Deep Scattering Layer Observation by Acoustic Correlation Current Profiler

Acoustic correlation current profiler (ACCP) was proposed to observe deep scattering layer (DSL). Several important parameters of ACCP could be used to observe DSL, such as the strength of the backscattering, the vertical velocity of current profile and the cross correlation function. Based on these parameters, 23 kHz prototype ACCP was used to observe DSL in sea trials in South China Sea. Results showed that it was feasible to observe DSL by ACCP.
