Water quality alerts do not seem to deter some surfers
August 16, 2014 07:23 AM - Oregon State University
Nearly three in 10 surfers admit they knowingly surf during health advisories — nearly the same amount that chooses not to surf during periods of elevated bacteria. About 40 percent of surfers said they were unaware if they had ever surfed during an active health advisory. The data can help public officials better warn surfers of potential health risks, said Anna Harding, co-author of the study and professor in OSU's College of Public Health and Human Sciences. "Beach advisories for bacteria are not having their intended effect of dissuading surfers," Harding said. “The lack of awareness about advisories — and willingness to take risks surfing in water that may be contaminated — suggests the need to educate surfers about behaviors that make them vulnerable to illness."
Herbicide Use To Increase Dramatically
August 15, 2014 10:50 AM - Editor, The Ecologist
The US is poised to 'deregulate' GMO corn, soybean and cotton varieties resistant to the herbicides 2,4-D and dicamba. The result will be a big increase in the use of those herbicides, as high as 600%. Only a huge public outcry can now stop the GMO-herbicide juggernaut. The US Department of Agriculture (USDA) has issued its final Environmental Impact Statement (EIS) and proposed approval for new GMO corn and soybean varieties genetically engineered to be resistant to the toxic herbicide 2,4-D.
Habitat protection for the Yellow-billed Cuckoo
August 15, 2014 08:10 AM - Center for Biological Diversity
The U.S. Fish and Wildlife Service today proposed to protect more than a half-million acres of critical habitat across the West for the yellow-billed cuckoo, a songbird that lives along rivers and streams. The bird was proposed for Endangered Species Act protection in October 2013 as part of a 2011 agreement with the Center for Biological Diversity to speed protection decisions for 757 imperiled species nationwide. Today’s proposal would protect 546,335 acres of streamside habitat in nine western states including Arizona, California, Colorado, Idaho, Nevada, New Mexico, Texas, Utah and Wyoming. "This is an important victory not just for yellow-billed cuckoos but for rivers and streams across the West," said Michael Robinson, a conservation advocate at the Center, which first petitioned for the cuckoo’s protection in 1998.
The power of distributed power!
August 14, 2014 03:03 PM - ELISA WOOD , Clean Techies
Once upon a time when a big power plant retired, it was replaced by one as big or bigger. But not anymore. Energy efficiency is increasingly reducing the need for more power. And when it is needed, distributed generation may be enough. That's how utilities increasingly view the market, according to this year's Strategic Directions: U.S. Electric Industry report issued August 12 by Black & Veatch. The report is based on a survey of 576 utility leaders from May 7 to May 27.
What can we learn from the California Rim Fire?
August 14, 2014 06:42 AM - Crystal Shepeard, Care2
August 17, 2014 will mark the one year anniversary of the Rim Fire in the California Sierra Nevadas. It was dubbed the Rim Fire due to its proximity to the Rim of the World scenic lookout. The third largest wildfire in California’s history, it burned 257,000 acres of land in Stanislaus National Forest and the western edge of Yosemite National Park, in addition to private land in neighboring counties. It cost more than $127 million to contain, and included more than $50 million in property damage. In the early hours of the fire, a deer hunter was rescued. After the hunter was taken to safety by helicopter, investigators interviewed him to see if he witnessed anything. He told them that he had slipped and caused a rock slide that may have ignited the dry vegetation. As time went on, his story changed several times, even blaming it on marijuana growers. Finally, as the fire had been raging for several weeks, he finally told the real story.
The cost of marine debris
August 12, 2014 03:53 PM - NOAA
Marine debris has many impacts on the ocean, wildlife, and coastal communities. A NOAA Marine Debris Program economic study released today shows that it can also have considerable economic costs to residents who use their local beaches. The study found that Orange County, California residents lose millions of dollars each year avoiding littered, local beaches in favor of choosing cleaner beaches that are farther away and may cost more to reach. Reducing marine debris even by 25 percent at beaches in and near Orange County could save residents roughly $32 million during three months in the summer.
The importance of maintaining seagrass
August 12, 2014 07:05 AM - Harriet Jarlett, Planet Earth Online
Seagrass meadows provide the ideal place for young fish to thrive, say NERC-funded scientists researching the importance of these habitats for commercial fishing. Globally seagrasses are being lost at the same rate as Amazonian rainforests, and little is being done to conserve these habitats as their importance isn't fully understood. But scientists at Swansea University have just published two studies in the journals Marine Pollution Bulletin and Marine Biodiversity showing these areas are vital to the wellbeing of juvenile fish, and consequently the fishing industry.
New study casts light on climate change and oceanic oxygen levels
August 10, 2014 09:55 AM - University of South Carolina via ScienceDaily
A commonly held belief that global warming will diminish oxygen concentrations in the ocean looks like it may not be entirely true. According to new research published in Science magazine, just the opposite is likely the case in the northern Pacific Ocean, with its anoxic zone expected to shrink in coming decades because of climate change. An international team of scientists came to that surprising conclusion after completing a detailed assessment of changes since 1850 in the eastern tropical northern Pacific's oxygen minimum zone (OMZ). An ocean layer beginning typically a few hundred to a thousand meters below the surface, an OMZ is by definition the zone with the lowest oxygen saturation in the water column. OMZs are a consequence of microbial respiration and can be hostile environments for marine life.
What happens immediately after an oil spill?

The fate of oil during the first day after an accidental oil spill is still poorly understood, with researchers often arriving on the scene only after several days. New findings from a field experiment carried out in the North Sea provide valuable insight The immediate aftermath of an oil spill The fate of oil during the first day after an accidental oil spill is still poorly understood, with researchers often arriving on the scene only after several days. New findings from a field experiment carried out in the North Sea provide valuable insight that could help shape the emergency response in the immediate wake of disasters.
Paint dust pollutes the oceans
August 8, 2014 09:51 AM - Erik Stokstad, Science
Even when the sea looks clean, its surface can be flecked with tiny fragments of paint and fiberglass. That's the finding from a study that looked for plastic pollution in the uppermost millimeter of ocean. The microscopic fragments come from the decks and hulls of boats, and they could pose a threat to tiny creatures called zooplankton, which are an important part of the marine food web. The discovery is "continuing to open our eyes to how many small synthetic particles are in the environment," says Kara Law, an oceanographer who studies plastic pollution at the Sea Education Association in Woods Hole, Massachusetts, and wasn’t involved in the study.
