Marine acoustic ecologies and acoustic habitats: Concepts, metrics, and realitiesChristopher W Clark
Bioacoustics Res Prog, Cornell Univ, 159 Sapsucker Woods Rd, Ithaca, NY 14850
J Acoust Soc Am 130:2320. 2011..From a large-scale, ecological perspective, these acoustic habitat reductions likely represent significant costs for species for which acoustic communication is biologically critical...- Calibration and comparison of the acoustic location methods used during the spring migration of the bowhead whale, Balaena mysticetus, off Pt. Barrow, Alaska, 1984-1993C W Clark
Cornell Lab of Ornithology, Bioacoustics Research Program, Ithaca, New York 14850, USA
J Acoust Soc Am 107:3509-17. 2000..At these ranges in shallow water, signal propagation appears to be dominated by the fundamental mode and is not corrupted by multipath... 
Acoustic monitoring on a humpback whale (Megaptera novaeangliae) feeding ground shows continual singing into late SpringChristopher W Clark
Bioacoustics Research Program, Laboratory of Ornithology, Cornell University, 159 Sapsucker Woods Road, Ithaca, NY 14850, USA
Proc Biol Sci 271:1051-7. 2004..Singing at these times represents either low-cost opportunistic advertising by (perhaps relatively few) males to court females that failed to conceive during the winter, and/or possibly an intrasexual display...- Acoustic detection of North Atlantic right whale contact calls using spectrogram-based statisticsIldar R Urazghildiiev
Bioacoustics Research Program, Cornell Laboratory of Ornithology, Ithaca, New York 14850 1999, USA
J Acoust Soc Am 122:769-76. 2007..The test results demonstrate that in the presence of impulsive noise, the spectrogram-based detector using the French hat wavelet as the filter kernel outperforms the GLRT detector and decreases computational time by a factor of 6... - Detection performances of experienced human operators compared to a likelihood ratio based detectorIldar R Urazghildiiev
Bioacoustics Research Program, Cornell Laboratory of Ornithology, Ithaca, New York, 14850 1999, USA
J Acoust Soc Am 122:200-4. 2007..Test results demonstrate that, for a given human operator false alarm probability, the GLRT-based detector provided a higher probability of detecting signals than human operators... 
Acoustically detected year-round presence of right whales in an urbanized migration corridorJanelle L Morano
Bioacoustics Research Program, Cornell Lab of Ornithology, Cornell University, Ithaca, NY 14850, USA
Conserv Biol 26:698-707. 2012....- Underwater, low-frequency noise in a coastal sea turtle habitatY Samuel
Department of Earth and Atmospheric Sciences, Ocean Resources and Ecosystems Program, Cornell University, Ithaca, New York 14853, USA
J Acoust Soc Am 117:1465-72. 2005..Results suggest that continued exposure to existing high levels of pervasive anthropogenic noise in vital sea turtle habitats and any increase in noise could affect sea turtle behavior and ecology... - Behavioral responses of humpback whales (Megaptera novaeangliae) to full-scale ATOC signalsA S Frankel
Cornell Bioacoustics Research Program, Ithaca, New York 14850, USA
J Acoust Soc Am 108:1930-7. 2000..The repeatability of the findings for these two different studies indicates that these effects, while small, are robust. This suggests that at least for the ATOC signal, the received sound level is a good predictor of response... - Variation in humpback whale (Megaptera novaeangliae) song length in relation to low-frequency sound broadcastsKurt M Fristrup
Bioacoustics Research Program, Cornell Laboratory of Ornithology, Ithaca, New York 14853, USA
J Acoust Soc Am 113:3411-24. 2003..Humpbacks responded to louder broadcasts with longer songs. The fraction of variation in song length that could be attributed to broadcast factors was low. Much of the variation in humpback song length remains unexplained... - Blue whale (Balaenoptera musculus) sounds from the North AtlanticDavid K Mellinger
Bioacoustics Research Program, Cornell University, 159 Sapsucker Woods Road, Ithaca, New York 14850 1999, USA
J Acoust Soc Am 114:1108-19. 2003.... - Seasonal and geographical patterns of fin whale song in the western North Atlantic OceanJanelle L Morano
Bioacoustics Research Program, Cornell Lab of Ornithology, Cornell University, Ithaca, New York 14850, USA
J Acoust Soc Am 132:1207-12. 2012..Short-INI and high note abundance correspond to the fin whale reproductive season. The temporal variability of INI may be a mechanism by which fin whale individuals encode and communicate a variety of behaviorally relevant information... - Acoustic detection of North Atlantic right whale contact calls using the generalized likelihood ratio testIldar R Urazghildiiev
Bioacoustics Research Program, Cornell Laboratory of Ornithology, Ithaca, New York 14850 1999, USA
J Acoust Soc Am 120:1956-63. 2006..The curves demonstrate that the proposed detector provides superior detection performance as compared with other known detection techniques for northern right whale contact calls... - Short- and long-term changes in right whale calling behavior: the potential effects of noise on acoustic communicationSusan E Parks
Bioacoustics Research Program, Cornell Laboratory of Ornithology, 159 Sapsucker Woods Road, Ithaca, New York 14850, USA
J Acoust Soc Am 122:3725-31. 2007.... - Only male fin whales sing loud songsDonald A Croll
Department of Ecology and Evolutionary Biology, Center for Ocean Health, University of California, Santa Cruz, California 95060, USA
Nature 417:809. 2002..This finding indicates that they may function as male breeding displays, and will help to focus concern on the impact of human-generated low-frequency sounds on recovering whale populations... - Ecology. North Atlantic right whales in crisisScott D Kraus
