    Nov 16 2011 Moderate noise changes bird communities Bioacoustics Effects of Noise on Wildlife Science Wind turbines Add comments Research summary of Francis , C.D . Ortega , C.P . Cruz , A . 2011. Noise pollution filters bird communities based on vocal frequency PLoS ONE 6(11 e27052. An ongoing research project in New Mexico continues to shed more detailed light on the question of how moderate human noise affects nearby wildlife . In a study design that effectively separates out the impact of the noise from other habitat disruption effects , Clint Francis and his colleagues are finding that some species are displaced , while others seem to thrive in areas with coalbed methane compressor stations creating noise around the clock . The most recent paper to be published by Francis et al finds

    Nov 30 2011 Onshore wind farm raises ocean noise concerns in Chile Effects of Noise on Wildlife News Ocean Wind turbines shipping Add comments For the first time , an onshore wind farm has triggered calls for caution from marine mammal protection organizations . The 2500-acre , 56-turbine wind farm will be built along a steep shoreline that funnels nutrient-rich waters from Antarctica to the surface , spawning a dense aggregation of phytoplankton and krill . Along the coast of Isla Grande de Chiloé , blue whales and right whales gather from January to April to feast on this abundance blues come as close as 400m to shore , and rights have been seen only 5m . offshore Environmentalists , including local organizations like Santiago’s Centro de Conservación Cetacea , and international voices

    , Dec 09 2011 New tech may reduce harmful noise of sonar , airguns Effects of Noise on Wildlife Ocean Sonar Add comments Several new R D projects are underway by providers of ocean technology , each of which either aims to reduce the harmful behavioral impacts on marine creatures , or may limit harmful impacts as a byproduct of their . innovations My good friend Michael Stocker already wrote up a solid blog post that summarizes three such projects with links to source material and more information . Head on over to his Ocean Conservation Research blog to hear more about sonar signals modeled on sperm whale clicks likely to be far less distressing for whales and dolphins that today’s grating signals continuous low frequency sonar which could reduce the source level and airguns with less

  • Oregon county approves wind farm within its 2-mile setback

    Dec 05 2011 Oregon county approves wind farm within its 2-mile setback Default Add comments The Umatilla County Commission approved construction of a 33-turbine wind farm , rejecting a citizens’ challenge of the recent OK given by the County Planning Commission . In June , Umatilla County enacted a 2-mile setback provision for new wind farms , but the Chopin Wind Project application was submitted in April , so was not subject to the new rules . The 2-mile limit is at least twice that used in other Oregon . counties The County says the Chopin Wind Project , which will be built using 3MW turbines , will be subject to Oregon’s state noise standard of 36dB another Oregon county recently decided not to enforce this limit the state delegated enforcement to the counties years ago The 36dB limit
