Anisotropy in high-frequency broadband acoustic backscattering in the presence of turbulent microstructure and zooplankton
(2012-08)
High-frequency broadband (120-600 kHz) acoustic backscattering measurements have been made in the vicinity of energetic internal waves. The transducers on the backscattering system could be adjusted so as to insonify the ...
Acoustic scattering from density and sound speed gradients: Modeling of oceanic pycnoclines
(Published for the Acoustical Society of America through the American Institute of Physics, 2012-01)
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 ...
