Journal ArticleDOI
Increases in deep ocean ambient noise in the Northeast Pacific west of San Nicolas Island, California.
TL;DR: Recent measurement at a previously studied location illustrates the magnitude of increases in ocean ambient noise in the Northeast Pacific over the past four decades.
Journal ArticleDOI
Kinematics of foraging dives and lunge-feeding in fin whales
Jeremy A. Goldbogen,Jeremy A. Goldbogen,John Calambokidis,Robert E. Shadwick,Erin M. Oleson,Mark A. McDonald,John A. Hildebrand +6 more
TL;DR: Examination of body kinematics at depth reveals variable lunge-feeding behavior in the context of distinct kinematic modes, which exhibit temporal coordination of rotational torques with translational accelerations.
Journal ArticleDOI
Behavioral context of call production by eastern North Pacific blue whales
Erin M. Oleson,John Calambokidis,William C. Burgess,Mark A. McDonald,Carrie A. LeDuc,John A. Hildebrand +5 more
TL;DR: The relationship between calling and depth may predict the traveling behavior of singing blue whales, as traveling whales do not typically dive to deep depths and therefore would experience little extra energetic cost related to the production of long repetitive song bouts while moving between foraging areas.
Journal ArticleDOI
Blue and fin whales observed on a seafloor array in the Northeast Pacific
TL;DR: Call tracks, call patterns, call character, and swimming speeds were examined during periods with and without the presence of noise, and whale responses associated with these noises remain arguable.
Journal ArticleDOI
Seasonality of blue and fin whale calls and the influence of sea ice in the Western Antarctic Peninsula
TL;DR: In this article, the seasonality of whale calls was assessed using acoustic data recorded on seven autonomous acoustic recording packages (ARPs) deployed from March 2001 to February 2003 in the Western Antarctic Peninsula.
