Note
titleAttention:

The Doppler Log (DO - Log) is part of nautical equipment. The operation belongs to the bridge only.

Summary

Sensorweb integration
urnvessel:heincke:do-log
contenttypeSummary

The Doppler log measures speed through water by using the Doppler effect of sound signal reflected from the seafloor or from suspended matter in the water column. Wärtsilä SAM 4682 transducer consists of a total of 3 hydro-acoustic elements of 270 kHz.
