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

Towards Estimating Probability of Fish-Turbine Encounter: Using Drifters Equipped with Acoustic Tags to Verify the Efficacy of an Array of Acoustic Receivers
Understanding the abundance and distribution of fish in tidal energy streams is important for assessing the risks presented by the introduction of tidal energy devices into the habitat
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.

Echofilter: A Deep Learning Segmentation Model Improves the Automation, Standarization, and Timeliness for Post-Processing Echosounder Data in Tidal Energy Streams
Understanding the abundance and distribution of fish in tidal energy streams is important for assessing the risks presented by the introduction of tidal energy devices into the habitat
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.
The Ups and Downs of Using Active Acoustic Technologies to Study Fish at Tidal Energy Sites
Active acoustic instruments (echosounders) are well-suited for collecting high-resolution information on fish abundance and distribution in the areas targeted for tidal energy development, which is necessary for understanding the potential risks tidal energy devices pose to fish
Estimating the probability of fish encountering a marine hydrokinetic device
Strong tidal currents in eastern Maine, USA, make that region attractive for tidal power development.

Soundscape characterization in a dynamic acoustic environment: Grand Passage, Nova Scotia, a planned in-stream tidal energy site
The marine environment in the Bay of Fundy hosts a dynamic and diverse soundscape that is a fundamental component of the local ecosystem.
