Acoustic interaction of humpback whales and whale-watching boats

Marine Environmental Research, 2000
The underwater acoustic noise of five representative whale-watching boats used in the waters of west Maui was measured in order to study the effects of boat noise on humpback whales. The first set of measurements were performed on 9 and 10 March, close to the peak of the whale season.

Visualizing the underwater behavior of humpback whales

IEEE Computer Graphics and Applications, 2006
A new collaboration between visualization experts, engineers, and marine biologists has changed. For the first time, we can see and study the foraging behavior of humpback whales. Our study's primary objective was furthering the science of marine mammal ethology.

Humpback whale sonar

The Journal of the Acoustical Society of America, 1996
During the winter months male humpback whales produce long complex sequences of sounds which have been described as song. Current hypotheses for the function of humpback whale song speculate that it serves primarily to provide other whales with information about the singer such as location and reproductive fitness.

Information entropy of humpback whale song

The Journal of the Acoustical Society of America, 1999
Many theories of nonhuman animal communication posit a first-order Markov model in which the next signal depends only on the current one. Such a model precludes a hierarchical structure to the communication signal. Information theory and signal processing provide quantitative techniques to estimate the underlying complexity of an arbitrary signal or ...

Songs of Humpback Whales

Science, 1971
1) Humpback whales ( Megaptera novaeangliae ) produce a series of beautiful and varied sounds for a period of 7 to 30 minutes and then repeat the same series with considerable precision. We call such a performance "singing" and each repeated series of sounds a "song." 2) All prolonged sound ...

Acoustic properties of humpback whale songs

The Journal of the Acoustical Society of America, 2006
A vertical array of five hydrophones was used to measure the acoustic field in the vertical plane of singing humpback whales. Once a singer was located, two swimmers with snorkel gear were deployed to determine the orientation of the whale and position the boat so that the array could be deployed in front of the whale at a minimum standoff distance of ...

Sound production by singing humpback whales

The Journal of the Acoustical Society of America, 2010
Sounds from humpback whale songs were analyzed to evaluate possible mechanisms of sound production. Song sounds fell along a continuum with trains of discrete pulses at one end and continuous tonal signals at the other. This graded vocal repertoire is comparable to that seen in false killer whales [Murray et al. (1998). J. Acoust. Soc. Am.

Humpback whale song or humpback whale sonar? A reply to Au et al

IEEE Journal of Oceanic Engineering, 2001
Au et al.'s arguments against the hypothesis that humpback whale songs function as long-range sonar are based on questionable assumptions rather than on empirical data. Like other echolocating mammals (e.g., bats), singing humpback whales: 1) localize targets in the absence of visual information; 2) possess a highly innervated peripheral auditory ...
