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.

Bureau of Ocean Energy Management (BOEM)
… A workshop on the “Status and Applications of Acoustic Mitigation and Monitoring Systems for Marine Mammals” was held November 17-19, 2009, sponsored by the Bureau of Energy Management, … and better understand the current status of acoustic hardware and software tools for marine mammal monitoring and mitigation as applied to offshore industries. This will include the … PAM and active acoustics may provide an improved understanding of apparent changes in the distribution of calling whales responding to industry sounds, a problem that has plagued at least …
- Journal Article:
Southall et al.
… repeatable analytical framework for assessing relative risk of anthropogenic disturbances on marine vertebrates, with the emphasis on the sound generating aspects of the activity. The … human activities (particularly those that produce sound) influence the likelihood of marine mammal behavioral responses and potential injury, rely principally on generalized … allowing a relativistic means of assessing potential disturbance scenarios, tunable to animal distribution, region, context, and degrees of spatial-temporal-spectral resolution. … 2023-02-27 …
- Report:
Polagye et al.
… 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 …
- Journal Article:
Dahl et al.
… part by basic questions concerning the relation between anthropogenic noise and the ecology of marine mammals. For example, there is concern about the degree to which marine mammals are possibly habituating to, or otherwise being affected by increasing … allude to the noise field’s variation in time, space and angle of arrival (angular intensity distribution). The major anthropogenic and natural constituents of the spectrum are itemized, and …
- Book Chapter:
Donovan et al.
… typically produces large amounts of far-reaching noise, potentially disturbing many marine mammals. The potential to affect the favorable conservation status of many species means …

… by a stressor typically involves combining a dose–response function with information about the distribution of animals and of the stressor. Regulators often prefer a single threshold to a full … calculate the number of animals impacted must draw from the dose–response function, the actual distribution of the animals, and a model mapping how the stressor intensity declines with … of the area and numbers of animals affected. This paper focuses on behavioural responses of marine mammals to anthropogenic sound and demonstrates that a common approach of selecting the …
- Journal Article:
Brown and Simmonds
… There is currently an unprecedented expansion of marine renewable-energy developments, particularly in UK waters. Marine renewable-energy plants are also being developed in many other countries across Europe and … information, including inferences drawn from the impact of other human activities in the marine environment, indicates a significant risk of negative consequences, with the noise from …
- Report:
Sotta et al.
… Brittany, specifically the département of Finistère. The purpose of MERiFIC, which stands for “marine energy in far peripheral and island communities”, is to study the development of marine renewable energies (MREs). Through various issues governing their development: Energy … establishing a shared work programme that includes methods of assessment for the presence and distribution of marine mammals. … 2014-02-01 …

Henkel and Haxel
… for existing nearshore sound levels. Ambient noise is an important habitat component for marine mammals and fish that use sound for essential functions such as communication, navigation, … during their construction and operation present concerns for long-term consequences in marine habitats. Oregon’s dynamic nearshore environment presents significant challenges for … in the beginning of the project due to vessel time constraints) providing a spatial distribution of sound levels, comparisons of noise levels in varying levels of vessel traffic …

Bassett et al.
… route, and a transit area for many cetacean species. A key finding is that the statistical distribution of total sound pressure levels are dependent on tidal currents at the site. … to ambient noise levels at the site, with secondary contributions from rain, wind, and marine mammal vocalizations. Post-processed data from an AIS (Automatic Identification System) receiver …

European Marine Energy Centre (EMEC) and Fox
… project aims to address long term environmental concerns around the development of the marine renewable industry’s emerging technology, through targeted environmental monitoring … and engagement. The potential environmental impacts that can be associated with the marine energy sector are generally site specific making it difficult to draw conclusions about a … around the deployment locations. Marine acoustic sensors will be used to assess fish distribution and abundance near the devices and gain an understanding of fish attraction to …
