EC150-3C Acoustic Doppler Current Profiler (ADCP) & echo sounder

Combining a scientific echo sounder with acoustic doppler current profiler (ADCP)

The Simrad EK80 once again confirms its position as the leading scientific instrument for measurements of aquatic ecosystems. With the EC150-3C transducer, the EK80 repeats its performance as an innovative acoustic system. It combines the absolute backscatter measurements from the split-beam echo sounder with physical oceanographic measurements from the acoustic doppler current profiler (ADCP) beams. And it all happens in one single instrument.

Simrad EC150-3C transducer

Key features

  • Combined ADCP and echo sounder in the same unit
  • Transducer and transceiver in the same housing. Only power, Ethernet, and synchronization (optional) to connect
  • State of the art current velocity and backscatter measurements
  • Controlled by the EK80 software
  • Easy synchronization of ADCP and scientific echo sounder
  • Wideband capability: 150 ± 12kHz
  • Built-in sphere calibration of echo sounder
  • Auxilary sensor data are integrated into the data files, such as heave, pitch, roll, GPS information, sound speed, and temperature values
  • User-friendly and flexible user interface
  • Low installation costs by reducing the system complexity

Typical application

  • Ocean observatories
  • Water column profiling
  • Fixed installations onboard vessels

In addition to the backscatter measurements, the EK80 offers accurate current velocity measurements. The speed and direction of the currents throughout the water column are measured and presented as a function of the depth. This offers a valuable tool for understanding how organisms, nutrients, and other biological and chemical constituents are transported through the ocean. The information can also help understand how climate changes affect how warm water is transported through the oceans. Physical current measurements can also improve models for how the sea currents behave. This improves various forms of the ocean and meteorological forecasts.

The acoustic doppler current profiler (ADCP) and narrow split-beam functionality offered by the Simrad EK80 are based on the EC150-3C transducer. The EC150-3C is a phased array transducer with advanced transceiver circuitry inside. The common EK80 user interface is used for operational control. You can use the EK80 and the EC150-3C transducer as a “stand-alone” system. You can also add the EC150-3C to an existing EK80 system by simply connecting the additional unit to your Ethernet switch.

To use the EC150-3C you need EK80 software version 2.0.0 or later. The EC150-3C is provided with a dedicated power supply to feed the built-in electronic circuitry. The transducer is easily installed using mounting- and clamping rings. The open-ended cable between the transducer and the power supply is provided with the delivery.

This screen capture presents four typical views from a Simrad EK80 using the EC150-3C transducer and ADCP functionality. The top three views present the current water velocity in the north/south, east/west, and vertical (down/up) directions. The colours indicate the water speed as specified by the colour scale. The bottom view contains the traditional echogram provided by one of the four ADCP beams. In this view, the colours indicate the backscatter intensity.
