Ecology Using arrays that can include dozens of microphones , for instance , researchers have been able to closely track tiny birds through nearly impenetrable tropical undergrowth and map out their territories
May 05 2011 The latest on far-offshore floating wind turbines News Ocean Wind turbines Add comments Regular readers will know that I’m excited by the potentials for far-offshore floating wind turbines . Less construction noise , less disturbance of the seafloor , more construction can take place on land rather than at sea meaning less loud boat activity it all adds up to much less noise impact in our coastal ocean environment , which is very sensitive to new noise . Not only that , but the winds are stronger farther . out Renewable Energy World has a great current overview of where the R D is at today for floating turbines , with summaries of each of the leading designs being tested , and assessment of the likely timeframe the cautious among them still say we’re a decade away some are more
Apr 27 2011 NREL to study turbulence in wind turbine wakes Science Wind turbines Add comments The US National Renewable Energy Laboratory is about to begin a new study of the turbulent wakes that appear downwind from wind turbines . Such turbulence can decrease the efficiency of turbines as well as creating physical stresses on the machinery many researchers also suspect that inconsistent wind speeds across the rotor diameter contributes to increased noise . It’s certainly easy to imagine that turbines inside the wakes pictured at the left from an offshore wind farm in Denmark , where moisture reveals the normally invisible patterns might be under stresses that would increase noise . output For more on the NREL study , see this feature in Science Daily Leave a Reply Name Email not required

The Greater Yellowstone ecosystem of 28 million acres, is home to one of the largest collections of wildlife in the U.S. Rapid residential and energy development are threatening the future of the region’s iconic wildlife. In observance of Endangered Species Day, May 20th, we share this film which highlights the efforts of those working together [...]
Aboard Mission Blue, scientist Greg Stone tells the story of how he helped the Republic of Kiribati create an enormous protected area in the middle of the Pacific – protecting fish, sealife and the island nation itself.
