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.

This report presents an estimate of the risk of collision between harbour seals (Phoca vitulina) and tidal turbines on the basis of observed behaviour patterns derived from targeted telemetry tracking studies and recent population survey data. The collision risk associated with a proposed turbine array development in the Pentland Firth was used as a worked example of the method.…

Blue whales (Balaenoptera musculus) are distributed worldwide, and although severely depleted by commercial whaling, their abundance off the California coast now appears to be increasing. Little is known about natural causes of mortality of blue whales, but human-related mortality continues despite legal protection. Ship strikes are a significant mortality factor for other species of…

Whale entanglement in fishing gear is a global problem, and underwater ropes associated with this gear are often the cause of injuries that can lead to fatalities. Minke whales (Balaenoptera acutorostrata) are especially at risk because they are relatively small, widely distributed, and often occur in coastal habitats where many types of fishing gear are deployed. It is unknown…

Microphone arrays are an essential tool in the field of bioacoustics as they provide a nonintrusive way to study animal vocalizations and monitor their movement and behavior. Microphone arrays can be used for passive localization and tracking of sound sources while analyzing beamforming or spatial filtering of the emitted sound. Studying free roaming animals usually requires setting up…

Daily POD data and aerial … POD-data even detected a positive trend from 2010 to 2013. On a regional scale, porpoise distribution patterns, as found by aerial survey data, differed between years. These regional … a radius of 20 km around piling. However, there was no evidence for an overall change in distribution patterns at a larger scale within the German Bight over the 5-year study period. …

The objective of this study was to characterize the risk of vessel strikes on large whales and sea turtles from different vessel types that operate in support of the current leased and unleased OCS wind energy areas (“wind farms”) in the Atlantic and to develop a model that accounts for geospatial, temporal, and species-specific parameters in the vessel operations area for these wind energy…

This report describes a study of the abundance of harbour porpoises (Phocoena phocoena) in the waters north of the island Sprogø in the central Great Belt. The study was conducted in the years 2008-2010, before, during and after construction of a small offshore wind farm. The Great Belt is together with the Little Belt and the northern Sound home to some of the highest densities of…
