First recorded ice entrapment of a beluga whale (Delphinapterus leucas) in east Greenland
Polar ResearchBeluga whales are rare along the coast of east Greenland and the closest recognized stock occurs around Svalbard. Here we report on an ice entrapment of an adult beluga whale (Delphinapterus leucas) in north-east Greenland.

Perceptually Motivated Wavelet Packet Transform for Bioacoustic Signal Enhancement [PDF]
, 2008 A significant and often unavoidable problem in bioacoustic signal processing is the presence of background noise due to an adverse recording environment. This paper proposes a new bioacoustic signal enhancement technique which can be used on a wide range

Range contraction in a beluga whale population [PDF]
Endangered Species Research, 2010 The small, isolated population of beluga whales Delphinapterus leucas in Cook Inlet, Alaska, USA, has had a distinct contraction in range over the past 3 decades. This contraction is a function of a decline in abundance, evidently caused, at least in part, by high takes during unregu- lated subsistence hunting.

Lateralized sound production in the beluga whale (Delphinapterus leucas) [PDF]
Journal of Experimental Biology, 2020 Like other toothed whales, belugas produce sound through pneumatic actuation of two phonic lip pairs, but it is unclear whether both pairs are actuated concurrently to generate a single sound (the dual actuation hypothesis) or laterally in the production of their rich vocal repertoires.

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 ...
