600khz ADCP used by Énergie de la Lune in Bordeaux, France

The Rowe Technologies 1200 KHz Acoustic Doppler Current Profiler (ADCP) is a sophisticated device that provides precise profiling and bottom track information at shorter ranges. Unfortunately, the extreme opacity of the water in the Garonne River in Bordeaux perpetuated by high turbidity and high backscatter due to suspended sediment, requires a lower frequency device even in a shallow water column.

Cyril Giry, Scientific Director of Marine Renewables for Énergie de la Lune in Bordeaux France is using a Rowe 600 kHz direct reading Acoustic Doppler Current Profiler (ADCP) on a moored and stationary platform situated on the Garonne. The Garonne is fast moving and rich in sediment and particulate matter giving it a chocolate color, and these conditions maintain an extremely high back scatter environment.
