Acoustic Signaling by Singing Humpback Whales (Megaptera novaeangliae): What Role Does Reverberation Play?
When humpback whales (Megaptera novaeangliae) sing in coastal waters, the units they produce can generate reverberation. Traditionally, such reverberant acoustic energy has been viewed as an incidental side-effect of high-amplitude, long-distance, sound transmission in the ocean. An alternative possibility, however, is that reverberation actually contributes to the structure and function of son...
متن کاملsonars and strandings: Are beaked Whales the Aquatic Acoustic Canary?
Introduction On the morning of 15 March, 2000, phones began ringing in Washington, Virginia, and Massachusetts. Emails flew between the USA and the Bahamas. The event behind these communications was a mass stranding of beaked whales (Ziphiidae) in the northern Bahamas extending from Grand Bahama to the tip of Abaco (Evans and England, 2001). Over two days, 17 whales were reported on shore, of w...
متن کاملPassive acoustic detection of deep-diving beaked whales.
Beaked whales can remain submerged for an hour or more and are difficult to sight when they come to the surface to breathe. Passive acoustic detection (PAD) not only complements traditional visual-based methods for detecting these species but also can be more effective because beaked whales produce clicks regularly to echolocate on prey during deep foraging dives. The effectiveness of PAD for b...
متن کاملLong-range acoustic tracking of Antarctic blue whales
The Southern Ocean Research Partnership (SORP) has developed an Antarctic Blue Whale Project which includes research to derive a mark-recapture abundance estimate for Antarctic blue whales. Tracking blue whales through passive acoustic monitoring has been identified as a potential means for increasing encounter rates, and thus facilitating abundance estimates through photo-identification and bi...
متن کاملEvidence for acoustic communication among bottom foraging humpback whales
Humpback whales (Megaptera novaeangliae), a mysticete with a cosmopolitan distribution, demonstrate marked behavioural plasticity. Recent studies show evidence of social learning in the transmission of specific population level traits ranging from complex singing to stereotyped prey capturing behaviour. Humpback whales have been observed to employ group foraging techniques, however details on h...
