Observations include both stationary bottom-mounted deployments and vessel-based transects, enabling resolution of flow variability across tidal cycles and spatial gradients. Upward-looking ADCP instruments recorded time series of three-dimensional velocity profiles, pressure, and instrument orientation, which were subsequently processed into Earth-referenced velocity components and tidal elevation estimates. Complementary transect surveys captured depth-averaged flow structure and hydrographic parameters along repeated cross-sections.\n\nPost-processing workflows included quality control, coordinate transformations, and derivation of secondary products such as streamwise and cross-stream velocities using principal component analysis. The resulting dataset provides a consistent representation of current magnitude, direction, and vertical structure under ebb and flood conditions.\n\nThese measurements support improved understanding of tidal flow dynamics around engineered structures, with possible applications to sediment transport, structural loading, and environmental assessment analyses. The combined fixed and mobile observational approach offers a comprehensive framework for resolving both temporal variability and spatial heterogeneity in coastal and shelf environments.\n\nFor
