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.
Dive into the technology, the evidence behind it, and how we are looking to collaborate.
Why sound speed profiling matters for sonar, offshore energy, navigation, and underwater communication.
