Ocean Sound & Marine Mammals

on . Posted in Business Lines

CSA’s Ocean Sound group within the Ocean Sound & Marine Mammals business line focuses on providing acoustic solutions for the marine environment in the client’s area of interest by investigating sources of sound and their potential impacts. Regardless of sound source type, biological or anthropogenic, CSA’s Ocean Sound team can detect, classify, locate (DCL); model, monitor; and measure these sources.

Ocean Sound Services

  • Professional and highly skilled acousticians with 24/7 mitigation consultancy
  • Acoustic modeling
  • Acoustic measurements
  • Sound source characterization
  • Sound exposure modeling
  • Assessment of masking and cumulative impacts
  • Acoustic data mining of previously acquired data
  • Remote Passive Acoustic Monitoring (PAM) through our web-based, real-time monitoring system and
  • Towed PAM systems for mitigation compliance with protected species.

CSA’s vision is to continue to develop technically advanced marine sound solutions and provide expert consulting to the offshore industries, allowing our clients the ability to better understand and mitigate their operational risks.

Acoustic Monitoring

CSA provides a unique solution for acoustic monitoring using the SONS-DCL software. SONS-DCL software can accommodate inputs from a variety of sources, for example, towed arrays, fixed buoys, autonomous recorders, gliders, and free floating expendable buoys. Using SONS-DCL, CSA has the capability to collect and archive data, conduct periodic data transfers, or under certain conditions transmit data in real time to a web server. This system can be used in both nearshore and offshore waters for a variety of purposes such as bioacoustic monitoring, population density estimates, sound source characterization, facility security, or other research/industry purposes.

As a CSA client, access to project data is continually available via a password-protected area of the website (www.oceansound.com). Oceansound.com is designed for ease of operation (non-expert) and provides a monitoring and analysis system that operates 24 hrs/day and without the need for post-processing.  This highly functional system is designed to be utilized with acoustic data containing large spatial and temporal scales. CSA offers this innovative technology and believes it will provide our clients the best technical solution for their acoustic monitoring needs.

Marine Mammals

The Marine Mammals team provides fully trained visual, acoustic, and aerial observers for all marine and offshore industry operations. We offer full environmental assessment and mitigation support for government and private entities in offshore marine and coastal communities. Our personnel are available 24/7 for rapid response anywhere in the world.

Oil, Gas, and Renewable Energy
CSA personnel provide BOEM and NOAA-compliant training, assessment surveys, and mitigation services to the seismic, oil and gas, and renewable energy industries and offer a full range of services for protected species programs throughout all project phases, from pre-construction through decommissioning.

Bioacoustic Monitoring
CSA offers enhanced passive acoustic marine mammal detection and localization capabilities for all types of mitigation. Our specially developed acoustic monitoring system (SeaBAM) is effectively used in offshore geophysical/geotechnical surveys, hazard site surveys, migration monitoring, ship traffic studies, and harbor mitigation monitoring.

Dredging and Marine Construction
Dredging and marine construction often require the successful combination of a wide variety of environmental services. CSA provides multi-species assessment, turbidity monitoring (both active and fixed), sensitive habitat protection, and overall environmental management in support of dredging and marine construction projects. All personnel hold appropriate permits and letters of authorization for their assigned duties.

Aerial Surveys
CSA supplies qualified and experienced personnel for offshore and coastal wildlife surveys. Our staff have decades of survey experience for marine mammals, including manatees, right whales, sea turtles, and coastal and pelagic birds.

Project Consultation and Planning
CSA provides cradle-to-grave project management assistance as well as consultation for specific needs or project requirements, including desktop surveys, project planning, permitting assistance, literature reviews, and agency consultations.
