Studies of Ocean Volume Reverberation at High Acoustic Frequencies
The principal goal of this research was to improve the ability of oceanographers to quantitatively measure small-to-intermediate scale spatial and temporal distributions of marine zooplankton, with size discrimination, in relation to the distribution of physical and chemical features in the ocean en...
