The Mooring Array

The ASCA mooring array, currently deployed, consists of:

  • Two shelf moorings deployed at 80 and 120 m respectively.  These are represented by positions C2 and C3 on Figure 1.
  • Seven tall moorings deployed from 300 to 4500 m, shown as Mooring A to G on Figure 1.
  • Five Current- and Pressure Inverted Echo-Sounders (CPIES) to augment the tall mooring data and deployed from 1200 m to 4500 m and extending the array 300 km offshore.
  • Instruments deployed on the array include 300 kHz and 75 KHz Acoustic Doppler Current Profilers (ADCP) from Teledyne RD Instruments, Aanderaa and Nortek single point Current Meters, Sea-Bird electronics Microcat Sensors and the CPIES themselves.  More information on each of these instruments, along with the acoustic releases and location beacons can be found in our Instruments section.
