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, but beaked whales are widely distributed and can be found in virtually all deep-water marine habitats that are free of ice. Some areas of high beaked whale abundance have been identified, but the geographic distribution is poorly known for most species. Beaked whales are both visually and acoustically …

… Underwater noise is a severe annoyance and danger to marine life. The innovative HSD (hydro sound damper) leads to an effective general method to … noise. HSD was developed and patented between 2007 and 2010 by the author to reduce general marine noise and especially offshore piling noise. The theory and the acoustical background of … The resonance frequency of the HSD-elements, the optimum damping rate for impact noise, the distribution and the effective frequency range can be fully controlled. Offshore tests and serial …

… The human presence in the worlds’ oceans is increasing, in response to the growing demand for marine resources. This expansion of human activities will increase pressure on marine ecosystems and demands a responsible ocean management, to ensure the sustainable use of … We found that areas of high impact were strongly influenced by seasonal variations in the distribution of cetaceans. In this case study, we identified an area of high impact in the …

… Phocoena phocoena has become a focal species in relation to management of human activities and marine habitat conservation efforts. In this study, acoustic and visual time series of harbour … as the survey data. Spatial modelling based on selected key predictor variables showed the distribution of harbour porpoises to alternate between 2 upwelling cells depending on the …

… economic, technological and policy drivers is behind a recent upsurge in the use of marine autonomous systems (and accompanying miniaturized sensors) for environmental mapping and … equipped with a single-frequency echosounder to collect information on zooplankton and fish distribution. The other glider carried a Passive Acoustic Monitoring system to detect and record … fish/cetacean detections within the water column. The broader implications of this study for marine ecosystem monitoring with submarine gliders are discussed. … 2014-09-01 …

Rice et al.
Differing physical characteristics and levels of biological, environmental, and anthropogenic sounds contribute in varying levels of noise in different ocean environments. As a result, animals migrating over large ranges or widely distributed species are now exposed to a myriad of different acoustic environments, within which they must navigate, forage and reproduce. Given current increases in…

This suggests that the males' display behaviour may also … males clearly adapt their temporal and spatial behaviour patterns to variations in female distribution and density. These results suggest that male mating strategies in aquatically mating …
