Benchmark datasets for velocity measurements: Difference between revisions

Revision as of 16:22, 4 May 2026

These datasets are temporarily in a folder, and will eventually be housed at the BODC center with a DOI.

Summary of potential benchmark datasets for testing existing and future algorithms
Dataset name	Total depth	Deployment height above bottom	Background speed	$ε$ range	Stratification/shear information	Comment
Units	[m]	[m]	[m/s]	[W/kg]
Tidal Slough ADV	2.8	0.45	0.15-0.2	1e-8 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	<0.65	1e-7 to 1e-5	Stratified bottom log-layer	High-quality dataset with phase wrapping. It overlaps with an ADCP Signature benchmark.
Underice MAVS	353	248	0.05	1e-8 to 1e-6	Weak stratification	Under-ice boundary layer, MAVS suspended 5m depth
Tidal MAVS	20	1.45	0.9 to 1.1	1e-3	Weak stratification	Strong tidal flows
