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 0.15 and 0.45 0.15-0.2 1e-8 to 1e-5 Unstratified, but shear-induced anisotropy Unusual spikes at 0.15 m. At 0.45m, the viscous subrange is occasionally resolved
Tidal shelf low quality 185 0.4 and 1.4 <0.3 but usually 0.1 Bottom one in log-layer using the classical definition Low-quality dataset
Tidal shelf high quality 250 1.4? <0.65 Stratified bottom log-layer High-quality dataset with phase wrapping
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)
Underice MAVS 353 248 0.15 max. 1e-8 to 1e-6 weak stratification *under ice boundary layer, MAVS suspended 5m depth
Tidal MAVS 20 1.45 1 1e-3 weak stratification Strong tidal flows
