The bin length is the time interval over which the velocity estimate is calculated. Range-gating the acoustic return as a function of time yields a vertical profile of velocity. We collect 60 depth bins. The shallowest measurement depth is 16 m. Maximum depth of good data return is about 300 m. Actual sound speed is calculated from measured temperature at the transducer and a constant salinity of 33 psu.
