Services | HYDROACOUSTICS
InstrumentationNormandeau’s hydroacoustic services use underwater sound as a remote sensing tool to study living aquatic resources and physical attributes of ponds, lakes, rivers, estuaries and oceans. Hydroacoustics can provide many cost-effective solutions that offer higher spatial and temporal resolution, less sampling effort, fewer sampling impacts to habitat and biota, and potentially fewer sampling biases than many traditional sampling methods. Normandeau scientists can provide the expertise to design and conduct a hydroacoustic sampling plan appropriate for each client’s needs. Normandeau can also provide consulting services using hydroacoustics for:
A selection of our inventory available for hydroacoustic services includes:
Hydroacoustic technologies used by Normandeau, and their potential applications, include the following:
Fisheries Acoustics: Fixed-location and mobile surveys using sonar (sound and navigation ranging) to quantify or describe abundance, movement, distribution, and behavior of fish and plankton.
Acoustic Hydrology: Fixed-location and mobile surveys using acoustic Doppler technology (ADCP) to quantify magnitude, volume, and direction of the movement and distribution of water, as well as turbulence and wave action. ADCPs can also be used to continuously monitor suspended sediments in the water column (e.g., plumes from dredging)
Bathymetry: Mobile surveys using echosounders to measure depth of water bodies based on two-way travel time of echoes and sound speed.
Habitat Mapping: Mobile surveys using single-beam, multi-beam, or side scan sonar to characterize the seafloor or bottom substrate based on sonar imagery or acoustic backscatter properties.
Data Processing: In addition to field collection services, Normandeau offers expertise in many industry standard software packages to process and analyze a variety of hydroacoustic data.
