This white paper will give you an in-depth understanding of what makes Pressure Inverted Echo Sounders (PIES) such a key part of the physical oceanographers' toolbox. In it, we will delve into published papers, deployment strategies and further applications for PIES technologies. The white paper also provides examples of recent uses of PIES in physical oceanography. These illustrate this measurement technique provides distinctive long-term data at oceanographic locations relevant to studies of climate change, meteorology and the subsea acoustic environment.
What's "under the hood" and the technology that makes up Pressure Inverted Echo Sounders (PIES).
This isn't a theoretical whitepaper, real-world case studies and published papers on long-term deployment are shared.
Delve into the history of PIES and how the technology has been shaped by theoreticians, observationalists and modellers.
Advances in technology mean our PIES can now self-calibrate and be used with unmanned surface vehicles (USV).
Discover what how our PIES have been used for; from measuring currents to long-term tectonic plate measurements.
The best ways to deploy PIES including a single instrument, pairs, line and 2D arrays, are described with documented findings.
