ADCP BD

ADCP : Acoustic Doppler Current Profiler

A Doppler-based current meter for profiling water column and flow.

How it works :

  • Emits acoustic signals that bounce off suspended particles.
  • Echoes are analyzed to measure particle and current velocity.
  • Generates vertical profiles of current speed and direction.

Applications :

  • Ocean current monitoring
  • River discharge analysis
  • Flow field mapping
Sondes XBT4

Oceanographic probes

Designed to profile the full water column with high accuracy.

Capabilities :

  • Measures temperature, conductivity, and pressure.
  • Sends a complete water column profile during descent.

Implementation options :

Available with a range of launchers and acquisition units.
