Performance of three hydrophone flow shields in a tidal channel

Pseudosound caused by turbulent pressure fluctuations in fluid flow past a hydrophone, referred to as flow noise, can mask propagating sounds of interest

Marine energy converters: Potential acoustic effects on fishes and aquatic invertebrates

The placement and operation of marine energy deployments in the ocean have the potential to change flow patterns, decrease wave heights, and/or remove energy from the oceanographic system.

A Remote Sensor for Marine Mammal Localization

The deployment of infrastructure in the ocean is often slowed due to the potential harm of animals in the area. In the Bay of Fundy, the deployment of tidal farms have been explored for several years, however there is a large population of harbour porpoises.

Imaging Sonar Data Automation Feasibility Study

Multibeam imaging sonars can be used to monitor fish and marine mammal presence and behaviours in the near-field of tidal turbine installations, including evaluating avoidance, evasion, and potential blade strikes

A Review of Modeling Approaches for Understanding and Monitoring the Environmental Effects of Marine Renewable Energy

Understanding the environmental effects of marine energy (ME) devices is fundamental for their sustainable development and efficient regulation. However, measuring effects is difficult given the limited number of operational devices currently deployed.
