Information is currently being transferred onto the wiki about the additional datasets.

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
Lake 4.3 0.12 <0.1m/s Unstratified Shallow Lake (DW)
Surface waves large orbital sigma vs mean current (SM)
Surface waves sigma/U is roughly 1 (JM)
