Water quality alerts do not seem to deter some surfers
Nearly three in 10 surfers admit they knowingly surf during health advisories â€“ 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. â€œThe lack of awareness about advisories â€“ and willingness to take risks surfing in water that may be contaminated â€“ suggests the need to educate surfers about behaviors that make them vulnerable to illness." >> Read the Full Article
The cost of marine debris
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. >> Read the Full Article
New study casts light on climate change and oceanic oxygen levels
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. >> Read the Full Article
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. >> Read the Full Article
Paint dust pollutes the oceans
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 wasnâ€™t involved in the study. >> Read the Full Article
Can water-polluting drugs have a positive effect on fish?
Many studies have shown that personal care products, like toothpaste, shampoo, and other drugs that we use and get into our wastewater have negatively affected fish populations, disrupting their endocrine systems. But can there be any positive effects? A new study shows that one antianxiety drug that made its way into a lake in Sweden has in fact, positively affected the Eurasian perch population, making them bolder, less social, and more active than unexposed fish, ultimately reducing their mortality rates. >> Read the Full Article
Mercury in the oceans increasing
Although the days of odd behavior among hat makers are a thing of the past, the dangers mercury poses to humans and the environment persist today. Mercury is a naturally occurring element as well as a by-product of such distinctly human enterprises as burning coal and making cement. Estimates of "bioavailable" mercuryâ€”forms of the element that can be taken up by animals and humansâ€”play an important role in everything from drafting an international treaty designed to protect humans and the environment from mercury emissions, to establishing public policies behind warnings about seafood consumption. >> Read the Full Article
A Second Use for Cigarette Butts
It is estimated that as many as 5.6 trillion used-cigarettes, or 766,571 metric tons, are deposited into the environment worldwide every year. That's a lot of litter, especially when it takes 18 months to 10 years for cigarette filters to degrade! However, these butts may have a newly discovered second use as a group of South Korean scientists have converted these cigarette leftovers into a high-performing material that could be integrated into computers, handheld devices, electrical vehicles and wind turbines. >> Read the Full Article
Toledo, Ohio water problems
The City of Toledo has issued a "Do Not Drink" advisory for residents served by Toledo Water after chemical tests confirmed the presence of unsafe levels of the algal toxin Microcystin in the drinking water plantâ€™s finished water. The advisory, spanning three counties in Ohio and one in Michigan, leaves more than 400,000 people in the Toledo area without drinking water. "Do not drink the water," Melanie Amato, public information officer for the Ohio Department of Health, told Circle of Blue. "You can shower in it, bathe in it, but do not try to ingest it. That means no washing dishes; you can brush your teeth with it as long as you donâ€™t swallow any water, but we recommend using bottled water for that as well." >> Read the Full Article
Study predicts climate change and pollution will combine to impact food production
Many studies have shown the potential for global climate change to cut food supplies. But these studies have, for the most part, ignored the interactions between increasing temperature and air pollution -- specifically ozone pollution, which is known to damage crops. A new study involving researchers at MIT shows that these interactions can be quite significant, suggesting that policymakers need to take both warming and air pollution into account in addressing food security. >> Read the Full Article
