Information is currently being transferred onto the wiki about the additional datasets.
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 | 0.15-0.2m/s (median) | 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 | <0.3m/s but usually 0.1m/s | Bottom one in log-layer using the classical definition | Low-quality dataset | |
Tidal shelf high quality | 250 | 1.4? | <0.8?? | 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 | 1e-3 | weak stratification | Strong tidal flows |
