Profile underwater sound at programmed depths to support environmental soundscape and marine-noise monitoring, processing observations onboard and transmitting results by Iridium after resurfacing.
Technical detail
Core features
Programmable profiling and acoustic sampling to a vendor-rated 1,000 metres
Acoustic measurements at selected depths during ascent
Onboard processing of acoustic parameters and spectra
Iridium short-burst transmission after resurfacing
Freely drifting Lagrangian mission architecture
Vendor describes approximately 300 daily profiles for a roughly one-year mission
PABLO
Passive acoustic monitoring
Profiling float
Iridium SBD
Ocean soundscape
Use & integration
Recorded applications
Underwater soundscape monitoring
Anthropogenic marine-noise assessment
Marine-mammal and environmental acoustic observation
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
A 2024 peer-reviewed Santos Basin study reports 234 PABLO launches during 2015–2021, with 226 floats returning data. This is substantive environmental field evidence, while exact current configuration, defence qualification and acceptance remain separate questions.
Commercial availability
MetOcean maintains a public PABLO product page, but current unit pricing, production lead time, supported payload options and standard mission package are not disclosed.
