Long-term sound and movement recording tags to study natural behavior and reaction to ship noise of seals. [PDF]
Ecol Evol, 2019 The impact of anthropogenic noise on marine fauna is of increasing conservation concern with vessel noise being one of the major contributors. Animals that rely on shallow coastal habitats may be especially vulnerable to this form of pollution.

Ship noise management and the ORCA class of ships.
Marine Pollution Bulletin, 2021 To support Transport Canada's projects to reduce underwater noise from shipping, Defence Research and Development Canada performed a series of experiments based on the Royal Canadian Navy's ORCA-Class training vessels. Sea trials measured onboard vibrations and underwater noise to support the development of a real-time prediction of propeller ...

Environmental Impact of Ships, 2020 Anthropogenic underwater noise has severely increased over the last century and a significant component of noise in marine environments is due to ship traffic. Every year at sea, we observe the continuous movement of more than 60,000 medium to very large commercial vessels, such as cargo ships, bulk carriers, container vessels, tankers, cruise ships ...

Error-Index-Based Algorithm for Low-Velocity Impact Localization
Shock and Vibration, 2022 Flat plates and cylindrical shells are commonly used in large equipment. To locate the low-velocity impact points in these structures, this study proposes an error-index-based algorithm for impact localization.
