This site-wide search returns results for all documents, events, metadata, and stories in Tethys, prioritizing the best matches. Partial word matches are returned (e.g. "environment" finds "environmental"), but every entered term must be found. If you don't find any results, try reducing the number of words entered or removing special characters. Filters to the right can help narrow your search. Tethys now features an integrated search with other marine renewable energy databases in PRIMRE - click the buttons below "Showing Results for" to search other integrated databases.

… Effects of noise from seismic surveys on marine mammals need to be understood so that they can be appropriately mitigated. This study examined effects of large airgun arrays (79-110 l) on a variety of marine mammal species in the waters of British Columbia and Washington at long distances (1 to > 70 km). … detection, technical constraints limit their usefulness. Scheduling surveys around seasonal distribution of species of concern, limiting periods of exposure, and routing airguns to ensure …

… Understanding the impacts of anthropogenic sound on marine mammals is important for effective mitigation and management. Sound impacts can cause … dive information and is influenced by the underwater soundscape and the historical whale distribution in the region. In the absence of noise disturbance, the simulator is shown to recover the historical whale distribution in the region. When noise disturbance is incorporated, the whale’s behavioral …

… is an increasing need for an understanding of potential noise impacts from this development on marine mammals. Pile-driving of offshore wind turbines produces loud, low frequency sound that … first step is to understand the current baseline ambient noise levels and the spatiotemporal distribution of marine species that could potentially be impacted. In this study, the project … for three years to characterize underwater ambient noise levels and identify vocalizing marine mammal species within and around the Maryland Wind Energy Area (WEA). The project partners …

… uncertainties is the effect that the noise generated by tidal turbines might have on fish and marine mammals. Consequently, it is desirable to better understand these interactions through … noise to evaluate the effectiveness of studies to characterize turbine noise and the marine mammal response to this noise. Because both turbine noise and ambient noise vary in time, the description is probabilistic. The time distribution of turbine noise is derived from measurements of a similar tidal turbine and …
