Query: Correction of Teledyne Acoustic Doppler Current Profiler (ADCP)
  Bottom-Track Range Measurements for Instrument Pitch and Roll   The Workhorse Acoustic Doppler Current Profiler (ADCP) manufactured by
Teledyne RD Instruments (RDI) uses a "Bottom-Tracking" algorithm to yield data
intended to represent distance to the bottom. However, current RDI software
processing does not take into account the pitch and roll of the instrument.
This technical note outlines post-deployment computations required to correct
the reported Bottom-Track Ranges for instrument pitch and roll in the scenario
where the ADCP is upward-looking with Bottom-Tracking being used to estimate
distance to the surface.
