  • von der Heydt, Keith; Eck, Calvert F. (Woods Hole Oceanographic Institution, 1995-05)
    During a recent experiment (April 1994), for the ONR Sea Ice Mechanics Initiative (SIMI), a portable data acquisition system was assembled that included 2 new developments. The first consists of a board, designed for the ...
  • Foote, Kenneth G. (Acoustical Society of America, 2012-05)
    Measurement of acoustic backscattering properties of targets requires removal of the range dependence of echoes. This process is called range compensation. For conventional sonars making measurements in the transducer ...
  • Walter, Maren; Mertens, Christian; Stober, Uwe; German, Christopher R.; Yoerger, Dana R.; Sultenfuß, Jurgen; Rhein, Monika; Melchert, Bernd; Baker, Edward T. (2010-08-23)
    The water column imprint of the hydrothermal plume observed at the Nibelungen field (8°18' S 13°30' W) is highly variable in space and time. The off-axis location of the site, along the southern boundary of a non-transform ...
  • Kukulka, Tobias; Plueddemann, Albert J.; Trowbridge, John H.; Sullivan, Peter P. (American Meteorological Society, 2010-11)
    Langmuir circulation (LC) is a turbulent upper-ocean process driven by wind and surface waves that contributes significantly to the transport of momentum, heat, and mass in the oceanic surface layer. The authors have ...
  • Traykovski, Peter A.; Geyer, W. Rockwell; Sommerfield, Christopher K. (American Geophysical Union, 2004-04-21)
    A 9 month time series of tripod-mounted optical and acoustic measurements of sediment concentration and bed elevation was used to examine depositional processes in relationship to hydrodynamic variables in the Hudson River ...
  • Sheen, K. L.; Brearley, J. A.; Naveira Garabato, Alberto C.; Smeed, D. A.; Waterman, Stephanie N.; Ledwell, James R.; Meredith, Michael P.; St. Laurent, Louis C.; Thurnherr, Andreas M.; Toole, John M.; Watson, Andrew J. (John Wiley & Sons, 2013-06-04)
    The spatial distribution of turbulent dissipation rates and internal wavefield characteristics is analyzed across two contrasting regimes of the Antarctic Circumpolar Current (ACC), using microstructure and finestructure ...
  • Foote, Kenneth G. (Acoustical Society of America, 1985-08)
    A new model describes acoustic scattering by swimbladdered fish of lengths from at least 8 to 36 wavelengths. It represents a fish by an ideal pressure‐release surface having the exact size and shape as the swimbladder. ...
  • Duda, Timothy F.; Bowlin, James B. (Acoustical Society of America, 1994-08)
    Using deterministic ray-acoustic modeling of 1000-km propagation in the North Pacific, a depth-dependent parameter of ocean sound channels has been found to strongly influence geometrical ray propagation. This parameter ...
  • Stanton, Timothy K.; Clay, Clarence S.; Chu, Dezhang (Acoustical Society of America, 1993-12)
    Data indicate that certain important types of marine organisms behave acoustically like weakly scattering fluid bodies (i.e., their material properties appear fluidlike and similar to those of the surrounding fluid medium). ...
  • Baumgartner, Mark F.; Fratantoni, David M.; Hurst, Thomas P.; Brown, Moira W.; Cole, Timothy V. N.; Van Parijs, Sofie M.; Johnson, Mark P. (Acoustical Society of America, 2013-08)
    In the past decade, much progress has been made in real-time passive acoustic monitoring of marine mammal occurrence and distribution from autonomous platforms (e.g., gliders, floats, buoys), but current systems focus ...
  • Lynch, James F.; Frye, Daniel E.; Peal, Kenneth R.; Liberatore, Stephen P.; Kery, Sean M.; Hobart, Edward; Newhall, Arthur E.; Smith, Stephen P. (Woods Hole Oceanographic Institution, 1992-06)
    A real-time tomography system has been developed which combines ocean acoustic tomography with satellite-based time keeping and satellite telemetry. The basis of the system is the acoustic tomography transceiver and its ...
  • Goldsmith, Roger A.; Richardson, Philip L. (Woods Hole Oceanographic Institution, 1987-11)
    An article in the November 1986 National Geographic magazine examined the question of Columbus's first landfall in the Americas. The author, Luis Marden, was the first to quantitatively include the effects of the winds ...
  • Zhu, Jian; Lin, Jian; Chen, Yongshun J.; Tao, Chunhui; German, Christopher R.; Yoerger, Dana R.; Tivey, Maurice A. (American Geophysical Union, 2010-09-21)
    Inversion of near-bottom magnetic data reveals a well-defined low crustal magnetization zone (LMZ) near a local topographic high (37°47′S, 49°39′E) on the ultraslow-spreading Southwest Indian Ridge (SWIR). The magnetic ...
  • Thomson, James M.; Elgar, Steve; Herbers, T. H. C. (American Geophysical Union, 2005-04-07)
    Ocean surface gravity waves with periods between 20 and 200 s were observed to reflect from a steep-walled submarine canyon. Observations of pressure and velocity on each side of the canyon were decomposed into incident waves ...
  • Tindle, Chris T.; Deane, Grant B.; Preisig, James C. (Acoustical Society of America, 2009-01)
    A tank experiment has been conducted to measure reflection of underwater sound from surface waves. Reflection from a wave crest leads to focusing and caustics and results in rapid variation in the received waveform as the ...
  • Thomson, James M.; Elgar, Steve; Herbers, T. H. C.; Raubenheimer, Britt; Guza, R. T. (American Geophysical Union, 2007-10-10)
    The propagation of infragravity waves (ocean surface waves with periods from 20 to 200 s) over complex inner shelf (water depths from about 3 to 50 m) bathymetry is investigated with field observations from the southern ...
  • Henderson, Stephen M.; Guza, R. T.; Elgar, Steve; Herbers, T. H. C. (American Meteorological Society, 2006-04)
    Previous field observations indicate that the directional spread of swell-frequency (nominally 0.1 Hz) surface gravity waves increases during shoreward propagation across the surf zone. This directional broadening contrasts ...

M.; Cianca, Andrés; Santana, R.; Llinas, Octavio; Rueda, María José; Mourino-Carballido, Beatriz (Copernicus Publications on behalf of the European Geosciences Union, 2012-08-01)
    We used 5-yr concomitant data of tracer distribution from the BATS (Bermuda Time-series Study) and ESTOC (European Station for Time-Series in the Ocean, Canary Islands) sites to build a 1-D tracer model conservation including ...
  • Nicholson, John W. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1988-08)
    This thesis presents the results of several experiments performed on side scan sonar equipment and imagery with the aim of characterizing the acoustic variability of side scan sonar imagery and applying this information ...
