Velocity data with LADCP

Please see the Data book for details of data.

Data process

 Vertical profiles of velocity are obtained by the inversion method (Visbeck, 2002).

 Visbeck, M. (2002): Deep velocity profiling using Lowered Acoustic Doppler Current Profilers: Bottom track and inverse solutions. J. Atmos. Oceanic Technol., 19, 794-807.
