Applying Mass Conservation to ADCP-data
Summary
Adding mass constraints to existing ADCP-data results in improved velocity estimates in various
transducer configurations. The problem of estimating vertical velocity with a conventional set-up
in horizontally dominant flow is that inhomogenities in the horizontal velocities can cause relatively
large errors in the vertical velocity estimate. A possible solution to obtain more accurate vertical
velocity estimates using mass constraints is introduced. The corrected data is compared to the original uncorrected data. Then a novel configuration of transducers that is a combination of multiple
transducer-receivers in a buckyball set up is discussed. Mass constraints are applied to synthetic data
of this set up, and this leads in various circumstances to improved estimates. Also discussed is a proof
of concept showing the ability of this set up to measure the shearing motion of internal waves.
