How Noisy is Too Noisy?
The United Kingdom’s energy strategy for the future is heavily reliant on off-shore wind turbines. The unknown element here is how the underwater noise of these turbines, during construction, and in usage, will effect the environment. The University of Newcastle’s Sustainability blog posted about the preliminary challenges of these turbines.
The masts which hold the turbines must initially be hammered into the sea floor, destroying habitat space, and causing loud echos and rippling waves from it’s center. In coalition with other University research teams, Newcastle’s research team spent four days on the water collecting samples of species and water with various technologies in order to map the ecosystem before construction, during, and usage periods. This will help them understand the effects of underwater noise in their marine ecosystems, and design ways of limiting potential issues into the future. Read their blog post for more information on this endeavor, and other sustainability news.
In July 2013 the RV Princess Royal was home to a group of UK underwater sound specialists, called the Bio-Acoustic Research Consortium (BARC). This new project is led by Dr Per Berggren from Newcastle University’sSchool of Marine Science and Technology and it brings together a range of noise specialists, ecologists and industry professionals with a common aim: to better understand the impact of underwater noise on marine ecosystems.
The consortium has attracted grant funding from the Natural Environment Research Council’sMarine Renewables Knowledge Exchange Programme to explore the environmental challenges associated with offshore wind development, an industry that continues to grow rapidly. The Newcastle Institute for Research on Sustainability (NIReS), also supplied a small grant towards equipment costs which has funded the purchase of six hydrophones, called C-Pods, for detecting marine mammals. It is hoped the knowledge gained from the project can be fed directly back to industry…
