Falmouth Scientific’s AquaPulseTM Surpasses 10 Million Shots Without Maintenance or Performance Degradation
Falmouth Scientific announces that its AquaPulseTM Acoustic System has exceeded 10 million shots in a recent survey without maintenance, failure, or any change in acoustic output. This highlights superior reliability and consistency for marine geophysical surveys.
AquaPulse delivers high-resolution, bubbleless acoustic pulses for sediment profiling. The high energy low frequency source output was able to produce acoustic images to depths of 1000m below the seabed in 10m water depth. The AquaPulse stands out among other acoustic sources in the survey space that also utilizes traditional seismic sources, such as sparkers, boomers, and air guns. These devices require tip replacement, source plate energy degradation and mechanical parts replacement, and rebuilds. The AquaPulse does not require any of these maintenance tasks to maintain a repeatable acoustic output signature. No specialized power source is required for vessel integration. The AquaPulse operates on a standard 120V/220V outlet with minimal energy consumption (1-2 kW). Pre- and post-project testing confirmed no change in the system’s acoustic signature after 10M shots, proving outstanding, consistent, repeatable performance.

Tracking the sun with floating solar
Floating solar presents many benefits, offering a source of renewable energy where land is scarce. Instead of covering valuable land, this technology uses large bodies of water, usually lakes and reservoirs, to host arrays of solar panels. Floating solar studies have also shown multiple water quality and water retention benefits, with a reduction in evaporation and harmful algae blooms.
As a leader in floating solar, California-based Noria Energy develops resilient, renewable energy systems that generate long term value. Notable achievements include the development of the largest floating solar photovoltaic system in the US (in Healdsburg, California) when built in 2022 and the largest floating system on a hydroelectric reservoir in the western hemisphere, located in Urra, Colombia.
Dynautics started working with Noria in summer 2023, to help develop an initial prototype of Noria’s new product, AquaPhi. AquaPhi is a patented, autonomous positioning system that enables rotational tracking of the sun. It converts static floating solar into a movable platform by using thrusters on the underside of the array. Current floating solar projects have anchors that restrict the arrays to a fixed orientation, limiting energy production.
Collaborating closely with Noria and working to a tight timeline, Dynautics customised its existing autopilot and control solution for the AquaPhi prototype on a 10m-by-10m floating array with eight thrusters. The control system regulates the power supplied to each motor and direction of thrust to counteract wind and water currents. Thanks to some custom coding, developed by the Dynautics team, the solar array can also be programmed to stay in one location and rotate about its vertical access to track the sun, producing up to 20% more energy throughout the year and optimising site operations with easy repositioning of the array on the water.
Jimmy Raiford, Head of Technology Development at Noria Energy said:
“Dynautics had the expertise and willingness to provide a customised solution for our floating solar tracker. Their team was very responsive and easy to work with, helping us meet tight deadlines and troubleshoot issues for this novel application of their control technology. The result is a product that will provide more energy and value to our customers.”
Noria Energy plans to continue product development of AquaPhi for deployment on commercial projects and is keen to continue the partnership with Dynautics. The Dynautics autopilot solution, with its optimised control logic, will enable Noria to accommodate more thrusters going forward for larger islands.
