The current profilers of the French Oceanographic Fleet

The following ADCP is installed on the ships:

  • Supplier: Teledyne RD Instruments
  • Model: ADCP Ocean Surveyor, 38, 75 or 150 kHz.

Three frequencies are available for this sensor: 38, 75 and 150 kHz. Performance in terms of range and vertical resolution depends on the sensor’s frequency. Performance is shown in the table below. Range also depends on the conditions of acquisition (ship noise, quantity of particles suspended in the water, etc.)
