Comparison and characteristics of oceanographic in situ measurements and simulations above submerged sand waves in a tidal inlet

Ocean colour and its transparency are related to turbidity caused by substances in water like organic and inorganic material. One of the essential climate variables (ECV) is ocean colour. However, this implies the correct interpretation of observed water quality parameters. Acoustic Doppler Current Profiler (ADCP) data of the three-dimensional current-field, echo intensity, modulation of suspended sediment concentration (SSC), and related water levels and wind velocities have been analysed as a function of water depth above submerged asymmetric compound sand waves during a tidal cycle in the Lister Tief of the German Bight in the North Sea.

ADCP | SSC – suspended sediment concentration | TSM – total suspended sediment | asymmetric compound sand wave | dynamic buoyancy density | action density
