Passive Acoustic Monitoring (PAM)
ThayerMahan
Ship strikes and construction noise threaten endangered marine species like the North Atlantic Right Whale. Regulators require mitigation, and communities expect stewardship. Our PAM service allows you to obtain both – while reducing the number of unnecessary shutdowns or slowdowns you have to endure. Our advanced sonar systems listen to sounds in the ocean and detect whale vocalizations. We classify and monitor marine mammals, so appropriate actions can be taken to protect them.
Undersea Surveillance
ThayerMahan
Unmanned systems enhance strategic military capabilities by freeing high-end assets for contested and more challenging missions and enabling persistent surveillance in many important but uncovered areas through distributed sensing. Proven, scalable unmanned capabilities offer measurable improvements within 1–2 years, supported by a hybrid architecture that boosts cost-effectiveness and operational flexibility. ThayerMahan systems align with the Navy’s strategic vision for a hybrid fleet and affordable mass deployment, presenting immediate opportunities for impactful deployment faster than alternative solutions.
UXO / MEC Classification & Removal
ThayerMahan
Our team is comprised of expeditionary maritime operators with U.S. EOD backgrounds of field experience. They understand that MEC is not a one-size fits-all challenge – it demands operational insight and situational awareness to identify the safest, most efficient course of action.
We provide supervised dredging/uncovering, visual and sonar confirmation, and rigorous classification to separate UXO/MEC from benign debris. We also reduce relocation time and ensure safe, accurate, and efficient operations.
