Acoustic data of multi-frequency acoustic system
Listed in NASA Earthdata CMR
Vertical profiles of volume backscattering strength recorded by multi-frequency acoustic system for estimate size-abundance spectra of small zooplankton.
Description
The system was horizontally mounted on CTD frame and the observation was vertically performed from surface to 200 m at 23 stations.
