Benchmark datasets for velocity measurements

From Atomix

These datasets are currently located in Zenodo. They will eventually be housed at the BODC center.


Summary of potential benchmark datasets for testing existing and future algorithms
Dataset name Total depth Deployment distance from boundary Background median speed ε range Stratification/shear information Comment
Units [m] [m] [m/s] [W/kg]
Tidal Slough ADV 2.8 0.45 0.15 1e-7 to 1e-5 Unstratified, but shear-induced anisotropy Viscous subrange is occasionally resolved. Another ADV at 0.15 m shows wrapping issues.
Tidal Shelf ADV 250 0.4 0.26 1e-7 to 1e-4 Stratified bottom log-layer High-quality dataset with phase wrapping. It overlaps with an ADCP Signature benchmark.
Underice MAVS 353 5 0.03 3e-9 to 7e-8 Weak stratification Under-ice boundary layer, MAVS suspended 5 m beneath the ice
Tidal MAVS 20 1.45 1.1 3e-4 to 1e-3 Weak stratification Strong tidal flows
