, we investigated how local changes in sea-surface temperatures (2002−2004) affected the movement patterns of belugas Delphinapterus leucas in eastern ...

ABSTRACT The confluence of rivers with the ocean creates biological hotspots where temperature, salinity, and nutrients mix to provide excellent conditions for rearing, growth, and refuge to a multitude of organisms. Worldwide, estuaries are highly productive and biodiverse.
