• Description:
  The pressure-equipped inverted echo sounder (PIES) is a powerful oceanographic tool that can provide, when combined with historical hydrographic data, full-water-column estimates of temperature, salinity, density, and dynamic height anomaly. Arrays of PIES can provide full-water-column estimates of geostrophic velocity as well. As with any measurement system, the PIES has limitations, but it also has significant strengths, including: relatively low equipment costs; simple deployment/recovery requirements; long deployment lengths (up to 5 years); and the ability to acoustically transmit daily-averaged data to a nearby research ship without recovering the instrument. These strengths make the PIES a good tool for the study of ocean currents in many deep ocean regions.
