Ocean Sound

CSA Ocean Sciences Inc. (CSA) delivers fully integrated ocean sound and metocean monitoring solutions to support the design, operation, and environmental compliance of offshore projects worldwide. With decades of experience in deep-sea and high-energy marine environments, our systems provide real-time environmental intelligence that enhances operational safety, supports engineering design, and guarantees regulatory compliance.

Ocean Sound Services

CSA offers advanced underwater acoustic services critical to responsible exploration and environmental stewardship. Our solutions support environmental impact assessments (EIAs), permitting, and real-time mitigation for energy, infrastructure, and deepwater mining industries.

Monitoring and Mitigation

  • 24/7 support by expert mitigation acousticians
  • Real-time and post-processed sound level measurements
  • Remote and towed Passive Acoustic Monitoring (PAM) systems

Acoustic Analysis and Modeling

  • Custom sound propagation modeling for site-specific conditions
  • High-resolution footprint mapping and effects analysis
  • Project-produced sound evaluations for marine fauna

Advanced Technologies

  • Proprietary iPAM system for auto-alerts on vocalizations and exceedances
  • Turnkey analytics for large datasets from fixed or mobile arrays

Metocean Services

In support of CSA’s Ocean Sound solutions our metocean capabilities are designed and engineered for long-term offshore deployments, offering robust performance in high-current and corrosive environments. Our services encompass:

Subsurface Monitoring

  • Acoustic Doppler current/wave profilers for wave height, current, and turbulence
  • Conductivity-temperature-depth (CTD) sensors for water column profiling (temperature, salinity, dissolved oxygen, turbidity, fluorometry, pH)
  • Directional wave buoys and bottom recorders for wave analysis
  • Hydroacoustic systems for environmental assessments

Atmospheric Monitoring

  • Wind speed/direction, air temperature, humidity
  • Cloud height, visibility, and precipitation detection

We provide end-to-end support—from design and fabrication to deployment, maintenance, QA/QC, and regulatory-grade reporting—seamlessly integrating data into dynamic positioning  systems, asset integrity models, and command centers.

Our technologies meet compliance standards for Bureau of Ocean Energy Management (BOEM), National Oceanic and Atmospheric Administration (NOAA), and international regulators, providing clients with actionable insights and regulatory confidence.
