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 | 0.45 | 0.15-0.2 | 1e-8 to 1e-5 | Unstratified, but shear-induced anisotropy | Viscous subrange is occasionally resolve. 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 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 |
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 |
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) |
