NTR: Request for ADCP bottom tracking from beams 1-4

[danibodc]

We received a request for new S04 terms to describe:
ADCP bottom tracking beam 1
ADCP bottom tracking beam 2
ADCP bottom tracking beam 3
ADCP bottom tracking beam 4

Bottom tracking is a technique to measure platform velocity relative to the seabed using the Doppler shift of an ADCP signal reflected off the seabed.

We will discuss with the requester if this is relevant for Doppler Velocity Logs as well as standard ADCP instruments.
