Instrument:
Shipboard acoustic doppler current profiler (ADCP) (MR08-02 - )
Instrument:
Shipboard acoustic doppler current profiler (ADCP) ( - MR08-E01)
Acoustic Doppler Current Profiler (ADCP) transmits acoustic pulses from a transducer assembly. The transducers receive backscattered sounds from small particles floating with water currents. Using the Doppler shift principle, the backscattered sound data can be converted into components of water current velocity at multiple depths. The shipboard ADCP mounted on R/V MIRAI can measure the speed and direction of water currents for up to 128 layers.

  • ADCP Dataset
  • Absolute currents in ASCII at 5min and each depth in *.vec files in text data page


  • ASCII conversion
  • CODAS(Common Oceanographic Data Access System) that was developed by Prof.
    Eric Firing of University of Hawaii is applied for ASCII conversion. The basic highlights of processing a shipboard ADCP dataset is described below.

    loadping: Create ADCP database.
    refabs: To get ocean reference layer velocity, subtract ship velocity from measured layer velocity.
    smoothr: Smooth the ocean reference layer velocity and get smoothed positions.
    putnav: Apply the new smoothed position to database.
    adcpsect: To get absolute velocity, subtract new ship velocity derived using smoothed positions from measured layer velocity.

    The value of '1E38' is missing value.
    Please see 'ReadMe' for the configuration of 'layer depth', 'layer thickness' and 'layer number', because they have specific values with each cruise.
    The 'x-component' shows the zonal component of the current(+:East, -:West), and the 'y-component' shows the meridional component of the current(+:North, -:South).
