| Title | Acoustic data of multi-frequency acoustic system(UM0708) |
| Sub-Title | Vartical profiles of volume backscattering strength |
| Data Summary | Vertical profiles of volume backscattering strength recorded by multi-frequency acoustic system for estimate size-abundance spectra of small zooplankton. The system was horizontally mounted on CTD frame and the observation was vertically performed from surface to 200 m at 23 stations. |
