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.

… 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 …

Offshore wind farming is a new emerging technology in the field of renewable energies. This study investigates the potential impact of the construction of one of the first major, offshore wind farms (>100 MW) on harbour porpoises Phocoena phocoena by means of acoustic porpoise detectors (T-PODs) monitoring porpoise echolocation activity. The monitoring program was established as a…
