  • Lin, Ying-Tsong; Duda, Timothy F.; Lynch, James F. (Acoustical Society of America, 2009-10)
    Horizontal ducting of sound between short-wavelength nonlinear internal gravity waves in coastal environments has been reported in many theoretical and experimental studies. Important consequences arising at the open end ...
  • Badiey, Mohsen; Katsnelson, Boris G.; Lin, Ying-Tsong; Lynch, James F. (Acoustical Society of America, 2011-03-28)
    Simultaneous measurements of acoustic wave transmissions and a nonlinear internal wave packet approaching an along-shelf acoustic path during the Shallow Water 2006 experiment are reported. The incoming internal wave packet ...
  • Hunt, Mary M.; Marquet, William M.; Moller, Donald A.; Peal, Kenneth R.; Smith, Woollcott K.; Spindel, Robert C. (Woods Hole Oceanographic Institution, 1974-12)
    This report describes a system for underwater acoustic navigation developed, and in use, at the Woods Hole Oceanographic Institution. It includes a brief discussion of the electronic components, operation, mathematical ...
  • Foote, Kenneth G. (Acoustical Society of America, 1991-08)
    Knowledge of the acoustic sampling volume is necessary in many quantitative applications of acoustics. In general, the sampling volume is not merely a characteristic of the transmitting and receiving transducers, but also ...
  • Newhall, Arthur E.; Lynch, James F.; Gawarkiewicz, Glen G.; Duda, Timothy F.; McPhee, Neil M.; Bahr, Frank B.; Marquette, Craig D.; Lin, Ying-Tsong; Jan, Sen; Wang, Joe; Chen, Chi-Fang; Chiu, Linus Y. S.; Yang, Yiing Jiang; Wei, Ruey-Chang; Emerson, Chris; Morton, David; Abbot, Ted; Abbot, Philip A.; Calder, Brian; Mayer, Larry A.; Lermusiaux, Pierre F. J. (Woods Hole Oceanographic Institution, 2010-08)
    This document describes data, sensors, and other useful information pertaining to the ONR sponsored QPE field program to quantify, predict and exploit uncertainty in observations and prediction of sound propagation. This ...
  • Reeder, D. Benjamin (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2002-06)
    This thesis investigates the complexities of acoustic scattering by finite bodies in general and by fish in particular through the development of an advanced acoustic scattering model and detailed laboratory acoustic ...
  • Stanton, Timothy K.; Chu, Dezhang; Wiebe, Peter H.; Eastwood, Robert L.; Warren, Joseph D. (Acoustical Society of America, 2000-08)
    Acoustic backscattering measurements and associated scattering modeling were recently conducted on a type of benthic shelled animal that has a spiral form of shell (Littorina littorea). Benthic and planktonic shelled animals ...
  • Ross, Tetjana; Lavery, Andone C. (Acoustical Society of America, 2011-12-20)
    A weak-scattering model that allows prediction of acoustic scattering from oceanic pycnoclines (and the accompanying sound speed gradients) based on hydrographic profiles is described. Model predictions, based on profiles ...
  • Lavery, Andone C.; Ross, Tetjana (Acoustical Society of America, 2007-09)
    Laboratory measurements of high-frequency broadband acoustic backscattering (200–600 kHz) from the diffusive regime of double-diffusive microstructure have been performed. This type of microstructure, which was characterized ...
  • Dietzen, Gregory C. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2008-09)
    Benthic shells can contribute greatly to the scattering variability of the ocean bottom, particularly at low grazing angles. Among the effects of shell aggregates are increased scattering strength and potential subcritical ...
  • Jones, Benjamin A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2006-09)
    Blainville's beaked whales (Mesoplodon densirostris) use broadband, ultrasonic echolocation signals (27 to 57 kHz) to search for, localize, and approach prey that generally consist of mid-water and deep-water fishes and ...
  • Ray, Douglas S. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1993-08)
    Travel time perturbations of adiabatic normal modes due to an internal tide and internal mode field in the Barents Sea are examined. A formalism for the travel time perturbation due to a change in sound speed is presented. ...
  • Newman, Kori R.; Cormier, Marie-Helene; Weissel, Jeffrey K.; Driscoll, Neal W.; Kastner, Miriam; Solomon, Evan A.; Robertson, Gretchen; Hill, Jenna C.; Singh, Hanumant; Camilli, Richard; Eustice, Ryan M. (2007-11)
    Detailed near-bottom investigation of a series of giant, kilometer scale, elongate pockmarks along the edge of the mid-Atlantic continental shelf confirms that methane is actively venting at the site. Dissolved methane ...
  • Wage, Kathleen E. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1994-09)
    Normal mode theory provides an efficient description of signals which propagate axially in the SOFAR channel and are detectable at long ranges. Mode amplitudes and their second order statistics are useful in studies of ...
  • Preisig, James C. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1992-01)
    Adaptive array processing algorithms have achieved widespread use because they are very effective at rejecting unwanted signals (i.e., controlling sidelobe levels) and in general have very good resolution (i.e., have ...
  • Eickstedt, Donald Patrick (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2006-06)
    In this thesis, an innovative architecture for real-time adaptive and cooperative control of autonomous sensor platforms in a marine sensor network is described in the context of the autonomous oceanographic network scenario. ...
  • Li, Xingwen; Wunsch, Carl (American Geophysical Union, 2004-01-03)
    Adjoint sensitivities of CFC-11 concentrations and CFC-11/CFC-12 ratio ages in a North Atlantic general circulation model are analyzed. These sensitivities are compared with those of spiciness, T − (β/α) S, where α, β are ...
