A fundamentally different approach — no over-the-side deployments, no stopping the vessel.
The system transmits acoustic pulses from a compact linear array mounted to the vessel hull while underway, and analyzes echoes from natural water-column reflectors — no artificial targets or repeated instrument deployment required.
Proprietary signal processing algorithms extract the ocean sound speed profile (SSP) from the received echo data — covering approximately 0–30 m depth with a 1 m array and up to 0–90 m with a 3 m array, in the upper water column where sound speed variation is most significant for sonar applications.
Ocean sound speed profile (SSP) data is obtained continuously along the vessel track — not just at individual cast locations — supporting better sonar accuracy and survey efficiency.
AtlanticEcho SSP gives operators an accessible, workflow-compatible way to get more frequent, less disruptive sound speed data — without the cost and complexity of legacy systems.
