Dr. Mohammad Reza Mousavi and Prof. Len Zedel at the NRC Towing Tank data acquisition setup.
Prototype validation conducted at the National Research Council's towing tank facility — a large controlled test environment enabling repeatable acoustic measurements.
The Launch, Holyrood, N.L.
Initial ocean field testing conducted in Holyrood, Newfoundland — demonstrating the system's operation in real open-water marine conditions.
The Launch, Holyrood, N.L. · August 2026
Atlantic Echo returned to Holyrood for a second round of open-water testing with a next-generation prototype — redesigned for a higher operating frequency and a smaller, more compact size. The team deployed the system from the vessel Silver Dolphin 30 and collected live sound speed profile data over multiple casts.
Further ocean testing is planned to continue validating performance, depth coverage, and operation across a wider range of marine conditions.
We're looking for strategic partners to support pilot testing in operational marine environments.
