*) Exact battery consumption and velocity uncertainty are complex functions of the deployment configuration and temperature.
**)The Aquadopp"! profiler measures the current profile in a user specified number of cells from the instrument out to a maximum range that depends on the acoustic scattering conditions. The lower range should be expected with clear water and small cells and the higher range with large cells and acoustically turbid water. |
