Atlantic Echo is developing a remote underway sound speed profiling system — giving marine survey and sonar operators continuous SSP data without disrupting vessel operations.
High-precision sonar depends on accurate sound speed profiles — but collecting them typically means stopping the vessel or accepting significant trade-offs.
Require the vessel to stop for each cast. Provide a profile only at that time and location — not continuously along the track.
Underway capable but require significant capital investment, deck space, and ongoing maintenance. High operational burden limits adoption.
Single-use instruments with recurring per-cast consumable costs, limited depth, and limited resolution. Not reusable.
These limitations become even more significant in challenging environments such as high sea states and icebreaking conditions — exactly where accurate SSP matters most.
