  • Three-dimensional beam pattern of regular sperm whale clicks confirms bent-horn hypothesis 

    Zimmer, Walter M. X.; Tyack, Peter L.; Johnson, Mark P.; Madsen, Peter T. (Acoustical Society of America, 2005-03)
    The three-dimensional beam pattern of a sperm whale (Physeter macrocephalus) tagged in the Ligurian Sea was derived using data on regular clicks from the tag and from hydrophones towed behind a ship circling the tagged ...
  • Echolocation clicks of free-ranging Cuvier's beaked whales (Ziphius cavirostris) 

    Zimmer, Walter M. X.; Johnson, Mark P.; Madsen, Peter T.; Tyack, Peter L. (Acoustical Society of America, 2005-06)
    Strandings of beaked whales of the genera Ziphius and Mesoplodon have been reported to occur in conjunction with naval sonar use. Detection of the sounds from these elusive whales could reduce the risk of exposure, but ...
  • Off-axis effects on the multipulse structure of sperm whale usual clicks with implications for sound production 

    Zimmer, Walter M. X.; Madsen, Peter T.; Teloni, Valeria; Johnson, Mark P.; Tyack, Peter L. (Acoustical Society of America, 2005-11)
    Sperm whales (Physeter macrocephalus) produce multipulsed clicks with their hypertrophied nasal complex. The currently accepted view of the sound generation process is based on the click structure measured directly in front ...
  • Modeling acoustic propagation of airgun array pulses recorded on tagged sperm whales (Physeter macrocephalus) 

    DeRuiter, Stacy L.; Tyack, Peter L.; Lin, Ying-Tsong; Newhall, Arthur E.; Lynch, James F.; Miller, Patrick J. O. (Acoustical Society of America, 2006-12)
    In 2002 and 2003, tagged sperm whales (Physeter macrocephalus) were experimentally exposed to airgun pulses in the Gulf of Mexico, with the tags providing acoustic recordings at measured ranges and depths. Ray trace and ...
