The Importance of Empirical Particle Motion Measurements for Monitoring Underwater Noise from Wave Energy Converters
Underwater noise from Marine Energy Converters (MECs), including Wave Energy Converters (WECs), is a recognized stressor for marine organisms. Current monitoring guidelines focus on scalar pressure, but particle motion is equally important, especially in complex shallow-water environments where WEC…

Controlling tip vortices and cavitation with a grooved-tip design for tidal turbines
Cavitation can result in blade erosion, vibration, and cavitation noise due to bubble collapse. Tidal turbines' blade tips experience the highest flow speed, and thus, risks of cavitation increase due to low pressure inside tip vortices at high Tip Speed Ratios (TSRs). This can cap their power…
