Forward sound propagation around seamounts : application of acoustic models to the Kermit-Roosevelt and Elvis seamounts Kim, Hyun Joe (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2009-06)The Basin Acoustic Seamount Scattering Experiment (BASSEX) of 2004 was conducted to measure forward-scattering around the Kermit-Roosevelt Seamount Complex in the Northeast Pacific. The BASSEX experiment was focused on ...
Signell, Richard P. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1989-09)The dynamics of shallow tidal currents and tide-induced dispersion are investigated around coastal headlands that have alongshore length scales that are comparable to or less than the tidal excursion. Depth-averaged shallow ...
Macroscopic observations of diel fish movements around a shallow water artificial reef using a mid-frequency horizontal-looking sonar Lee, Wu-Jung; Tang, Dajun; Stanton, Timothy K.; Thorsos, Eric I. (Acoustical Society of America, 2018-09-18)The twilight feeding migration of fish around a shallow water artificial reef (a shipwreck) was observed by a horizontal-looking, mid-frequency sonar. The sonar operated at frequencies between 1.8 and 3.6 kHz and consisted ...
