FOR IMMEDIATE RELEASE July 9, 2025
San Diego, CA – Biospherical Instruments, Inc., a leader in aquatic optical sensing, today
announced its expansion into passive acoustic monitoring (PAM) through a strategic
partnership with RTsys SAS, a specialist in underwater acoustics based in France. This
development marks a major step forward in Biospherical’s evolution from highperformance radiometry to a fully integrated optical-acoustic sensing provider.
Integrated Optical-Acoustic Solutions for Modern Environmental and Defense
Challenges By embedding RTsys acoustic recording capabilities into Biospherical’s
modular platforms—buoys, moorings, and autonomous systems—customers now benefit
from seamless, co-located data streams that capture both light and sound in aquatic
environments. This dual-modality approach strengthens marine ecosystem monitoring,
supports compliance in offshore construction, and enhances environmental intelligence
for naval operations.
“Our customers have long relied on our optical sensors to characterize aquatic
environments with precision,” said Vieri Tenuta, President of Biospherical Instruments.
“Now, by integrating proven acoustic systems from RTsys into our offerings, we’re delivering
the next generation of multi-sensor systems—where radiometric and acoustic data
converge to provide actionable insight across both commercial and defense applications.”
Why RTsys Enhances the Biospherical Platform The addition of RTsys acoustic
technology allows Biospherical to deliver:
- Unified Sensor Packages: Fully integrated radiometric and acoustic sensing
systems deployable on existing Biospherical platforms. - Extended Monitoring Capabilities: From detecting biological activity to tracking
construction noise or vessel traffic, customers gain new ways to quantify
underwater conditions. - Mission-Critical Versatility: Enhanced support for naval ISR, environmental
compliance, and autonomous platform integration.
