Normandeau provides radio telemetry services for the remote observation of animal behavior. Radio Telemetry transmits wireless signals carrying information from externally or internally radio-tagged animals to study migration, behavior, survival, and habitat use in a variety of aquatic and terrestrial environments. Our scientists provide the expertise to design and conduct radio telemetry studies appropriate for the specific needs of our client projects. We also provide radio telemetry services for applications such as natural resource management; hydroelectric, nuclear and fossil fuel energy operations; offshore and onshore wind and other renewable energy development; and marine and coastal development efforts.

Normandeau uses state-of-the-art radio telemetry technologies to provide clients with high-quality results for applications such as:

Fixed-location Radio Telemetry for Migration, Passage & Survival Studies: Normandeau scientists have deployed multiple stationary antenna receivers along rivers to detect and track the movements of juvenile and adult fish of many species over long time periods. Cost-effective information of high certainty can be provided to evaluate survival through hydroelectric turbines, effectiveness of bypass routes and guidance technologies, migration patterns, and anthropogenic impacts to migration. In addition to the vast experience of radio telemetry services offered in aquatic environments, study of radio-tagged terrestrial wildlife like white-tailed deer and black bears can provide information on survival and movement for evaluating potential impacts for a variety of project.

Mobile Radio Telemetry: Fixed-location antennas and mobile tracking have been used to study the home range, activity patterns, and environmental conditions associated with an animal's movement. Coupled with sensory tag information or ancillary environmental measurements radio telemetry can provide important information in evaluating habitat use for resource or impact assessments.

Normandeau also provides specialized expertise required to process and analyze large sets of data such as those collected during radio telemetry studies. Data processing services include signal data processing, database management, statistical analysis, and data visualization using leading industry software such as SAS, Matlab, Echoview, Primer-E, R, and ESRI GIS.

As a science-based environmental consulting firm with over 40 years of experience providing environmental consulting services for aquatic species impacts, Normandeau stands out for its ability to guide you to sound, defensible and reasonable science-based decisions for project and regulatory compliance.
