Benchmark datasets for velocity measurements

These datasets are temporarily in a dropbox 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	[math]\displaystyle{ \varepsilon }[/math] range	Stratification/shear information	Comment
Units	[m]	[m]	[m/s]	[W/kg]
Tidal slough	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 low quality	185	0.4	<0.3 but usually 0.1	1e-7 to 1e-4	Bottom one in log-layer using the classical definition	Low-quality & noisy dataset
Tidal shelf high quality	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
Intertidal small waves	ask JM	0.4	<0.18	1e-6	coastal area with weak stratification	std(U)/mean(U) is roughly 1 (JM)
